The Graff Venus was deemed the largest D Flawless heart-shaped diamond in the world when it was unveiled in 2016. It took craftsmen 18 months to cut and polish the Type IIA diamond from a 357-carat, rough diamond that was discovered in 2015 at the Letseng Mine in Lesotho.

Founder Laurence Graff bought the bewitching Wittelsbach diamond at Christie’s in December 2008 for a little more than Dh60 million, the highest price ever paid for a gemstone at an auction at the time. He had his master cutters give the stone a modern polish with additional facets to highlight its blue colour, which reduced its weight by about four carats to 31.06, and it was renamed the Wittelsbach-Graff diamond.

Natural pink diamonds are the rarest gems in the world. The Graff Pink weighs 23.88 carats, and has a rectangular step-cut and delicate round corners. Between 2010 and 2017, the stone held the world auction record for a pink diamond, at a price of Dh169 million. Courtesy Graff
