An unusual 10-carat blue elegant ruby can bring up to $20 million when it mosts likely to public auction in Geneva on May 13, public auction home Sotheby’s stated on Thursday.
The cushion-shaped item, called the “Mediterranean Blue Ruby,” was extracted in South Africa and categorized as a “elegant vibrant blue,” the highest possible quality for coloured rubies.
” The marketplace for coloured rubies remains to go from stamina to stamina,” Jessica Wyndham, Sotheby’s head of high jewelry sales in Geneva stated in a declaration.
The Mediterranean Blue was reduced from a 31.94-carat harsh ruby found in 2023 at the Cullinan mine in South Africa. Its improvement right into a refined treasure complied with a year of research and 6 months of preparation and cutting, Sotheby’s stated.
Diamonds of this quality are remarkably uncommon. Fancy vibrant blue rubies over 10 carat weights have actually continually regulated high costs at public auction.
In 2016, a 14.62-carat treasure known as the “Oppenheimer Blue” cost 56.8 million Swiss francs ($ 68.7 million) at Christie’s in Geneva, establishing a globe document or an expensive vibrant blue ruby cost a public auction.
That exact same year, a 24.18-carat extreme blue ruby discovered at Petra Ruby’s (LON: PDL) Cullinan mine in South Africa in 2014, marketed for $25 million at a Christie’s public auction in Geneva.
