                 SIGNET ANNOUNCES FOURTH QUARTER SALES

Signet Group plc (LSE: SIG and NYSE: SIG), the world's largest speciality retail
jeweller, today announced its sales performance for the 14 weeks and year ended
3 February 2007.

14 WEEKS TO 3 FEBRUARY 2007
Group like for like sales rose by 4.2% in the 14 weeks to 3 February 2007, with
growth in US sales adversely affected due to the change in timing of a
promotional event (see note b below table). On a 13 week basis to 27 January
2007, which is not impacted by this promotional timing difference, like for like
sales were up 5.6%. Total sales for the 14 week period increased by 14.3% at
constant exchange rates (see note 1) and by 5.0% on a reported basis to £754.6
million (2005/06: £718.9 million).

2007 like for like sales were up 5.4%. Group sales for the 53 week period
increased by 11.5% at constant exchange rates (see note 1), and by 8.1% on a

final week that was impacted by the timing of a promotional event associated
with Valentine's Day. The UK division made satisfactory progress.

For the year as a whole the US business again increased its share of the $60
billion US jewellery market, with like for like sales up by 7.0% on a 52 week
basis. On the same basis, UK like for like sales were up 1.1% in a challenging
retail environment."

Note 1 - Impact of constant exchange rates

The Group has historically used constant exchange rates to compare
period-to-period changes in certain financial data. This is referred to as 'at
constant exchange rates' throughout this release. The Group considers this to be
a useful measure for analysing and explaining changes and trends in the Group's
results. The impact of the re-calculation of sales growth at constant exchange
rates is shown below.
