Discovered in South Africa, this rough 650.80 carat stone yielded a beautiful diamond of exceptional clarity and purity. Named the Jubilee in honour of the diamond jubilee of Queen Victoria's coronation, it is the fourth-largest, colourless, faceted diamond in the world.

It was purchased by Sir Dorabji Jamsetji Tata and was disposed off by his heirs after his death in 1932. Cartier's, who were to auction the diamond, put its sale tag at pound 75,000.

It was purchased by well-known French industrialist Monsieur Paul Louis Weiller, who allowed it to be displayed in several exhibitions around the world.

It is presently owned by Robert Mouawad, head of the international jewellery empire, Mouawad Jewellers, and a well-known collector of diamonds. It is the largest diamond in his collection and is known as the Mouawad Jubilee.
