Sotheby’s Upcoming Geneva Auction Will Not Disappoint Diamond Investors

In just 2 weeks’ time, Sotheby’s will break another record, by showcasing the largest recorded Fancy Intense Pink diamond in the world, the Raj Pink diamond. In addition, they will be showcasing a magnificent Fancy Vivid Blue diamond by luxury jewelers Moussaieff, as well as a historic pair of Fancy Intense Yellow diamonds called the Donnersmarck Diamonds, and a superb pink diamond by beloved American jeweler Harry Winston.


The Raj Pink Diamond

The world’s largest recorded Fancy Intense Pink diamond will go under the hammer at Sotheby’s much anticipated upcoming November auction in Geneva. This will be the final auction for them of the Fall sessions of auctions, and it is showcasing some of the best jewels of the year. At 37.30 carats, this Fancy Intense Pink diamond is almost 3 carats larger than the previous largest Fancy Intense Pink ever to be auctioned, the 34.65 carat Fancy Intense Pink “Princie Diamond”. The Princie Diamond is the previous largest Fancy Intense Pink diamond ever sold, but it does not hold the record price paid for a Fancy Intense Pink diamond. that record is still held by the 24.78 carat Fancy Intense Pink “Graff Pink” diamond, which was sold on November 16, 2010 for a then, and still record of $46.16 million in total, or $1.862 million per carat. The Graff Pink still holds both record for any Fancy Intense Pink sold at auction over 10 carats.

The Raj Pink diamond is estimated to sell at the Sotheby’s auction at a price between $20 million and $30 million, or for $538k to $807k per carat. This seems to be a conservative figure for such a large and rare diamond, but there are several factors to consider in order to reconcile their price estimate. The most prominent factor that is influencing the price is the color. The diamond does not display an especially strong color for a Fancy Intense Pink color grade, and this will definitely affect the value. The Raj Pink is closer to a strong Fancy Pink color grade, which justifies the valuation.

Moussaieff Fancy Vivid Blue Diamond

Once again, Moussaieff will be offering an incredible diamond, this time a Fancy Vivid Blue diamond with Internally Flawless clarity, a true rarity. In recent years, Moussaieff has been offering a blue diamond at auction annually, each time a Fancy Vivid Blue but in different carat weights. This additional blue diamond proves that they own yet another high quality blue diamond, and that they have a very exceptional ability to acquire high caliber diamonds. It also serves as a statement on their part that they are able to offer blue diamonds like these that other jewelers are not.

At 7.41 carats, this is the remarkable blue diamond of the evening, and possibly of the entire year. From its Oval Modified Brilliant shape, we can deduce that most likely, this diamond was at one time a marquise shape, and most likely an inferior clarity than it is now that it was probably re-polished. Moussaieff, as always, has been able to bring out the exceptional color and clarity of the diamond when it was recut into this shape.

The 7.41 carat Fancy Vivid Blue Moussaieff diamond is valued at a price between $14 million to $18 million, or $1.9 million to $2.4 million. In my opinion, this price is a true bargain for this diamond, even if it sells at the high end of its valuation. I do not expect this diamond to break a record price when it sells, but I do believe we will see a much stronger price than what the auction house is expecting once the hammer goes down.

The Donnersmarck Diamonds

The famous pair of Fancy Intense Yellow diamonds once belonging to the Countess von Donnersmarck is once again being offered on the market. They were previously offered by Sotheby’s at a 2007 auction as separate lots, and this time, they are being offered together. This will ensure they would not separate from each other, which is important because of their provenance. The diamonds are 102.54 carats and SI1 clarity, and 82.47 carats with VS2 clarity.

Together, they are estimated to be valued at $9 million to $14 million, or $49k to $76k per carat. If it was not for their important provenance, I would say that they are way over valued, even though they are unique in size. One must carefully view the color depth, and clarity when determining a diamond’s value, and in this case neither quality is significant for either diamond. It is the provenance that will most likely sell this pair.

Harry Winston Pink Diamond

Harry Winston diamonds always perform well at auctions, and the expectation is that this pink diamond will behave similarly. This wonderful Fancy Light Pink diamonds weighs 33.63 carats and has a VVS1 clarity.

It is valued at $8.1 million to $14 million by Sotheby’s, or $241k to $418k per carat, a valuation that is quite high. If it ends up selling, it will break several records. It is not the largest Fancy Light Pink to ever be sold at auction. That record is held by a 40.30 carat Fancy Light Pink diamond with VVS2 clarity that was sold on November 16, 2016 at Sotheby’s Geneva auction. If it sells, the Harry Winston diamond will break the record for the most expensive Fancy Light Pink ever to sell at auction in total value as well as per carat value. The only way that I see this diamond selling anywhere close to the top end of the value is if it has a strong potential of an upgrade via re-polish into a Fancy Pink, and if it remains above 30 carats after the recut. It may also get an IF clarity should that happen. In that case only would we see the diamond sold at such a significant price.
