Sourcing
Graff adheres to the Kimberly process, never knowingly buying or trading rough diamonds from areas where this would encourage conflict or human suffering. The majority of Graff diamonds are laser engraved with unique Gemological Institute of America tracking numbers, which whilst invisible to the naked eye, allow for their origin to be traced.
Notable diamonds
The Windsor Yellows were acquired by Laurence Graff in 1987 in Geneva during the auction of the jewels belonging to Wallis Simpson, Duchess of Windsor. The Duchess was often photographed wearing the Windsor Yellows, a pair of clips of fancy yellow pear shaped diamonds of 51.01 and 40.22 carats respectively. "I also bought another pair of clips the Duchess had owned," Laurence Graff explains. "Of course they needed re-cutting to bring them to their full potential, I bought all four, repolished them, and eventually made the Windsor earrings."
The Paragon diamond was acquired by Graff in 1989. The Paragon is a 7-sided diamond of 137.82 carats (27.564 g), cut, and was worn as part of "millennium" necklace of round, pink, blue and yellow diamonds by Naomi Campbell in 1999.
The Lesotho Promise was acquired as a rough 603-carat (120.6 g) stone for $12.4 million in 2006. The stone was cut by a team of 35 using computer-controlled lasers into 26 D-flawless diamonds totaling 223.35 carats (44.670 g), the highest yield from a single diamond. In July 2007 the finished stones were unveiled. The largest gem cut from the diamond was a 75-carat (15.0 g) pear-shaped diamond; the smallest a 0.55-carat (110 mg) round brilliant. In all, twenty-six stones were fashioned from the rough gem, figuring as seven pear shapes, four emerald cuts, thirteen round brilliants and one heart shape. The finished gems total 224 carats (44.8 g).
The Letseng Legacy diamond was unearthed from the same mine as the Lesotho Promise Letseng diamond mine in 2008 and totalled 493cts. Acquired by Graff for $10.4 million, they yielded 20 diamonds totaling 231.67cts from the one rough stone.
The Wittelsbach-Graff Diamond is a 31.06-carat (6.212 g) fancy deep-blue diamond with internally flawless clarity purchased by Laurence Graff in 2008 for £16.4 million.
The Delaire Sunrise is, at 118.08 carats, the largest square emerald cut Fancy Vivid Yellow diamond in the world. Discovered in 2008 at an alluvial mine in South Africa, the 221.81 carat rough diamond. When Laurence Graff unveiled the finished diamond, he named it "the Delaire Sunrise".
The Constellation is, at 102.79 carats, the largest round shaped, D colour, Internally Flawless diamond ever to be graded by the Gemological Institute of America.
The Graff Pink was acquired by Graff in November 2010. A pink diamond with a type IIa classification and modified emerald cut shape, the diamond was previously held in a private collection for over 60 years. The diamond displayed 25 natural flaws. The recut 23.88 carat diamond displayed new colour, clarity and internal flawlessness.
The Graff Sweethearts were originally two rough diamonds weighing 196 carats and 184 carats discovered at the Letseng Mine in Lesotho. After cutting they produced a 51.53ct D colour Flawless type IIa and a 50.76ct D colour Flawless type IIa, both heart-shaped.
The Sultan Abdul Hamid II is a 70, 54 carat light yellow acquired by Graff in 1981. It has been suggested that this stone may have been cut from "The Ottoman I" which originally belonged to Suleyman the Magnificent of Turkey.
