The largest blue-green diamond ever sold also became the most expensive when it fetched a world record for a stone of its hue at Christie’s in Geneva, bringing in CHF 13.6 million ($17.4 million).
The stone, called the Ocean Dream, is a triangular-cut, 5.50-carat, fancy-vivid-blue-green type IIa diamond, which originated from an 11.70-carat rough discovered in Central Africa in the 1990s. Set in a ring, the piece generated “intense bidding” for 20 minutes, soaring past its CHF 10 million ($12.8 million) high estimate. In total, the May 13 Magnificent Jewels sale fetched CHF 51.9 million ($66.5 million), the auction house said Wednesday.
Of the 87 lots on offer at the auction, 84% sold above their high estimates, with 13 realizing over $1 million. About 40% of participants at the sale hailed from Europe, while 27% came from the Americas and 28% from Asia Pacific.
