12 Nov 2008

Gem Diamonds Limited (LSE: GEMD) welcomes the announcement of Graff Diamonds' acquisition of 4.5% of the Company which Graff alerted the Company to on November the 11th, 2008.

The two companies have enjoyed a strong relationship over the two years since Gem Diamonds acquired its majority stake in Letšeng Diamonds. Over this time Graff has grown to be one of Letšeng's key clients, having acquired both the Lesotho Promise and the Letšeng Legacy diamonds, amongst other important diamonds.

Gem Diamonds and Graff share a focus on the top end of the diamond market, a sector of the market that has shown itself to be relatively resilient in times of economic downturn.

Commenting on the announcement, Clifford Elphick CEO of Gem Diamonds said:

"Gem Diamonds looks forward to further developing its relationship with Graff, now as a shareholder as well as key client, and acknowledges the vote of confidence that this investment in Gem Diamonds represents."
