Graff Unveil Lesotho Promise Diamonds

The stunning Lesotho Promise diamond found last year by Gem Diamonds has been unveiled in a different guise at Graff, based in Knightsbridge, London.


The Lesotho Promise is ranked as the 15th biggest diamond ever found and weighs in at a hefty 603 carats. It has been carved up to form a stunning collection of 26 flawless diamonds.

Graff purchased the stone at auction for £6 million ($12 million). The cut stones are expected to sell for double that.
