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.
