The largest diamond ever found was given to a king as a birthday present
On 9 November 1907, the Cullinan Diamond was presented to King Edward VII on his birthday. It is the largest gem-quality rough diamond ever found: 3,106 carats, or 621 grams, discovered on 26 January 1905 at the Premier mine in Cullinan, South Africa, and named for the mine's owner, Thomas Cullinan. When it failed to sell in London for two years, the government of the Transvaal Colony bought it, and Prime Minister Louis Botha gave it to Edward. The king had it cut by Joseph Asscher & Co. into several large stones and many smaller ones. The largest gems were set in British royal regalia, and are still part of the Crown Jewels.
The gift was meant as a gesture of goodwill after the Boer War. The diamond's cutting is a famous tale of craft, since a single blow in the wrong place could have shattered it.
Cullinan I, cut from the diamond, is set in the Sovereign's Sceptre with Cross, and Cullinan II is in the Imperial State Crown.
