Chongzhen Emperor Zhu Youzhen in the process of giving Wang Chengen, he is also fully turning his thinking, he originally wanted to mine by himself, once if he brought five hundred catties of diamonds over, he also listened to the ox fork, but he found that he was wrong, first of all, he found that the reason why diamonds are valuable is because of the trouble of mining, and the polishing is even more troublesome, to get five hundred catties of diamonds, how long do you have to wait? And mined from China, the information on Chinese diamonds is not very good!

So, Chongzhen Emperor Zhu Youzhen dispelled this idea.

The world's largest gemstone, the diamond, is called "Cullinan", and its discovery was quite accidental. On January 25, 1905, in the Premir mine in South Africa (Azania), there was a manager named Wales, who occasionally saw a glittering object in the middle of the mine's ground, and he dug it out with a knife to see that it was a huge gem diamond. It is equivalent to the fist of an adult man. It is pure and transparent, with a pale blue hue, and is the best grade of gemstone diamond. Until now, it is the largest gemstone found in the world.

The first drill, Cullinan, was produced in 1905 at the Premiar mine in South Africa. 3106.75ct in weight, light blue, fist-sized. It was acquired for £150,000 at the time. In 1907, it was dedicated to King Edward VII of England and processed into 9 large diamonds. Cullinan I., II., III.、...... The IX number weighed 530.20, 317.40 and 94.40 respectively、...... 4.34ct。 The largest number I is set on the sceptre of the King of England, the number II is now set in the crown of the King of England, and the number III is set on the crown of Queen Mary.

Early 1908. Cullinan was sent to Amsterdam, the Netherlands, the most authoritative city for diamond polishing at the time. Give it to the covenant. Aschar processing. The processing fee is 80,000 pounds. Because the rough stone is too large, it needs to be broken into several small pieces according to the plan in advance. Breaking it is an extremely difficult task, because if not enough research or technology is good, this huge gem can be shattered into a pile of small pieces of little value.

The crushing work was carried out by famous Dutch craftsmen about. Aschar conducted. He spent several weeks studying Cullinan, building a glass model of its size and shape, and designing a set of tools. He first used these tools to test the glass model, and the result was that the model was split according to the expected requirements. After a few days of rest, February 10, 1908. He and his assistant went to a special workshop, clamped Cullinan tightly in a large pliers, and then placed a special steel wedge in a pre-ground groove on it. About. Aschar struck the steel wedge with a heavy stick, and with a "snap", Cullinan did not move, but the steel wedge broke. A cold sweat dripped, and in the tense atmosphere that looked like it was about to explode, Aschar put a second steel wedge. Tapping harder a little more, this time, Cullinan split in half exactly as planned. Aschar, on the other hand, passed out on the floor.

After Cullinan was split by three skilled craftsmen. I worked 14 hours a day and pondered for 8 months. A total of 9 large diamonds and 96 small diamonds were polished. The total weight of the 105 diamonds is 1063.65 carats, which is 34.25% of the original weight of the Cullinan. It can be seen that after diamonds are processed into diamonds, there is a significant loss of weight.

The "Cullinan First" is a pear-shaped, the heaviest of the three, weighing 530.2 carats, and was later set in the scepter of the British king, and this giant diamond is called the "Star of Africa". It has 74 facets.

The "Cullinan II" is a square, 317.4-carat square set with a backset in the center below the crown of the King of England.

The "Cullinan III" is pear-shaped, weighing 94.4 carats, and is set on the spire of the Queen's crown.

The "Cullinan IV" is a square shape weighing 63.6 carats, and it was made by dividers who divided the smallest of the diamonds into two, namely the "Cullinan III" and the "Cullinan IV". It is set on the side of the Queen's Crown.

Cullinan was cut into nine large diamonds and 96 small diamonds for the crown, scepter, and other decorations. The remaining five of the nine diamonds are: the fifth heart-shaped 18.8 carats, the sixth 11.5-carat, the seventh 8.8-carat, the eighth rectangular 6.8-carat, and the ninth pear-shaped 4.39-carat. In addition, there are 96 small diamonds, which have been scattered around the world and weigh a total of 8 carats. The remaining pile of very small and unfathomable gravel weighs 9.5 carats.

The 9 diamonds milled by Cullinan are all owned by the British Crown. Among them, "Cullinan I" and "Cullinan IV" were set in the crown of Queen Mary, made in 1911, and later removed from the queen's collection, and the crown was replaced with a replica of crystal. In 1919, another gemstone weighing 1,500 carats was found in the Premir mines. It is the third in the world by weight. It is also a fragment of a large crystal, and is similar in color to Cullinan. Therefore, it is believed that it was broken into the same large crystal as Cullinan, so the diamond was not given a special name.

"Damn!" Chongzhen Emperor Zhu Youzhen shouted!

Wang Chengen was taken aback, he accompanied the emperor for a long time to see about diamonds, this kind of thing that even a great eunuch like him who has seen countless treasures has never seen, he doesn't know what the emperor wants this for, Wang Chengen is a person who knows the goods, he feels that diamonds are such a thing, make Da Ming, guarantee that no one likes it, there is no use at all! I suddenly heard the emperor swearing, the emperor only scolded when he was angry, I don't know if the emperor is good, why is he suddenly angry again?

Wang Chengen hurriedly knelt down and kowtowed, "The emperor is angry, the emperor is angry, the old slave should die, the old slave should die." ”

Emperor Chongzhen Zhu Youzhen laughed, and hurriedly pulled Wang Chengen up, "Big companion, don't be afraid, I'm happy!" It turned out that the diamond on the British crown was called Cullinan, January 25, 1905, at the Premir Mine in South Africa (Azania). It was mined and split in half, so it shouldn't have been mined yet, and it's still a complete one! ”

Wang Chengen didn't understand it at all, he didn't understand the concept of time in the emperor's computer, so he couldn't understand what the emperor said.

Emperor Chongzhen Zhu Youzhen himself didn't quite know what he was thinking about now, he only felt that the question seemed to have become simpler! (To be continued......)
