Golden Jubilee Diamond

gold·​en ju·​bi·​lee di·​a·​mond | ˈgōl-dən jü-bə-(ˌ)lē dī-(ə-)mənd

noun

A 545.67 carat brown diamond, discovered in 1985, and currently the largest cut and faceted diamond in the world

Discovered in South Africa in 1985, the Golden Jubilee Diamond is a 545.67-carat brown diamond, weighing more than 109g. It is the largest of its kind in the world, beating the second-largest diamond, the Cullinan I by more than 15 carats. The discovery of the Golden Jubilee only further increased the fame of the Premier Mine in South Africa, where the Cullinan I, Taylor-Burton, and Centenary diamonds were all found throughout the 20th century. It took two years of work to cut the Golden Jubilee, so relatively few knew of its existence before 1990. Today, the diamond is owned by the King of Thailand and is on display in Bangkok.
