The first record-setting diamond from this week was a 16.08-carat Fancy Vivid pink diamond that went under the hammer at Christie’s Geneva Magnificent Jewels sale on Tuesday, November 10.

The cushion-shaped stone, now called “The Sweet Josephine” is one of only three Vivid pink diamonds weighing over 10 carats ever to go to auction.   The final sale price did not disappoint as the diamond sold for more than $28.5 million, an auction record for a Vivid pink diamond.

The jaw-dropping numbers continued on Wednesday, November 11, as a 12.03-carat Fancy Vivid blue diamond set a world record for any gemstone sold at auction in history as well as the largest per-carat price for a gem in history.

The Blue Moon Diamond, now called “The Blue Moon of Josephine”, was part of the Sotheby’s Magnificent Jewels and Noble Jewels auction  in Geneva.

Numerous sources have confirmed that the buyer of both diamonds was Hong Kong real estate developer Joseph Lau.   The billionaire is listed by Forbes Magazine as the 114th richest person in the world.   He named both diamonds after his 7-year old daughter Josephine.

A Possible Record-Breaking Diamond

A 12.03-carat Internally Flawless Fancy Vivid Blue diamond could become a record-breaking stone come this November as it goes to auction by Sotheby’s.

The “Blue Moon Diamond”, named for its once-in-a-blue-moon kind of rarity is expected to sell for between $35 and $55 million at their Magnificent Jewels and Noble Jewels auction in Geneva.

The original stone was recovered by Petra Diamonds at the Cullinan mine in South Africa in January 2014.

In it’s original state, it weighed in at 29.62-carats and was quickly sold for $25.6 million to Cora International.   The New York-based firm then spent the next 6 months cutting and polishing the fabulous blue stone to its current form.

If the Blue Moon Diamond does end up selling for more than $32.6 million, it will break the record currently held by the 9.75-carat Zoe Diamond as the most expensive blue diamond ever sold.  If it sells for more than $46.2 million, it will set the record for the most expensive diamond of any kind sold at auction.
