Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description Of the Company And Summary Of Significant Accounting Policies [Text Block]	Description of the Company and Summary of Significant Accounting Policies The Company Blue Nile, Inc. (the “Company”) is a leading online retailer of high-quality diamonds and fine jewelry. In addition to sales of diamonds and fine jewelry, the Company provides education, guidance and support to enable customers to more effectively learn about and purchase diamonds and fine jewelry. The Company, a Delaware corporation, based in Seattle, Washington, was formed in March 1999. The Company serves consumers in over 40 countries and territories all over the world through its website at www.bluenile.com. Fiscal Year The Company’s fiscal year ends on the Sunday closest to December 31. Each fiscal year consists of four 13-week quarters, with one extra week added in the fourth quarter every five to six years. The Company's fiscal year 2015 ended January 3, 2016 included 52 weeks. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances are eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Some of the more significant estimates include the allowance for sales returns, accounting for taxes, and inventory valuation. Actual results could differ materially from those estimates. Foreign Currency The functional currency of most of the Company’s subsidiaries is the applicable local currency. Assets and liabilities have been translated to U.S. dollars using the exchange rates effective on the balance sheet dates, while income and expense accounts are translated at the average rates in effect during the periods presented. The resulting translation adjustments are recorded as a component of other accumulated comprehensive income within stockholders’ equity. The Company also recognizes gains and losses associated with transactions that are denominated in foreign currencies. The Company recorded a net loss resulting from foreign currency transactions of approximately $1.0 million for the fiscal year ended January 3, 2016 , approximately $0.8 million for the fiscal year ended January 4, 2015 and approximately $0.4 million for the fiscal year ended December 29, 2013 , within other income, net in the consolidated statements of operations. Concentration of Risk The Company maintains the majority of its cash and cash equivalents in accounts with six major financial institutions within and outside the United States, in the form of demand deposits, money market accounts, and time deposits. Deposits in these institutions may exceed the amounts of insurance provided, or deposits may not be covered by insurance. The Company has not experienced losses on its deposits of cash and cash equivalents. The Company’s trade accounts receivable are primarily derived from credit card purchases from customers and the majority are settled within two business days. The Company’s ability to acquire diamonds and fine jewelry is dependent on its relationships with various suppliers from whom it purchases diamonds and fine jewelry. The Company has reached agreements with certain suppliers to provide access to their inventories of diamonds for its customers, but the terms of these agreements are limited and do not govern the purchase of diamonds for its inventory. Purchase concentration by major supply vendor in fiscal year ended January 3, 2016 with comparative information for fiscal years ended January 4, 2015 and December 29, 2013 , is as follows: Year Ended January 3, January 4, December 29, Vendor A 8 % 7 % 10 % Vendor B 6 % 6 % 5 % Vendor C 5 % 5 % 5 % 19 % 18 % 20 % Cash and Cash Equivalents The Company considers all highly liquid investments with maturities of three months or less, from the date of purchase, to be cash equivalents. Inventories The Company’s diamond and fine jewelry inventories are valued at the lower of cost or market, using the specific identification method for diamonds and weighted average cost method for fine jewelry. The Company lists loose diamonds on its website that are typically not included in inventory until the Company receives a customer order for those diamonds. Upon receipt of a customer order, the Company purchases a specific diamond and records it in inventory until it is delivered to the customer, at which time the revenue from the sale is recognized and inventory is relieved. To determine if the cost of the Company's inventory should be written down, current and anticipated demand, customer preferences, age of the merchandise and fashion trends are considered. This write-down is equal to the difference between the cost of inventory and its estimated market value. The Company recorded inconsequential write-downs for the fiscal years ended January 3, 2016 , January 4, 2015 and December 29, 2013 . Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Maintenance and repairs are expensed as incurred. Depreciation expense is calculated on a straight-line basis over the estimated useful lives of the related assets. The cost and related accumulated depreciation of assets sold or otherwise disposed of are removed from the accounts and the related gain or loss is reported in the statement of operations. Estimated useful lives by major asset category are as follows: Asset Life (in years) Software 2-5 Computers and equipment 2-5 Leasehold improvements Shorter of lease term or asset life Building Shorter of lease term or asset life Furniture and fixtures 5-7 Capitalized Software The Company capitalizes costs to develop its website and internal-use software and amortizes such costs on a straight-line basis over the estimated useful life of the software once it is available for use. Costs related to the design and maintenance of internal-use software and website development are expensed as incurred. Impairment of Long-Lived Assets The Company reviews the carrying value of its long-lived assets, including property and equipment and definite-lived intangible assets, whenever events or changes in circumstances indicate that the carrying value may not be recoverable. To the extent the estimated future cash inflows attributable to the assets, less estimated future cash outflows, are less than the carrying amount, an impairment loss would be recognized. The Company did not record an impairment loss for long-lived assets for the fiscal years ended January 3, 2016 , January 4, 2015 or December 29, 2013 . Amortizable Intangible Assets Intangible assets are recorded at cost and consist primarily of the costs incurred to acquire licenses and other similar agreements with finite lives. The gross carrying amount of these licenses was approximately $533,000 at both January 3, 2016 and January 4, 2015 . Accumulated amortization was approximately $485,000 at January 3, 2016 and $464,000 at January 4, 2015 . Amortization expense was approximately $22,000 in the fiscal year ended January 3, 2016 , $37,000 in the fiscal year ended January 4, 2015 and $55,000 in the fiscal year ended December 29, 2013 . Amortization expense is estimated to be $19,000 in fiscal 2016 , $14,000 in fiscal 2017 , $9,000 in fiscal 2018 , $3,000 in fiscal 2019 , $1,000 in fiscal 2020 and $2,000 thereafter. Note Receivable and Other Investments The Company holds a minority ownership of a privately-held company in the form of convertible preferred shares, purchased for an aggregate amount of $2.0 million , which we account for under the cost method of accounting. The Company held a $2.0 million note receivable (the "Note") from the same privately-held company. During the year ended January 3, 2016 , the Company received payment of $1.4 million on the principal amount, with the remainder of the principal collectable within a year. The interest rate changes over the term of the Note to LIBOR plus a predetermined rate per annum . The Note is recorded at its face amount on the Company's consolidated balance sheet. The Company holds a minority ownership in another privately-held company in the form of common stock and warrants, purchased for $280,000 , which we account for under the cost method of accounting. The Company reviews the investments for impairment when events and circumstances indicate that the decline in fair value of the asset below the carrying value is other-than-temporary. This evaluation consists of several qualitative and quantitative factors regarding the severity and duration of the unrealized loss as well as the Company's ability and intent to hold the investment until a forecasted recovery occurs. Additionally, the Company assesses whether it has plans to sell the security or it is more likely than not that the Company will be required to sell the investment before recovery of its amortized cost basis. Factors considered include recent and projected financial results and operating trends; publicly available information that may affect the value of the investment; duration and severity of the decline in value; and our strategy and intentions for holding the investment. Fair Value of Financial Instruments The carrying amounts for the Company’s cash, cash equivalents, accounts receivable, note receivable, accounts payable and accrued liabilities approximate fair value due to their short maturities. Treasury Stock Treasury stock is recorded at cost and consists primarily of the repurchase of the Company’s common stock in the open market. Income Taxes Deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities and are measured using the tax rates that will be in effect when the differences are expected to reverse. Future tax benefits, such as return reserves, are recognized to the extent that realization of such benefits is considered to be more likely than not. The Company utilizes a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company considers many factors when evaluating and estimating tax positions and tax benefits, which may require periodic adjustments and which may not accurately forecast actual outcomes. If applicable, interest and penalties related to unrecognized tax benefits are included in the provision for income taxes. Revenue Recognition Net sales consist of products sold via the Internet and shipping revenue, net of estimated returns and promotional discounts and excluding sales taxes. The Company recognizes revenue when all of the following have occurred: persuasive evidence of an agreement with the customer exists, delivery has occurred or services have been rendered, the selling price is fixed or determinable and collectability of the selling price is reasonably assured. The Company evaluates whether it is appropriate to record the gross amount of product sales and related costs or the net amount earned. Revenue is recorded at the gross amount when the Company is the primary obligor, is subject to inventory and credit risk, has latitude in establishing price and product specification, or has most of these indicators. When the Company is not primarily obligated and has no latitude in establishing the price, revenue will be recorded at the net amount earned. The Company requires payment at the point of sale. Amounts received before the customer assumes the risk of loss are not recorded as revenue. For sales to customers, the Company recognizes revenue when delivery has occurred, as this is when the risk of loss transfers, which is typically one to three days after shipment. The Company generally offers a return policy of 30 days and provides an allowance for sales returns during the period in which the sales are made. At January 3, 2016 and January 4, 2015 , the reserve for sales returns was $1.3 million and $1.0 million , respectively, and was recorded as an accrued liability. Sales and cost of sales reported in the consolidated statements of operations are reduced to reflect estimated returns. The estimates are based on the Company’s historical product return rates and current economic conditions. The Company currently has a lifetime diamond upgrade program on all certified diamonds purchased since the Company's inception. This is accounted for as a guarantee and at January 3, 2016 and January 4, 2015 , the estimated fair value of the guarantee was inconsequential. The Company generally does not extend credit to customers, except through third party credit cards. The majority of sales are through credit cards, and trade accounts receivable are composed primarily of amounts due from financial institutions related to credit card sales. The Company does not maintain an allowance for doubtful accounts because payment is typically received within two business days after the sale is complete. Shipping and Handling Costs The Company’s shipping and handling costs primarily include payments to third-parties for shipping merchandise to the Company’s customers. Shipping and handling costs of approximately $4.6 million , $4.8 million and $4.6 million in the fiscal years ended January 3, 2016 , January 4, 2015 and December 29, 2013 , respectively, were included in cost of sales. Cost of Sales Cost of sales consists of the cost of merchandise sold to customers, inbound and outbound shipping costs, insurance on shipments, the costs incurred to set diamonds into ring, earring and pendant settings, including labor and related facility costs, and depreciation on assembly related property, plant and equipment. Selling, General and Administrative Expenses Selling, general and administrative expenses consist primarily of payroll and related benefit costs for the Company’s employees, marketing costs, stock-based compensation and credit card fees. These expenses also include certain facility-related costs, and fulfillment, customer service, technology and depreciation expenses, as well as professional fees and other general corporate expenses. Fulfillment costs include costs incurred in operating and staffing the fulfillment center, including costs attributable to receiving, inspecting and warehousing inventories and picking, packaging and preparing customers’ orders for shipment. Fulfillment costs in the years ended January 3, 2016 , January 4, 2015 and December 29, 2013 were approximately $2.8 million , $3.3 million and $3.6 million , respectively. Marketing Marketing costs are expensed as incurred. Costs associated with web portal advertising contracts are amortized over the period such advertising is expected to be used. Costs of advertising associated with radio, print and other media are expensed when such services are used. Marketing expense for the fiscal years ended January 3, 2016 , January 4, 2015 and December 29, 2013 was approximately $27.1 million , $25.0 million and $24.3 million , respectively. Stock-Based Compensation The Company measures compensation cost for all stock options and RSUs granted based on fair value on the measurement date, which is typically the grant date. The fair value of each stock option granted is estimated on the grant date using the Black-Scholes-Merton option valuation model. The fair value of each RSU is based on the fair market value of the Company’s common stock on the date of the grant. Stock-based compensation expense is recognized on a straight-line basis over the requisite service period for each stock option or RSU grant expected to vest with forfeitures estimated at the date of grant based on the Company’s historical experience and future expectations. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), “Revenue from Contracts with Customers (Topic 606)” which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date”, which delays the effective date by one year effective on the first quarter of 2018, with the option to adopt in the first quarter of 2017. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements as well as the expected adoption method and related disclosures. In July 2015, the FASB issued guidance on the subsequent measurement of inventory, which changes the measurement from lower of cost or market to lower of cost and net realizable value. The guidance will require prospective application at the beginning of the Company’s first quarter of fiscal year 2017, but permits adoption in an earlier period. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements and the timing of adoption. In November 2015, the FASB issued Accounting Standards Update No. 2015-17 (“ASU 2015-17”), “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes” which simplifies the presentation of deferred income taxes by requiring deferred tax assets and liabilities to be classified as noncurrent on the balance sheet. ASU 2015-17 is effective for periods beginning on January 1, 2017 and may be applied prospectively or retrospectively. Early adoption is permitted. The Company early-adopted the guidance in ASU 2015-17 and has classified its deferred income tax assets as noncurrent in the accompanying consolidated balance sheet as of January 3, 2016. The Company applied this updated guidance retrospectively. The impact of early adopting ASU 2015-17 resulted in a reclassification of our current deferred income tax asset to the non-current deferred income tax asset in the amount of $1.1 million, in our previously presented consolidated balance sheet as of January 4, 2015. In January 2016, the FASB issued Accounting Standards Update No. 2016-01 “Financial Instruments - Overall (“ASU 2016-01”),“Recognition and Measurement of Financial Assets and Financial Liabilities” which amends various aspects of recognition, measurement, presentation and disclosure of financial instruments. With respect to our consolidated financial statements the most significant impact of this update will be revising certain classification and measurement of our investments in equity securities accounted for under the cost method. This update will require prospective application at the beginning of the Company's first quarter of fiscal year 2018. For certain provisions, early adoption is permitted.The Company is currently evaluating the impact this update will have on its consolidated financial statements and related disclosures. In February 2016, the FASB issued Accounting Standards Update No. 2016-02 "Leases (Topic 842)", which increases transparency and comparability among companies accounting for lease transactions. The most significant change of this update will require the recognition of lease assets and liabilities on the balance sheet for operating lease arrangements with lease terms greater than 12 months for lessees. This update will require a modified retrospective application which includes a number of optional practical expedients related to the identification and classification of leases commenced before the effective date. This update will become effective beginning the first quarter of the Company's fiscal year 2019. Early application is permitted. The Company is currently evaluating the impact this update will have on its consolidated financial statements and the timing of adoption.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Commitments and Contingencies In the ordinary course of business, the Company may be subject from time to time to various proceedings, lawsuits, disputes or claims. In addition, the Company is regularly audited by various tax authorities. Although the Company cannot predict with assurance the outcome of any litigation or audit, it does not believe there are currently any such actions that, if resolved unfavorably, would have a material impact on the Company’s financial condition, results of operations or cash flows. Leases The Company leases its office and warehouse facilities and some equipment under non-cancelable lease agreements with initial terms that generally range from one to eleven years. Some of the leases include renewal provisions at the Company’s option. At the inception of the lease, the Company evaluates each agreement to determine whether the lease will be accounted for as an operating or capital lease. The term of the lease used for this evaluation includes renewal option periods only in instances in which the exercise of the renewal option can be reasonably assured and failure to exercise such option would result in an economic penalty. Some of the office leases contain rent escalation clauses and rent holidays. Rent expense is recorded on a straight-line basis over the lease term with the difference between the rent paid and the straight-line rent expense recorded as a deferred rent liability. Lease incentive payments received from the landlord are recorded as deferred rent liabilities and are amortized on a straight-line basis over the lease term as a reduction in rent. For January 3, 2016 and January 4, 2015 , the deferred rent balance related to lease incentives was approximately $1.4 million and $1.7 million , respectively. On May 5, 2014, the Company entered into the Third Amendment to the Commercial Lease Agreement dated July 21, 2006 for its U.S. fulfillment center. The future minimum lease payments are included in the operating lease schedule below. During 2007, the Company made tenant improvements to its U.S. fulfillment center. Due to its financial involvement in the construction of the leased property, the Company recorded the building as property and equipment during the construction period. Upon completion, the transaction did not meet the criteria for sale-leaseback accounting, and accordingly, has been recorded as a long-term financing obligation. Future minimum lease payments at January 3, 2016 are as follows (in thousands): Financing Obligation Operating Leases 2016 $ 36 $ 1,590 2017 36 1,493 2018 37 1,349 2019 30 1,266 2020 — 1,144 Thereafter — 769 Total minimum lease payments 139 $ 7,611 Less: amounts representing interest (6 ) Present value of minimum lease payments 133 Residual value 355 Less: current portion (33 ) Total long-term financing obligation less current portion $ 455 Assets under the long-term financing obligation amounted to $0.5 million at January 3, 2016 and January 4, 2015 , respectively. These amounts are net of accumulated depreciation of approximately $54,000 as of January 3, 2016 and $20,000 as of January 4, 2015 . Such assets are classified within property and equipment, net, in the accompanying balance sheets. The residual value of the long-term financing obligation represents the estimated fair value of the financing at the end of the Company’s lease term. Rent expense under non-cancelable lease terms which includes certain common area maintenance costs, was approximately $1.4 million , $1.3 million and $1.0 million for the fiscal years ended January 3, 2016 , January 4, 2015 and December 29, 2013 , respectively.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Stock-Based Compensation Share-based Plans As of January 3, 2016 , the Company has a total of four equity plans. The Company’s 2004 Equity Incentive Plan (“2004 Plan”) provides for the grant of non-statutory stock options, restricted stock awards, stock appreciation rights, RSUs and other forms of equity compensation, which may be granted to employees, including officers, non-employee directors and consultants. Upon the effectiveness of the 2013 Plan (as defined below), the 2004 Plan was suspended and any equity compensation that would have been granted under the 2004 Plan was thereafter granted under the 2013 Plan. The Company’s 2004 Non-Employee Directors’ Stock Option Plan (“Directors’ Plan”) provides for the automatic grant of non-statutory stock options to purchase shares of common stock to non-employee directors. In April 2012, the Directors' Plan was suspended; therefore, any equity compensation that would have been granted under the Directors' Plan is now granted under the 2004 Plan. Upon the effectiveness of the 2013 Plan, any equity compensation that would have been granted under the Directors' Plan is now granted under the 2013 Plan. On May 21, 2013, the Company adopted the 2013 Equity Incentive Plan (“2013 Plan”). The 2013 Plan provides for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance stock awards, performance cash awards and other stock awards. The 2013 Plan is intended to be the successor to the 2004 Plan and the Directors' Plan. Any equity compensation that would have been granted under the 2004 Plan or Directors' Plan is now granted under the 2013 Plan. As of January 3, 2016 , there were 1,126,304 shares of common stock reserved for future grants under the 2013 Plan. The majority of options granted generally provide for 25% vesting on the first anniversary from the date of grant with the remainder vesting monthly over the subsequent three years and expire 10 years from the date of grant. All of our outstanding stock options are non-qualified stock options. RSUs generally vest 25% on the first anniversary from the date of grant with the remaining vesting quarterly over three years. Employee Stock Purchase Plans In April 2004, the Company adopted the 2004 Employee Stock Purchase Plan (the “Purchase Plan”). As of January 3, 2016 , 1,000,000 shares of common stock are authorized to be sold under the Purchase Plan. Commencing on the first day of the fiscal year in which the Company first makes an offering under the Purchase Plan, this amount will be increased annually for 20 years. The increase in amount is the lesser of 320,000 shares or one and one half percent of the number of shares of common stock outstanding on each such date, unless a lower number of shares is approved by the board of directors. The Purchase Plan is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Internal Revenue Code. As of January 3, 2016 , no shares of common stock have been offered for sale under the Purchase Plan. Stock-Based Compensation Expense The following weighted average assumptions were used for the valuation of stock options granted during the periods presented: Year Ended January 3, January 4, December 29, Expected term 4.5 years 4.5 years 4.5 years Expected volatility 46.8 % 46.9 % 56.9 % Expected dividend yield 0.0 % 0.0 % 0.0 % Risk-free interest rate 1.5 % 1.5 % 0.9 % Estimated weighted average fair value per option granted $ 11.38 $ 13.28 $ 14.68 • Expected Term — This is the estimated period of time until exercise and is based primarily on historical experience for options with similar terms and conditions, giving consideration to future expectations. • Expected Volatility — This is based on the Company’s historical stock price volatility commensurate with the expected term of the options on the date of grant. • Expected Dividend Yield — The Company has not paid dividends during the periods presented. Any future payment of dividends will be at the discretion of our board of directors. • Risk-Free Interest Rate — This is the rate on nominal U.S. Government Treasury Bills with lives commensurate with the expected term of the options on the date of grant. The assumptions used to calculate the fair value of options granted are evaluated and revised, as necessary, to reflect market conditions and the Company’s experience. The following table represents total stock-based compensation expense recognized in the consolidated financial statements (in thousands): Year Ended January 3, January 4, December 29, Stock-based compensation expense in selling, general and administrative expenses $ 4,944 $ 4,196 $ 4,860 Stock-based compensation expense in cost of sales 97 85 88 Total stock-based compensation expense in the consolidated statements of operations $ 5,041 $ 4,281 $ 4,948 Total related tax benefit $ 1,764 $ 1,498 $ 1,732 Stock-based compensation capitalized $ 110 $ 106 $ 158 Stock-based compensation capitalized is included in property and equipment, net, in the consolidated balance sheets as a component of the cost capitalized for website development and the development of software for internal use. As of January 3, 2016 , the Company had total unrecognized compensation costs related to unvested stock options and RSUs of approximately $8.0 million , before income taxes.

Description Of the Company And Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Jan. 03, 2016
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Principles Of Consolidation, Policy [Policy Text Block]	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances are eliminated in consolidation.
Use Of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Some of the more significant estimates include the allowance for sales returns, accounting for taxes, and inventory valuation. Actual results could differ materially from those estimates.
Foreign Currency, Policy [Policy Text Block]	Foreign Currency The functional currency of most of the Company’s subsidiaries is the applicable local currency. Assets and liabilities have been translated to U.S. dollars using the exchange rates effective on the balance sheet dates, while income and expense accounts are translated at the average rates in effect during the periods presented. The resulting translation adjustments are recorded as a component of other accumulated comprehensive income within stockholders’ equity. The Company also recognizes gains and losses associated with transactions that are denominated in foreign currencies. The Company recorded a net loss resulting from foreign currency transactions of approximately $1.0 million for the fiscal year ended January 3, 2016 , approximately $0.8 million for the fiscal year ended January 4, 2015 and approximately $0.4 million for the fiscal year ended December 29, 2013 , within other income, net in the consolidated statements of operations.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents The Company considers all highly liquid investments with maturities of three months or less, from the date of purchase, to be cash equivalents.
Inventories, Policy [Policy Text Block]	Inventories The Company’s diamond and fine jewelry inventories are valued at the lower of cost or market, using the specific identification method for diamonds and weighted average cost method for fine jewelry. The Company lists loose diamonds on its website that are typically not included in inventory until the Company receives a customer order for those diamonds. Upon receipt of a customer order, the Company purchases a specific diamond and records it in inventory until it is delivered to the customer, at which time the revenue from the sale is recognized and inventory is relieved. To determine if the cost of the Company's inventory should be written down, current and anticipated demand, customer preferences, age of the merchandise and fashion trends are considered. This write-down is equal to the difference between the cost of inventory and its estimated market value. The Company recorded inconsequential write-downs for the fiscal years ended January 3, 2016 , January 4, 2015 and December 29, 2013 .
Property and Equipment, Policy [Policy Text Block]	Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Maintenance and repairs are expensed as incurred. Depreciation expense is calculated on a straight-line basis over the estimated useful lives of the related assets. The cost and related accumulated depreciation of assets sold or otherwise disposed of are removed from the accounts and the related gain or loss is reported in the statement of operations. Estimated useful lives by major asset category are as follows: Asset Life (in years) Software 2-5 Computers and equipment 2-5 Leasehold improvements Shorter of lease term or asset life Building Shorter of lease term or asset life Furniture and fixtures 5-7
Capitalized Software, Policy [Policy Text Block]	Capitalized Software The Company capitalizes costs to develop its website and internal-use software and amortizes such costs on a straight-line basis over the estimated useful life of the software once it is available for use. Costs related to the design and maintenance of internal-use software and website development are expensed as incurred.
Impairment of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-Lived Assets The Company reviews the carrying value of its long-lived assets, including property and equipment and definite-lived intangible assets, whenever events or changes in circumstances indicate that the carrying value may not be recoverable. To the extent the estimated future cash inflows attributable to the assets, less estimated future cash outflows, are less than the carrying amount, an impairment loss would be recognized.
Amortizable Intangible Assets, Policy [Policy Text Block]	Amortizable Intangible Assets Intangible assets are recorded at cost and consist primarily of the costs incurred to acquire licenses and other similar agreements with finite lives. The gross carrying amount of these licenses was approximately $533,000 at both January 3, 2016 and January 4, 2015 . Accumulated amortization was approximately $485,000 at January 3, 2016 and $464,000 at January 4, 2015 . Amortization expense was approximately $22,000 in the fiscal year ended January 3, 2016 , $37,000 in the fiscal year ended January 4, 2015 and $55,000 in the fiscal year ended December 29, 2013 . Amortization expense is estimated to be $19,000 in fiscal 2016 , $14,000 in fiscal 2017 , $9,000 in fiscal 2018 , $3,000 in fiscal 2019 , $1,000 in fiscal 2020 and $2,000 thereafter.
Note Receivable and Other Investments, Policies [Policy Text Block]	Note Receivable and Other Investments The Company holds a minority ownership of a privately-held company in the form of convertible preferred shares, purchased for an aggregate amount of $2.0 million , which we account for under the cost method of accounting. The Company held a $2.0 million note receivable (the "Note") from the same privately-held company. During the year ended January 3, 2016 , the Company received payment of $1.4 million on the principal amount, with the remainder of the principal collectable within a year. The interest rate changes over the term of the Note to LIBOR plus a predetermined rate per annum . The Note is recorded at its face amount on the Company's consolidated balance sheet. The Company holds a minority ownership in another privately-held company in the form of common stock and warrants, purchased for $280,000 , which we account for under the cost method of accounting. The Company reviews the investments for impairment when events and circumstances indicate that the decline in fair value of the asset below the carrying value is other-than-temporary. This evaluation consists of several qualitative and quantitative factors regarding the severity and duration of the unrealized loss as well as the Company's ability and intent to hold the investment until a forecasted recovery occurs. Additionally, the Company assesses whether it has plans to sell the security or it is more likely than not that the Company will be required to sell the investment before recovery of its amortized cost basis. Factors considered include recent and projected financial results and operating trends; publicly available information that may affect the value of the investment; duration and severity of the decline in value; and our strategy and intentions for holding the investment.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments The carrying amounts for the Company’s cash, cash equivalents, accounts receivable, note receivable, accounts payable and accrued liabilities approximate fair value due to their short maturities.
Treasury Stock, Policy [Text Block]	Treasury Stock Treasury stock is recorded at cost and consists primarily of the repurchase of the Company’s common stock in the open market.
Income Tax, Policy [Policy Text Block]	Income Taxes Deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities and are measured using the tax rates that will be in effect when the differences are expected to reverse. Future tax benefits, such as return reserves, are recognized to the extent that realization of such benefits is considered to be more likely than not. The Company utilizes a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. The Company considers many factors when evaluating and estimating tax positions and tax benefits, which may require periodic adjustments and which may not accurately forecast actual outcomes. If applicable, interest and penalties related to unrecognized tax benefits are included in the provision for income taxes.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition Net sales consist of products sold via the Internet and shipping revenue, net of estimated returns and promotional discounts and excluding sales taxes. The Company recognizes revenue when all of the following have occurred: persuasive evidence of an agreement with the customer exists, delivery has occurred or services have been rendered, the selling price is fixed or determinable and collectability of the selling price is reasonably assured. The Company evaluates whether it is appropriate to record the gross amount of product sales and related costs or the net amount earned. Revenue is recorded at the gross amount when the Company is the primary obligor, is subject to inventory and credit risk, has latitude in establishing price and product specification, or has most of these indicators. When the Company is not primarily obligated and has no latitude in establishing the price, revenue will be recorded at the net amount earned. The Company requires payment at the point of sale. Amounts received before the customer assumes the risk of loss are not recorded as revenue. For sales to customers, the Company recognizes revenue when delivery has occurred, as this is when the risk of loss transfers, which is typically one to three days after shipment. The Company generally offers a return policy of 30 days and provides an allowance for sales returns during the period in which the sales are made. At January 3, 2016 and January 4, 2015 , the reserve for sales returns was $1.3 million and $1.0 million , respectively, and was recorded as an accrued liability. Sales and cost of sales reported in the consolidated statements of operations are reduced to reflect estimated returns. The estimates are based on the Company’s historical product return rates and current economic conditions. The Company currently has a lifetime diamond upgrade program on all certified diamonds purchased since the Company's inception. This is accounted for as a guarantee and at January 3, 2016 and January 4, 2015 , the estimated fair value of the guarantee was inconsequential. The Company generally does not extend credit to customers, except through third party credit cards. The majority of sales are through credit cards, and trade accounts receivable are composed primarily of amounts due from financial institutions related to credit card sales. The Company does not maintain an allowance for doubtful accounts because payment is typically received within two business days after the sale is complete.
Shipping and Handling Costs, Policy [Policy Text Block]	Shipping and Handling Costs The Company’s shipping and handling costs primarily include payments to third-parties for shipping merchandise to the Company’s customers. Shipping and handling costs of approximately $4.6 million , $4.8 million and $4.6 million in the fiscal years ended January 3, 2016 , January 4, 2015 and December 29, 2013 , respectively, were included in cost of sales.
Cost of Sales, Policy [Policy Text Block]	Cost of Sales Cost of sales consists of the cost of merchandise sold to customers, inbound and outbound shipping costs, insurance on shipments, the costs incurred to set diamonds into ring, earring and pendant settings, including labor and related facility costs, and depreciation on assembly related property, plant and equipment.
Selling, General and Administrative Expenses, Policy [Policy Text Block]	Selling, General and Administrative Expenses Selling, general and administrative expenses consist primarily of payroll and related benefit costs for the Company’s employees, marketing costs, stock-based compensation and credit card fees. These expenses also include certain facility-related costs, and fulfillment, customer service, technology and depreciation expenses, as well as professional fees and other general corporate expenses. Fulfillment costs include costs incurred in operating and staffing the fulfillment center, including costs attributable to receiving, inspecting and warehousing inventories and picking, packaging and preparing customers’ orders for shipment. Fulfillment costs in the years ended January 3, 2016 , January 4, 2015 and December 29, 2013 were approximately $2.8 million , $3.3 million and $3.6 million , respectively.
Marketing, Policy [Policy Text Block]	Marketing Marketing costs are expensed as incurred. Costs associated with web portal advertising contracts are amortized over the period such advertising is expected to be used. Costs of advertising associated with radio, print and other media are expensed when such services are used. Marketing expense for the fiscal years ended January 3, 2016 , January 4, 2015 and December 29, 2013 was approximately $27.1 million , $25.0 million and $24.3 million , respectively.
Stock-Based Compensation, Policy [Policy Text Block]	Stock-Based Compensation The Company measures compensation cost for all stock options and RSUs granted based on fair value on the measurement date, which is typically the grant date. The fair value of each stock option granted is estimated on the grant date using the Black-Scholes-Merton option valuation model. The fair value of each RSU is based on the fair market value of the Company’s common stock on the date of the grant. Stock-based compensation expense is recognized on a straight-line basis over the requisite service period for each stock option or RSU grant expected to vest with forfeitures estimated at the date of grant based on the Company’s historical experience and future expectations.
Recently Issued and Adopted Accounting Pronouncement [Policy Text Block]	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), “Revenue from Contracts with Customers (Topic 606)” which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on the principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date”, which delays the effective date by one year effective on the first quarter of 2018, with the option to adopt in the first quarter of 2017. The Company is currently evaluating the effect that the updated standard will have on its consolidated financial statements as well as the expected adoption method and related disclosures. In July 2015, the FASB issued guidance on the subsequent measurement of inventory, which changes the measurement from lower of cost or market to lower of cost and net realizable value. The guidance will require prospective application at the beginning of the Company’s first quarter of fiscal year 2017, but permits adoption in an earlier period. The Company is currently evaluating the impact this guidance will have on its consolidated financial statements and the timing of adoption. In November 2015, the FASB issued Accounting Standards Update No. 2015-17 (“ASU 2015-17”), “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes” which simplifies the presentation of deferred income taxes by requiring deferred tax assets and liabilities to be classified as noncurrent on the balance sheet. ASU 2015-17 is effective for periods beginning on January 1, 2017 and may be applied prospectively or retrospectively. Early adoption is permitted. The Company early-adopted the guidance in ASU 2015-17 and has classified its deferred income tax assets as noncurrent in the accompanying consolidated balance sheet as of January 3, 2016. The Company applied this updated guidance retrospectively. The impact of early adopting ASU 2015-17 resulted in a reclassification of our current deferred income tax asset to the non-current deferred income tax asset in the amount of $1.1 million, in our previously presented consolidated balance sheet as of January 4, 2015. In January 2016, the FASB issued Accounting Standards Update No. 2016-01 “Financial Instruments - Overall (“ASU 2016-01”),“Recognition and Measurement of Financial Assets and Financial Liabilities” which amends various aspects of recognition, measurement, presentation and disclosure of financial instruments. With respect to our consolidated financial statements the most significant impact of this update will be revising certain classification and measurement of our investments in equity securities accounted for under the cost method. This update will require prospective application at the beginning of the Company's first quarter of fiscal year 2018. For certain provisions, early adoption is permitted.The Company is currently evaluating the impact this update will have on its consolidated financial statements and related disclosures. In February 2016, the FASB issued Accounting Standards Update No. 2016-02 "Leases (Topic 842)", which increases transparency and comparability among companies accounting for lease transactions. The most significant change of this update will require the recognition of lease assets and liabilities on the balance sheet for operating lease arrangements with lease terms greater than 12 months for lessees. This update will require a modified retrospective application which includes a number of optional practical expedients related to the identification and classification of leases commenced before the effective date. This update will become effective beginning the first quarter of the Company's fiscal year 2019. Early application is permitted. The Company is currently evaluating the impact this update will have on its consolidated financial statements and the timing of adoption.
