The oval-shaped, 10.10-carat, fancy vivid blue, internally flawless gem fetched $3.2 million per carat, according to a Sotheby’s statement April 5. The sale comes amid strong interest in valuable colored diamonds with recent auctioneers’ estimates of up to $45 million for large stones.
The gem (pictured) is sourced from an Asian private collection and is the only oval-shaped precious stone among 12 rare diamonds – eleven blue and one colorless – in the De Beers Millennium Jewels collection unveiled in 2000 to celebrate the turn of the century.
In total, the auctioneer’s Magnificent Jewels and Jadeite auction on April 5 sold $73.3 million of jewels, or 65.7 percent by lots and 69.3 percent by value. A 22.40-carat, D-color, internally flawless diamond ring sold for $3.7 million and four other items fetched more than $2 million, including a jadeite and diamond ring and pair of matching earrings and a 4.08-carat fancy vivid orange diamond and diamond ring.
“Rare and important jewels from Asian private collections lead the strength of the market, with the De Beers Millennium Jewel 4, the fancy vivid orange diamond and the strand of natural pearls achieving exceptional prices,” said Quek Chin Yeow, deputy chairman of Sotheby’s Asia and chairman of International jewelry for Asia.
