Sotheby's to Auction the Largest Untreated Paraíba Tourmaline

On September 17, 2026, at 2:00 AM EDT, Sotheby's in Hong Kong will host a live auction showcasing an extraordinary pair of untreated Paraíba tourmalines. Dubbed the 'Kat Florence Luminas,' this remarkable set is poised to set a world record due to its unmatched size and quality. The tourmalines, artfully crafted by renowned jeweler Kat Florence, weigh in at an astonishing 71.239 and 72.844 carats respectively, making them the largest flawless tourmalines ever to be auctioned.

The original material was unearthed in 2003 by Don Kogen, a renowned gem hunter and member of the Kat Florence Atelier, during an expedition in Mavuco, Mozambique. The initial crystal weighed about 830 carats, showcasing the potential that this rare gemstone holds.

World-Class Certification and Recognition

Recently, the pair received an 'Outstanding' grade from the Gübelin Gem Laboratory, coupled with an impressive score of 92.1 points. On June 19, 2026, the Bellerophon gemological lab also inspected the pair and honored them with the Bellerophon Privilege Award, a recognition given to an extremely rare find. Martial Curti, the CEO and founder of Bellerophon Gemlab, emphasized the significance of owning such natural Paraíba tourmalines,

“These magnificent stones are extraordinary in both size and quality, representing a truly rare find.”

This auction is not a first for Kat Florence; it marks her ninth record-breaking piece to hit the auction block. Alongside the stunning tourmalines, another breathtaking creation, a flawless 424.80-carat tanzanite necklace adorned with diamonds, will also be auctioned on the same day. The tanzanite was analyzed by Gübelin Gem Lab and awarded an 'Outstanding' rating, with an unprecedented score of 91.9, highlighting Kat's dedication to perfection and artistry.

Kat Florence is not just a jeweler; she also owns the Kat Florence Hotel in Canada, which serves as an exclusive retreat for her VIP clients. Inside the hotel, guests can marvel at a rotating collection of her extraordinary gems, displayed against the original limestone walls of the historic building. This collection includes the world's largest flawless untreated Paraíba tourmaline and the unprecedented tanzanite pendant necklace. Unlike traditional museums, the hotel setting transforms these priceless gems into part of an immersive experience.
