The “Perfect Diamond” Goes Up For Auction

Sothebys-NY_100-ct-DIF-Diamond

A stunning 100-carat emerald-cut white diamond headlines Sotheby’s Magnificent Jewels auction coming up this April.   The stone, recovered a year ago in the mines of South Africa, weighed in at 200 carats in its rough form.

Diamond giant DeBeers spent a year studying, cutting and polishing the rare stone before a world tour that includes Hong Kong, Dubai and London before ending in New York City for the big sale.

Gary Schuler, the head of Sotheby’s jewelry department in New York, said the diamond “is the definition of perfection. The color is whiter than white, it is free of any internal imperfections.”

The cut of the diamond is what has most people talking.   According to Mr. Schuler, “It is the first true emerald-cut diamond over 100 carats to be offered at auction – the most classic of cuts, quietly elegant and very contemporary.”

The diamond is expected to sell for between $19 and $25 million.   Those prices break down to a per-carat price of between $189,000 and $249,000.   Two similar quality white diamonds of that size sold at auction in 2013 for $263,000 per carat and $259,000 per carat respectively.

A Pear-Shaped Light Pink Diamond featuring white diamond shoulders is the final entry on the list.   The low-end estimate for the piece is $783,000 though, considering the rarity of pink diamonds, the sale price will probably end up closer to the top-end of the estimate $1.6 million.

5 Highlights of Sotheby’s Magnificent Jewels Auction

On April 7, Sotheby’s Hong Kong will be hosting their Magnificent Jewels And Jadeite Auction.   The early estimates look like sales of all of the pieces could reach close to $100 million.   A trio of necklaces appear to be getting all the early headlines.  However, our list focuses on the colour diamonds that will be featured in the auction.

The “Pink Star” Diamond Buyer Defaults On Record Purchase

pink star

The world’s most famous pink diamond is, once again, searching for an owner after news came out Friday that the original auction bidder is not going to be able to complete the purchase.

The Pink Star, a 59.6 carat flawless oval cut pink diamond, is the largest internally flawless fancy vivid pink diamond ever graded by the Gemological Institute of America.   It was originally mined by De Beers in 1999 in South Africa and weighed 132.5 carats in the rough.

Famed auction house Sotheby’s put the diamond on the block last November as part of their Magnificent Jewels auction.  There was a brisk five-minute bidding war for the stone and was eventually won by New York City diamond cutter Isaac Wolf.   The price for the stone ended up being $83.02 million, the highest auction selling price for a diamond ever.

In a conference call on Thursday, February 27, Sotheby’s said that they had to take the diamond back into their own inventory as the buyer had defaulted on the purchase.   The stone is currently listed with a value of $72 million.

“We are currently in discussions with the buyer, while also considering other alternatives,” Patrick McClymont, Sotheby’s CFO said on the call. “In the meantime, we are quite comfortable with our valuation, and see real value in owning the diamond at this price.”

Considering the Pink Star was originally estimated to sell at auction for around $61 million just five months ago, it looks like the colour diamond industry is still booming.
