Bleu Royal

17 Oct 2023

Christie’s to present in Geneva in November the Bleu Royal, the largest internally flawless fancy vivid blue diamond to appear at auction

Bleu Royal will be the leading highlight of the upcoming Magnificent Jewels auction on 07 November at Christie’s Geneva. Weighing 17.61 carats, Bleu Royal is the largest Internally Flawless Fancy Vivid Blue gem ever to appear for sale in auction history.

Cut and polished into a perfectly symmetrical pear combined with a rich vivid blue colour and flawless purity, this diamond is amongst the rarest to have been unearthed (estimate US$35–50 Million). Bleu Royal has remained part of an important private collection for the past 50 years. This is the first time the stone, set in a ring, will be presented for sale at auction.

This is a true miracle of nature,” Rahul Kadakia, Christie’s International Head of Jewellery, comments. “Over our 257-year long history Christie’s has had the privilege of offering the world’s rarest gems at auction, and Bleu Royal continues this tradition. We are proud to offer collectors the opportunity to own a diamond fit for Royalty.”

Driven by collector demand and an increasingly limited supply, prices for top-quality colored diamonds have increased exponentially in recent years. In the saleroom, Fancy Vivid Blue diamonds over 10 carats are virtually unheard of — in more than 250 years of auction history at Christie’s, only three such stones have ever appeared for sale.
