Sotheby s auctions world largest flawless unheated Paraiba tourmaline gem pair
Sotheby s Hong Kong scheduled a live September 17 auction for the Kat Florence Luminas the world s largest matched pair of unheated flawless Paraiba tourmalines
On September 5, 2026, Sotheby's Hong Kong announced it would auction the world's largest flawless Paraiba tourmaline gems, a pair known as the Kat Florence Lumina matched pair, during its High Jewelry event on September 17, 2026. The pair, crafted by renowned artist Kat Florence, each weighs between 71.239 and 72.844 carats, making them the largest of their kind ever to go to auction.
The gemstones were discovered in Mozambique in 2003 by gem hunter Don Kogen and later evaluated by Swiss lab Gübelin and French lab Bellerophon, both of which awarded the pair top scores for their exceptional quality, size, color, clarity, and cut. The gemstones are part of Florence's ongoing quest for record-breaking perfection in her artistic work, with her previous unmatched Tanzanite necklace also selling at Sotheby's.
The rare gemstones are currently touring various cities on their way to the Hong Kong auction, and upon their sale, they will become part of a living gallery of seven-figure value gemstones displayed throughout the Kat Florence Hotel in Canada.
