Once part of the most extensive collection of royal jewels to ever exist, this phenomenal 3.79 ruby hails from the crown believed to be part of the French Crown Jewels and owned by the Sultan of Brunei. Excavated from a mine that has been extinct for 150 years, the ruby features perfect “pigeon blood” coloring, stunning clarity and size. Perhaps the finest ruby available, it is set in platinum amongst 2.50 carats of brilliant round diamonds and has been certified by the American Gem Trade Association.
