Historic Victory Diamond Highlights Sotheby’s Auction


Sotheby’s Geneva auction of Magnificent Jewels and Nobel Jewels next month has a number of stones that are sure to sell in the millions.   For history buffs, the first on that list is the stunning Victory Diamond.

The Victory Diamond was the largest of 30 diamonds cut out of the rough the 770-carat Woyie River diamond.   Found in Sierra Leone in 1945, the lozenge-shaped Woyie River diamond was the the third largest diamond ever found in Africa.

Named in honour of the Allied victory during World War II, the Victory Diamond is a potentially flawless, type IIa, step-cut 31.35 carat stone that should sell at the auction for between $5 and $8 million.

Also expecting to make headlines at the same auction is a couple of diamonds from the London-based jeweller Graff Diamonds. The first is the Graff Vivid Yellow diamond.   Weighing in at 100.09 carats, it is considered the largest fancy vivid yellow diamonds ever recovered.   The diamond, described as “daffodil yellow” in colour has a hefty auction pre-sale estimate at between $15 and $25 million.   However, with the value of colour diamonds continuing to increase, some of our in-house experts believe that estimate could be a little conservative.

The other major diamond to go under the hammer from Graff is a 103.46 carat, brilliant-cut, round stone.   Many experts consider the gem to be one of the largest known round diamonds. The stone is expected to sell at auction for between $3.5 to 5 million.


Two Of Christie’s 2014 Magnificent Jewels

Christie’s, the famous New York City auction house, is holding their annual Magnificent Jewels auction on April 16. Always a highlights of the spring calendar in the diamond world, last year’s auction featured a 34.65 carat Fancy Intense Pink diamond that ended up selling for $39.3 million.

The high end pieces for this year’s auction include a pair of Internally Flawless diamond ear pendants of over 22 carats each, a 40.43 carat oval-cut diamond and a 50.05 carat Flawless briolette diamond.  However, a couple of sparkling colour diamond pieces by JAR really caught our eye.

1.  Historic Fancy Yellowish Green Diamond


Three separate angles of a 2.49 carat fancy yellowish green diamond set with an old-mine cut surround with a single-cut diamond gallery and hoop, mounted on platinum.   Early estimates are that this could sell for as high as half a million dollars. The diamond itself was formerly owned by Eliza Branicka, the wife of 18th century Polish romantic poet Zygmunt Krasinski.

2.  Oval-Cut Fancy Intense Yellow Diamond


A 15.75 carat oval-cut, fancy intense yellow diamond set on a pave diamond thread mount and mounted on platinum.   Christie’s estimates that it should sell between $500,000 and $700,000. The piece was formerly the property of Brazilian philanthropist and socialite Lily Safra.   One of the richest women in the world, Safra owns what is considered the second most expensive home in the world Villa Leopolda on the French Riviera.

Jewels by JAR

What makes these two colour diamond pieces even more special is that they are from jeweller Joel Arthur Rosenthal, better known simply as JAR.   His shop, located in Paris’ Place Vendôme, has no windows, no signage and no set hours.   He caters only to the worlds’ elite and does so without advertising or a social media presence.  The mere mention of his name means that what Christie’s estimates for these two colour diamond rings could end up being a very conservative guess.

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.
