This 101.73ct diamond is destining to set another record for Christies. On May 15th, Christies Geneva will auction off a 101.73ct pear shape D Flawless, which is the largest D-flawless ever to be up for sale and it is also one of the largest pear shape diamonds known to exist.

Flawless Diamond

The diamond is also a rare Type IIa, which makes up less than 2 percent of the world's diamond production. Type IIa diamonds are almost or entirely free of impurities, and therefore are usually colourless. Type IIa diamonds are very rare in nature, and have enhanced optical and thermal properties. Many large famous diamonds, e.g. Cullinan and Koh-i-Noor diamonds are Type IIa diamonds.

The stone is expected to fetch $20 million–$30 million, says François Curiel, the auction house's international head of jewelry.

'This is the largest D-flawless ever to appear for sale at auction and also the most perfect drop to come up on the auction block," he says. "We expect tremendous interest, not just from high-profile members of the trade but from top private collectors too.'

The diamond comes from a 236 ct. rough that was found at the De Beers–owned Jwaneng mine in Botswana and took 21 months to polish, Christie's said.

Christie's declined to identify the seller of the stone. De Beers says the stone came from one of its sightholders, but declined to identify the company.

Christie's release includes a list of world record prices for diamonds at auction, and it clearly expects the stone to join that pantheon.

The Archduke Joseph Diamond set the current auction record for a colorless diamond when it sold for $21 million at Christie's Geneva in November 2012.

While this gem is by any standard an amazing diamond, it is not the largest D-flawless known to exist. It is smaller than the 273.5 ct. De Beers Centenary, as well as the 203.4 ct. pear-shape Millennium Star.
