On June 10, 1988, "Guangming Daily" reported that "South Africa Kimberley found one of the world's largest diamonds", weighing 599 carats, valued at 30 million US dollars, compared to another giant diamond "African Star Cullinan No. 1 also weighed 69 carats. I don't know if the Kimberley diamond weight mentioned here refers to the weight of the original stone or the weight after processing. If the weight of the finished product after processing, the original stone of Kimberley diamond is much lighter than "Cullinan"! Because "Cullinan" was originally 3,106 carats.
"Cullinan" was discovered on January 25, 1905 in the "Prime Minister" mine in Prydonia, Transvaal, South Africa. At that time, the chairman of the mining diamond company called Cullinan, the newly discovered giant diamond was named after his name. Transvaal was a British colony at that time. The colonial government bought it for £150,000 and dedicated it to King Edward VII as his birthday gift.
This diamond has three natural crystal faces. Experts think it is a crack with a giant drill that is twice as large. Three years later, on January 29, 1908, the British royal family handed it over to Europe's finest jewellery and craftsman, Joseph of Amsterdam, the Netherlands. Askey processing. He found a crack in "Cullinan" and had to cut it. He repeatedly looked at the months and wondered where to start. Finally, I saw the position and made up my mind. On February 10 of the same year, he invited several famous jewelers to help out. After preparing to stop, he held his breath and pointed the crack on the diamond with a special chisel. After a moment of contemplation, he hammered it down... Due to excessive excitement, he immediately fainted and passed away for a long time before he woke up. After that, he trembled a few times to "surgery" before completing the cutting work. It took a lot of work to process it into two large pieces, seven pieces and ninety-six small diamonds. All are crystal clear and pure.
The largest piece was named "African Star" by Edward VII, also known as "Cullinan No. 1", weighing 530.02 carats, with seventy-four crystal faces, becoming the king of diamonds. Mosaic on the token of the British King. The second "Cullinan II" is smaller than it, but it also weighs 3,714.00, with sixty-six crystal faces, set in the crown of the United Kingdom, and two smaller diamonds. It weighs 94.4 and 63.65 carats. When the Queen of England was enthroned, she was set in her crown. At the "Imperial Diamonds" exhibition held in London in 1959, they participated as brooch accessories. Since "Cullinan One" is called "African Star", the second, third and fourth are also called "African Stars". The 105 diamonds processed by Cullinan weighed a total of 1,063.666 carats, which is only 34.25 percent of the original stone. In other words, 65.75 percent of the original stone was lost during processing.
In the area where "Cullinan" was discovered, two large diamonds weighing 354 and 600 carats were found in 1905, and some diamonds with a total weight of 1,500 carats were found in 1919. In 1954, a giant diamond weighing 4,256. 6 carats was found. The texture is extremely high. The latter was named "The Snow Queen" and was processed into three diamonds of 197, 40 and 30 carats. The largest of them was purchased by the Greek ship king Niacos for $2 million.
