In the previous articles, I have introduced many varieties of jewelry to you. Today I will introduce you to the world's largest rough diamond - The Cullinan. I hope that through the introduction of this diamond, I can bring you more interesting diamond knowledge, let's get started.

The " The Cullinan  " is the largest cut diamond in the world at 3106 carats. The diamond was cut by a company in the United States, which took six months of research to determine how to cut it most efficiently.

In 1905, South Africa discovered a diamond ore weighing 3,106 carats. The newly opened transatlantic cable spread the news quickly around the world. At that time, gem industry experts estimated that the value of the original ore was as high as 7.5 billion US dollars. Since South Africa was a British colony at the time, it was agreed that it should be shipped to London and dedicated to King Edward VII. Jewelry thieves from all over the world have been thinking about the unparalleled treasure, and officials have spent months figuring out how to secure it in transit. In the end, the Metropolitan Police decided that the best principle was "the simpler the safer". The diamond, the size of an eggplant, was mailed in an unmarked package and showed up at the Royal Post at Buckingham Palace a month later. On February 10, 1908, the giant diamond was cleaved into several large pieces for processing. The total amount of polished diamonds processed is 1,063.65 carats, all of which belong to the British royal family. The largest diamond is named "Cullinan No. 1", also known as the "Star of Africa (Cullian)", weighing 530.02 carats.
