What is the world's largest diamond?

Answer 1

The largest rough diamond was the Cullinan diamond. It weighed 3,160 carats, and was about the size of a bowling ball, I think.

Answer 2

G'day U En A,

Thank you for your question.

The Cullinan Diamond, part of the British crown jewels, was the largest gem-quality rough diamond ever found (1905), at 3,106.75 carats. One of the diamonds cut from it, Cullinan I or the Great Star of Africa, was formerly the largest gem-quality cut diamond at 530.2 carats, but now that title has been taken by the Golden Jubilee (1985), a 545.67 carat, yellow-brown diamond. The largest flawless and colorless (grade D) diamond is the Centenary Diamond which weighs 273.85 carats. The Millennium Star is the second largest (1990) at 203.04 carats.

Regards

The Cullinan Diamond

This 3,106 carat diamond is the largest gem diamond ever found. It was discovered in 1905 at the Premier mines in South Africa by Frederick Wells, a mine superintendent. He was walking through the mine at the end of the day, when he happened to glance up. He noticed a large mass in one side of the mine wall. Thinking it was a big piece of glass embedded by a practical joker he examined what turned out to be a huge diamond. Wells received $10,000 for his find. The diamond was named Cullinan, after the mine's owner Sir Thomas Cullinan.
