	Description of Our Business and Summary of Significant Accounting Policies
	The Company
	Blue Nile, Inc. ("Blue Nile" or the “Company”) is the 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 and maintains its website at www.bluenile.com. Information found on the Company’s website is not incorporated by reference into this Quarterly Report on Form 10-Q or any of its other filings with the U.S. Securities and Exchange Commission (the “SEC”).
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Notes to Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for the year ended December 30, 2012, filed with the SEC on February 25, 2013 (the "Annual Report"). The same accounting policies are followed for preparing quarterly and annual financial statements. In the opinion of management, all adjustments necessary for the fair presentation of the financial position, results of operations and cash flows for the interim periods have been included and are of a normal, recurring nature.
	The financial information as of December 30, 2012 is derived from the Company’s audited consolidated financial statements and notes thereto for the fiscal year ended December 30, 2012, included in Item 8 of the Annual Report.
	Due to a number of factors, including the seasonal nature of the retail industry and other factors described in this report, quarterly results are not necessarily indicative of the results for the full fiscal year or any other subsequent interim period.
	Principles of Consolidation
	The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All transactions and balances between the Company and its wholly-owned subsidiaries 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 income taxes, and assumptions used to determine stock-based compensation expense. Actual results could differ materially from those estimates.
	During the quarter-ended September 29, 2013, there was a change in accounting estimate relating to our income tax expense. We recognized an income tax benefit resulting primarily from the domestic production activities deduction related to the current and prior tax years recorded in the quarter-ended September 29, 2013. The out-of-period impact of this deduction decreased our income tax expense and increased our net income by $1.1 million and $0.08 per diluted share for the quarter and year-to-date ended September 29, 2013.
	In addition, as a result primarily of this deduction, our effective tax rate decreased to (14.2)% in the third quarter of 2013 from 35.6% in the third quarter of 2012 and our effective tax rate decreased to 18.8% in the year-to-date ended September 29, 2013 from 35.8% in the year-to-date ended September 30, 2012.
	Foreign Currency
	The assets and liabilities of our subsidiaries 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 in accumulated other comprehensive income (loss).
	The Company offers customers the ability to transact in 25 currencies. Some of the Company’s subsidiaries engage in transactions denominated in currencies other than the Company’s functional currency. Gains or losses arising from these transactions are recorded in other income, net in the condensed consolidated statements of operations.
	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 accounted for under the cost method of accounting.
	The Company holds a $2.0 million note receivable (the "Note") from the same privately-held company. 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 condensed consolidated balance sheet.
	During the quarter ended September 29, 2013, the Company purchased, for $280,000, a minority ownership in another privately-held company in the form of common stock and warrants, which we accounted for under the cost method of accounting.
	The Company reviews its investments for impairment when events and circumstances indicate that the decline in fair value of the assets below the carrying value is other-than-temporary. No other-than-temporary impairment charges were recorded for the year-to-date ended September 29, 2013.
	Credit Agreement
	On February 11, 2013, the Company entered into a Credit Agreement (the "Credit Agreement") with U.S. Bank National Association (the "Lender"). The Credit Agreement provides for a $35.0 million (the "Credit Limit") unsecured, revolving credit facility. The Credit Agreement terminates on February 11, 2014 (the "Line Termination Date"). Under the terms and conditions of the Credit Agreement, the Company may borrow from the Lender until the Line Termination Date, with the aggregate principal amounts outstanding at any one time not to exceed the Credit Limit.
	As of the filing date of this Quarterly Report on Form 10-Q, the Company does not have any amounts outstanding under the Credit Agreement and is in compliance with the covenants of the Credit Agreement.

Share-based Compensation [Abstract]	'
Stock-Based Compensation	'
	Stock-based Compensation
	On May 21, 2013, the date of the Company's 2013 Annual Meeting of Stockholders (the "Annual Meeting"), the Company's stockholders approved the 2013 Equity Incentive Plan (the “2013 Plan”), effective as of such date. The 2013 Plan is intended to be the successor to the Company's 2004 Equity Incentive Plan (the “2004 Plan”) and the Blue Nile, Inc. Third Amended and Restated 2004 Non-Employee Directors Stock Option Plan (the “Directors' Plan”).
	As of September 29, 2013, with the addition of the 2013 Plan, the Company has a total of five equity plans. Once the 2013 Plan became effective, the 2004 Plan was suspended and any equity compensation that would have been granted under the 2004 Plan is now granted under the 2013 Plan. The Directors' Plan was suspended in April 2012 and no equity compensation has been granted under the Directors' Plan since that date. Any equity compensation that would have been granted under the Directors' Plan is now granted under the 2013 Plan.
	Additional information regarding the former plans is disclosed in the Annual Report.
	Stock-based compensation expense, net of estimated forfeitures, is recognized on a straight-line basis over the vesting period for each stock option or restricted stock unit ("RSU") grant expected to vest with forfeitures estimated at the date of grant based on the Company's historical experience and future expectations.
	The fair value of each stock option on the date of grant is estimated 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.
	During the quarter ended September 29, 2013, there were no stock options granted. The following weighted-average assumptions were used for the valuation of stock options granted during the fiscal year-to-date periods presented:
		Year to date ended
		September 29,				September 30,
		2013				2012
	Expected term	4.5 years				4.3 years
	Expected volatility	56.9		%		59.1		%
	Expected dividend yield	0		%		0		%
	Risk-free interest rate	0.9		%		0.7		%
	Estimated weighted-average fair value per stock option granted	$	14.68			$	15.43
	The assumptions used to calculate the fair value of stock options granted are evaluated and revised, if necessary, to reflect market conditions and the Company’s experience.
	A summary of stock option activity for the year-to-date ended September 29, 2013 is as follows:
		Options			Weighted			Weighted	Aggregate
		(in thousands)			Average			Average	Intrinsic Value

	The aggregate intrinsic value in the tables above are before applicable income taxes and represent the amount recipients would have received if all stock options had been exercised or RSUs had been released on the last business day of the period indicated, based on the closing stock price of the Company's common stock on such date.
	The total intrinsic value of stock options exercised during the year-to-date ended September 29, 2013 was $3.7 million. During the year-to-date ended September 29, 2013, the total fair value of stock options vested was $3.9 million. As of September 29, 2013, the Company had total unrecognized compensation costs related to unvested stock options and RSUs of $8.9 million, before income taxes. The Company expects to recognize this cost over a weighted average period of 2.6 years for the options and 3.2 years for the RSUs.

	Basic net income per share is based on the weighted average number of common shares outstanding. Diluted net income per share is based on the weighted average number of common shares and common share equivalents outstanding. Common share equivalents included in the computation represent shares issuable upon assumed exercise of outstanding stock options and conversion of unvested RSUs, except when the effect of their inclusion would be antidilutive.
	The following tables set forth the computation of basic and diluted net income per share (in thousands, except per share data):

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	'
	Stock-based compensation expense, net of estimated forfeitures, is recognized on a straight-line basis over the vesting period for each stock option or restricted stock unit ("RSU") grant expected to vest with forfeitures estimated at the date of grant based on the Company's historical experience and future expectations.
	The fair value of each stock option on the date of grant is estimated 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.

	Basic net income per share is based on the weighted average number of common shares outstanding. Diluted net income per share is based on the weighted average number of common shares and common share equivalents outstanding. Common share equivalents included in the computation represent shares issuable upon assumed exercise of outstanding stock options and conversion of unvested RSUs, except when the effect of their inclusion would be antidilutive.
