Largest Oval Fancy Vivid Blue Diamond to Be Sold at Auction

When talking diamond size, specifically in regards to fancy color diamonds, there is the 'largest stone' category, and then there is the 'largest stone ever to be auctioned' category. Sometimes, they are one and the same, while other times, what may be the largest stone of that specific type on the planet can also be different from the largest diamond of the same color, put up for auction. For instance, at 13.22 carats, the “Winston Blue,” previously dubbed “The Blue,” is the world's largest flawless blue diamond. However, the largest blue diamond ever to be auctioned is the Blue Moon diamond, a12.03-carat fancy vivid blue diamond. In the oval fancy vivid blue diamond category, the largest diamond and the largest diamond to be put up for auction are indeed one and the same. This exceptionally rare gem will be auctioned on April 5 in Hong Kong, at the Sotheby's Magnificent Jewels and Jadeite spring sale.



The Diamond

At 10.1 carats, the oval internally flawless vivid blue diamond is the largest of its kind and the largest to be sold at auction. The jewel is part of the De Beers Millennial Collection that was created in 2000, which includes twelve diamonds. There is one colorless and eleven blue diamonds in the collection. All of the blue diamonds originate from the Cullinan Mine in South Africa. Only one out of all of those diamonds was ever offered to the public until now. This was the 5.16-carat internally flawless pear-shaped fancy vivid blue diamond, which Sotheby's Hong Kong sold in 2010. It was dubbed the “De Beers Millennial Jewel 11.”

This incredible record-breaking diamond is just one of twelve remarkable stones that were collected over decades in order to celebrate the new millennium. The unique collection was the initiative of De Beers and the Steinmetz Group. The largest stone in the group is the 203.04-carat colorless diamond named the “Millennium Star.” All but two of the blue diamonds are classified by the GIA as fancy vivid blue diamonds, the highest color grade for blue diamonds.


Blue Diamonds

Fancy color diamonds are extremely rare and only account for 1 out of every 10,000 diamonds mined. However, blue diamonds are amongst the rarest of all color diamonds. In fact, they are so rare that only 0.1% of the diamonds mined at the Cullinan Mine are blue diamonds. That means that the annual discovery of one blue diamond is still considered a rare occurrence.

The rarity of this stone coupled with the beauty of the natural blue coloring, which is caused by the presence of boron in the diamond, results in an impossibly high demand and staggering prices. Those lucky enough to get their hands on one generally end up with a very small and somewhat included stone. This just goes to show how unbelievably scarce and unique this oval blue diamond is and why it is believed to fetch between $30 million and $35 million.

Blue diamonds are amongst the few specimens in the world worth keeping tabs on. This is because the numbers of blue diamonds, as well as many diamonds in general, are dwindling, so every significant find holds immense importance and has the potential of making history with its sale as well as with its auction process.
