Jewelry made from the world’s largest diamond is to go on display June 30 at Buckingham Palace as part of the Queen’s Diamond Jubilee. The Cullinan Diamond, which weighed 3,106 carats in its rough state, was discovered at the Premier Mine near Pretoria, in South Africa in 1905.
The diamond was cut by I.J. Asscher and Company of Amsterdam. Nine principal stones, 96 smaller stones, and nine carats of unpolished fragments were produced. The two largest gems form part of the Crown Jewels—one is set at the head of the Sovereign’s Scepter and the other into the Imperial State Crown.
The other seven were mounted in various settings for Queen Mary, wife of George V.
