It measures over 6 centimeters wide and weighs 813-carats.

Switzerland-based de Grisogono has acquired the rights to market The Constellation, which earlier this year set a record for the world’s most expensive rough diamond, Mining.com reports. The purchase was announced at a Sept. 9 press conference at the opening of the 28th Biennale des Antiquaires in Paris. Financial terms of the deal were not disclosed. The diamond, which measures over 6 centimeters wide, weighs 813-carats and was discovered by Canada-based Lucara Diamond at its Karowe mine in Botswana in November 2015. In May, Dubai-based Nemesis International paid $63.1 million for the stone in an auction. Fawaz Gruosi, de Grisogono founder and executive board member, says: “To be able to bring my creative skills to the cutting and setting process of such a stone is both an honour and a privilege and I cannot wait to realise my vision for it.” De Grisogono explains that its partnership with Nemesis International allows it “to access the most precious rough diamonds, manage the entire cutting process and bring the very highest quality stones to its clients, combined with the distinctive de GRISOGONO creativity and craftsmanship.”

Ready to Relocate? Wilkerson Makes Your Move Seamless

When Brockhaus Jewelry decided to leave their longtime West Main Street storefront for a standalone building elsewhere in Norman, Oklahoma, owners John Brockhaus and Brad Shipman faced a familiar challenge: how to efficiently reduce inventory before the big move. Their solution? Partnering with liquidation specialists Wilkerson for a second time. "We'd already experienced Wilkerson's professionalism during a previous sale," Shipman recalls. "But their approach to our relocation event truly impressed us. They strategically prioritized our existing pieces while tactfully introducing complementary merchandise as inventory levels decreased." The carefully orchestrated sale didn't just meet targets—it shattered them. Asked if they'd endorse Wilkerson to industry colleagues planning similar transitions—whether relocating, retiring, or refreshing their space—both partners were emphatic in their approval. "The entire process was remarkably straightforward," Shipman notes. "Wilkerson delivered a well-structured program, paired us with a knowledgeable advisor, and managed every detail flawlessly from concept to completion."
