The Cullinans Diamonds


Cullinan II - The Imperial State Crown With The Cross Showing Cullinan II Set In The Front

The Cullinans, the purest and the greatest of all diamonds, was found in the Premier Mines in South Africa on the 26th of January 1905.  The blue-white magnificent diamond was described in the rough as being a transparent crystal, the size of half-a-brick with a weight of 3106.75 carats.  It was named after the company’s chairman, Mr. Thomas Cullinan.    On the 9th of November 1907, the Prime Minister of South Africa, General Botha, presented the Cullinans as a gift to His Majesty King Edward VII on his 66th birthday.

The diamond was cleaved on the 6th February 1908 by Joseph Asscher, the famous cleaver of Amsterdam.  It was cut into 9 major diamonds and 96 minor diamonds of one, two and three carats.  The two largest stones referred to as Cullinans I and II were named as the First and Second Great Stars of Africa and formed part of the Crown jewels.  The other 7 Cullinans belong to Her Majesty Queen Elizabeth II.
