A stinking rich buyer has christened this $28.55-million purchase the Sweet Josephine. And so sets a Christie’s record for pink diamonds, this one described as the “largest cushion-shaped fancy vivid pink diamond ever to be offered at auction.” The November 10 winning bid brought over half a million more than the highest anticipated price and nearly tripled the auctioneer’s past pink record of $10.77 million set in 2009.
In 2010 rival Sotheby’s sold a 24.78-carat pink for $46 million.
The 16.08-carat stone comes set in a ring and “surrounded by a double row of pavé white diamonds, highlighting the main stone, with a third row of small pink diamonds underneath,” Christie’s stated. “The band is comprised of small circular-cut white diamonds set in platinum.”
Among coloured diamonds, pinks are the most coveted and regularly fetch record prices, the auctioneer explained. But with no trace of a secondary colour, this one’s exceptionally rare. “Only one in 100,000 diamonds possesses a colour deep enough to qualify as ‘fancy’.”
Size matters too. Less than 10% of pinks weigh more than one-fifth of a carat. “In almost 250 years of auction history, only three pure vivid pink diamonds of over 10 carats have appeared for sale,” Christie’s added.
The stone “comes to market at a time when great gems are mirroring prices achieved for masterpieces in the world of fine art,” said Christie’s spokesperson Rahul Kadakia prior to the auction. “Collectors are looking to jewels as savvy investments that are both beautiful and can appreciate considerably in value over a relatively short period of time.”
Rio Tinto’s (NYE:RIO) Argyle mine in Western Australia claims credit for most of the world’s rare pinks and reds. The same day the Sweet Josephine changed hands, Rio’s 2015 Pink Diamonds Tender “delivered an exceptional result, reflecting global demand and sustained price growth,” the company stated. But prices were confidential. Rio plans to suspend Argyle’s operations sometime this quarter.
Sotheby’s hopes to soar past the record-selling pink the evening of November 12, when the final lot of its Geneva auction comes up for bids. The 12.03-carat, internally flawless Blue Moon has been described as one of the world’s rarest gems, with a fancy vivid hue that “might be so unique as to be indescribable.”
This billion-year-old chunk of carbon from Petra Diamonds’ Cullinan mine in South Africa could bag $35 million to $55 million.
