At the time this diamond was discovered in South Africa, the Cullinan was the largest diamond ever found. It weighs 530.20 carats and has 76 facets. It was cut into more than 100 smaller pieces, the nine largest are in the British Royal Family’s Crown Jewels. The Star of Africa holds the place of 2nd largest cut diamond in the world and is on display with the other Crown Jewels in the Tower of London. Very interesting history on the Cullinan diamond.
