Geneva (AFP) - A spectacular and rare orange diamond, the largest known gem of its kind, was auctioned for a record $35.54 million in Geneva.
"It's a world record price for an orange diamond, it's a world record price per carat for any coloured diamond," the Christie's auction house said of the sale, on Tuesday.
"It's a tremendous price, a magnificent price," it added, likening the purchase of such a prized coloured diamond to buying a Picasso or Van Gogh painting.The price works out at $2.4 million per carat, beating the previous record of $2.15 million for the Vivid Pink Diamond sold in Hong Kong in 2009.
"At the back of the hall, 29 million francs ($31.5 million, 23 million euros). Sold!" the Christie's auctioneer said as the fiery almond-shaped gem was snapped up in a room of about 200 people in a luxury Geneva hotel.
The total sale price was boosted by another $4.04 million in taxes and commission.
The man who made the purchase swiftly got up and left the room to a round of applause. Christie's did not reveal his identity.
The deep orange gemstone, found in South Africa, weighs a whopping 14.82 carats. The Gemological Institute of America (GIA) has handed it the top rating for coloured diamonds: "fancy vivid".
Pure orange diamonds, also known as "fire diamonds", are extremely uncommon and few have been auctioned, with the largest never more than six carats."To have one that’s over 14 carats is exceptional," Christie's international jewellery director David Warren told AFP. He said "The Orange" was "the largest recorded vivid orange diamond in the world".
In 1990, the 4.77-carat yellow-orange Graff Orange diamond was sold for $3.92 million and in 1997 the vivid orange Pumpkin diamond of 5.54 carats was sold for $1.32 million.
Christie's had estimated "The Orange" would rake in $17 million to $20 million.
Coloured diamonds, once considered a curiosity, are rarer than white diamonds and today attract higher prices per carat than even the most flawless, translucent stone.
That, Warren explained, was because, "coloured diamonds are real freaks of nature. They begin as white diamonds, and it’s some accidental colouring agent in the ground that will turn it a particular colour".
Green diamonds, for instance, are coloured by radioactivity in the ground, blue diamonds get their colour from boron, and yellow diamonds, which in rare cases turn orange, are coloured by nitrogen.
Pink diamonds get their colour from a distortion in the crystal lattice as the stone is taking shape.
Coloured diamonds "are extraordinarily rare stones," agreed David Bennett, who heads the European jewellery division at Sotheby's.
Christie's rival is set to auction a flawless 59.60-carat vivid pink diamond, called "The Pink Star", in Geneva on Wednesday, with an asking price of $60 million.
Like "The Orange", the plum-sized shimmering "Pink Star" has received the highest possible colour rating from GIA, as well as top marks for clarity.It is also the largest of its kind, Bennett said, insisting the anonymous seller was not asking too much.
"Very, very few of these stones have ever appeared at auction and three years ago, a five-carat vivid pink made over $10 million. So the estimate on this stone of $60 million would appear to be very reasonable,” he told AFP.
For those who cannot cough up that kind of money, both Christie's and Sotheby's "Magnificent Jewels" auctions also offer a range of other items of historic importance but with lighter price-tags.
A shimmering emerald and diamond necklace by Cartier that has been in the collection of Bolivian tycoon Simon Iturri Patino since he bought it for his wife in 1938 raked in almost $10 million on Tuesday evening. LINK
