                                Signet Group plc

                   Change in American Depositary Share Ratio
                   -----------------------------------------


Signet Group plc ("the Company") announces that it will be changing the number
of its ordinary shares of 0.5p each ("Ordinary Shares") represented by each of
its American Depoistary Shares ("the ADSs") traded on the US Nasdaq Stock 
Market.

Each ADS (symbol SGNNY) currently represents three Ordinary Shares.  From 9:30am
(New York Time) on 4th September, 1997 each ADS will represent 30 Ordinary 
Shares of 0.5p each (new symbol SIGYY).  Any fractional ADSs arising from this 
change in the ratio will be aggregated by the Bank of New York, in its capacity
as ADS depositary, and sold with the net proceeds being distributed for the
benefit of the holders of the fractional ADSs.

Dealings in the ADSs commenced on 21st July, 1997.  Since that date the 
cancellation fee payable to the Bank of New York upon surrender of each 
American Depositary Receipt ("ADR") has been at a temporary concessionary rate.
Holders of ADRs should note that from 4th September, 1997 the cancellation fee
will revert to the rate of $5 per 100 ADSs or portion thereof (each ADS 
representing 30 Ordinary Shares of 0.5p each).
