The Golden Jubilee Diamond (not the Diamond Jubilee!) is the
largest faceted diamond in the world weighing 545.67ct. This yellow-brown
diamond was cut by Sir Gabi Tolkowsky, whom we mentioned in our previous post
Diamond Cut: The Human Factor. Gabi had been hired by DeBeers to cut the famous
Centenary Diamond (a 273.85 D-Flawless diamond), however, the tools required to
cut a stone this size had never been conceived. Thus, Gabi took what everyone
thought as a big ugly brown diamond rough in order to practice and develop the
necessary tools to cut the Centenary Diamond. After two years working in a
vibration proof bunker, Gabi emerged with the now famous Golden Jubilee Diamond,
along with all the tools he now needed to cut the Centenary Diamond.
The diamond is currently owned by the King of Thailand. It’s
apparently valued at $4-12 million.
