On May 13, Sotheby’s Geneva will auction the 100.9 ct. Graff Vivid Yellow, considered among the largest fancy vivid yellow diamonds in the world.
The stone, named for famed London diamond collector Laurence Graff, is described by the auction house as “of exceptional beauty and extraordinary fire and brilliance” with a “sensational daffodil yellow” color.
It carries a $15 million to $20 million estimate.
Also being sold is a Graff diamond ring, below, which features a 103.46 ct. round brilliant cut, considered among the largest known round diamonds.
It carries a $3.5 million to $5 million estimate.
Also part of the Magnificent Jewels and Noble Jewels sale is the Victory Diamond, below, a 31.34 ct. D Type IIa step cut, named in honor of the Allies’ triumph in World War II. The original rough was discovered in 1945 and was then the largest alluvial rough ever found, weighing 770 cts. In the early 1950s, 30 diamonds were cut from that rough, with the Victory Diamond being the largest.
The diamond is considered potentially flawless. It carries a $5 million to $8 million estimate.
