The largest Cullinan I is embedded in the scepter of the king of England, the second is embedded in the crown of the king of England, and the third and fourth are embedded in the crown of Queen Mary.

Cullinan's discovery was very accidental. 1902, Thomas Kalinan, a wealthy construction contractor from Johannesburg, and percival Tracy, a prospector, bought a kimberlite copper mine in Transvaal for 52,000 pounds. Subsequently, they established Primia Drilling Company.

1905 65438+1On October 25th, a manager named Welsh happened to see something shiny on the ground of the mine. He dug it out with a knife and saw that it was a huge gem diamond. Cullinan is not a complete crystal, it is only a part of a big crystal. Cullinan was too big for anyone at that time. Later, it was acquired by the local authorities in Transvaal, South Africa for 6.5438+0.5 million. On February 9th, 654.38+0.907 was presented to the British royal family to celebrate the birthday of King Edward VII.

So, how much is the Cullinan diamond worth? At that time, experts in the gem industry estimated that the value of raw ore was as high as $7.5 billion. Then there was an algorithm. The color and transparency of Cullinan diamonds are very good. According to the market price, if the price of a diamond weighing 250 carats is 500,000 pounds per carat (about 5.05 million yuan), then the combined price of Cullinan brooch No.3 and No.4 should be 78 million pounds (about 787 million yuan).

The king of England handed the project of processing this giant diamond to the famous Dutch company Ascher, which once processed a "noble" diamond. After Cullinan was split up, it was pondered by three skilled craftsmen. It took them more than eight months to work 65,438+04 hours a day. A * * * was ground into 9 large diamonds and 96 small diamonds, which were used as ornaments such as crowns and scepters respectively, leaving a rough stone (weighing 9.5 carats) unprocessed. The total weight of this 105 diamond is 1063.65 carats, accounting for 34.25% of Cullinan's original weight. It can be seen that the weight loss of diamonds after being processed into diamonds is great.

The nine big diamonds grinded by Cullinan all belong to the British royal family. The largest diamond is named "Cullinan 1", also known as "Star of Africa", weighing 530.02 carats. It is well-deserved to be called "the king of diamonds", and the background is the power struggle of the king of England.
