A “Stamp Sized” Pink Diamond Could Set A Record

150924_pink_diamond_660

The largest diamond of its kind is set to go to auction later this year and the sales price could be as high as $28 million.

The 16.08-carat diamond will be the highlight of Christie’s Magnificent Jewels auction in Geneva coming up on November 10.

The Fancy Vivid Pink diamond is described as “stamp-sized” and is the largest Fancy Vivid Pink diamond ever sold at auction.

“The fancy vivid pink grading means the hue is of the purest and strongest saturation,” said Rahul Kadakia, Christie’s head of jewelry.

“The color is even and shows no trace of a secondary color that may include purple, orange brown or grey in pink diamonds of a lower grade.”

The pre-auction estimate for the diamond has been set for between $23 and $28 million (USD).   The current per-carat record price for a pink diamond is $2.1 million.   To break that record, this diamond would need to sell for at least $33,768,000.   Considering that amount is only $5 million above the high-end estimate, it is possible that this record could fall.

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.
