World Leading Diamantaire Laurence Graff Acquires Two More Important Diamonds

LONDON, November 25, 2010 - Just days after the historical purchase of the world's 'finest pink
diamond', the 'Graff Pink', Laurence Graff is pleased to announce the
acquisition of two more important stones. The 196 carat and 184 carat rough
diamonds were successfully acquired for a total of $22,736,360 during a
sealed-bid tender in Antwerp yesterday.

The diamonds, recovered from the Letseng mine in Lesotho in the second
half of 2010, are the latest purchases in an impressive roll call and mark
Laurence Graff and the South African Diamond Corporation as the leading
investors of significant stones sourced from the famous African mine and
further establish Laurence Graff as the world's leading Diamantaire.

The Letseng mine, based in the Maluti Mountains in Lesotho, is a mine of
growing significance, having produced three of the world's top 20 diamonds
ever discovered. This is Graff's fifth significant purchase of a notable
Letseng diamond in recent years and follows other notable stones, such as the
603 carat 'Lesotho Promise', the 493 carat 'Letseng Legacy' and the most
recent acquisition - the 478 carat 'Light of Letseng', which was then
polished to reveal the Graff Constellation, the world's first round,
brilliant, flawless diamond to exceed 100 carats.

Laurence Graff, founder and Chairman of Graff Diamonds Holdings comments:
'We are delighted with the successful acquisition of these two major stones.
This purchase further demonstrates our continuing investment in the industry
and the world's finest diamonds. We look forward to the challenge of cutting
and polishing these stones and releasing their full potential.'
