Christie’s claims to be auctioning off the world’s largest flawless diamond on May 15th at the Magnificent Jewels auction in Geneva. Weighing 101.73cts, this D color, type IIA flawless pear-shaped diamond. Conceived in the Jwaneng Mine, Botswana and emerging from 236cts of rough, this impressive pear-shaped diamond took all of 21 months to polish.
In terms of rarity, consider the fact that annual worldwide diamond production is in excess of 100 million carats. Since GIA estimates a maximum of 600 rough diamonds between one and two carats graded D / flawless polished annually, diamonds over ten carats exponentially decline in availability, leaving stones of this caliber and weight almost priceless. However, if you are in the market for a large pear-shape diamond that is too big to wear on your finger, an estimate is available upon request.
