Entirely paved with diamonds, a ring set with an exceptional old-cushioned Kashmir sapphire weighing 18.42 carats was auctioned for €1,110,000 (excluding costs), against a low estimate of €800,000.

No strike for the auctions at the Hôtel des ventes de Monte-Carlo but still some traffic jams to report to the hammer of its president and expert, Franck Baille, in recent days. Not surprisingly, the peak of interest of international collectors focused on lot 400 of the gemstone catalogue concocted by gemmology expert Chantal Beauvois.

“A SOURCE OF SAPPHIRES THAT HAS BECOME LEGENDARY”

Entirely paved with diamonds, a ring set with an exceptional old-cushioned Kashmir sapphire weighing 18.42 carats was auctioned for €1,110,000 (excluding costs), against a low estimate of €800,000.

To grasp the rarity of this pure blue gem, it was necessary to immerse yourself in the certificate of the Gübelin laboratory in the appendix.

“The island of Ceylon was the world’s leading source of sapphires and for centuries remained the supplier of these gem-quality stones. As with rubies, the remote Mogok Valley in Myanmar has become a primary source of high-quality sapphires. However, the most important event in the history of sapphire took place in the early 1880s. A landslide in the Himalayan mountains of Kashmir revealed a source of sapphires that has become legendary for the quality of its stones. The very special soft blue colour of Kashmir sapphires forges their identity, it is highly sought after by connoisseurs and collectors.”
