"You guys learn a little more about Aoi's quietness.?rane?n? ??? ．?ｒ?ａ?ｎ?? ena'com" Zhu Zi smiled.

Aoi Miyazaki shrugged his shoulders: "Zhu Zijun, while you can still relax in the past few days, let's relax as soon as possible." When you get married, you'll know how precious this ease is now. ”

"Zhu Zijun, where are you going to spend your honeymoon after marrying Sesame Sauce?" asked Sho Sakurai.

"It's here, what a beautiful view. It also saves a long journey, and by the next time we meet, I estimate that mahjong has already given birth to twins. Zhu Zi said with a smile.

"Zhu Zijun, you are really confident in Sesame Sauce. Oguri said with a smile.

"I'm not confident in Sesame Sauce, I'm confident in myself. Zhu Zi said triumphantly.

Masami Nagasawa's pretty face turned red all of a sudden.

"Zhu Zijun, there are a lot of AKB and Nogizaka members here. Are you really good at talking about meat jokes like this?" Aragaki Yui said helplessly.

Zhu Zi glanced at the members and found that Ikuta Erika was squeezing her eyebrows at her.

"It's okay, they're thick-skinned. ”

The crowd was speechless.

"Sesame sauce, this diamond ring on your hand is so beautiful. Mao Inoue's sharp eyes noticed the diamond ring on Masami Nagasawa's hand.

"This is the Star of Africa. Zhu Zi said lightly.

"Star of Africa?" everyone looked at Zhu Zi at the same time.

Zhu Zi nodded lightly.

The so-called Star of Africa refers to the world's largest rough diamond, which was discovered in 1905 at the Premier mine in South Africa and weighed 3,106 carats. Because the rough stone is too large, it needs to be broken down into several pieces. Later, it was cut and polished into many diamonds of various sizes. The largest is mounted on the Emperor's scepter and weighs 530.2 carats, known as the "Star of Africa".

The Star of Africa diamond is a natural diamond processed from Cullinan. "Cullinan" was discovered on January 21, 1905 at the Premir Mine in South Africa. It is pure and transparent with a pale blue hue and is the best grade gemstone diamond with a weight of 3,106 carats. Until now, it is the largest gemstone found in the world.

The Star of Africa is the largest cut diamond in the world, weighing 3,106 carats. The diamond was cut by an American company that studied it for 6 months before deciding how to cut it.

In January 1905, Fredville, the supervisor of the Premir diamond mine in South Africa, was walking in the mine when he found a shining object in the reflection of the setting sun. As a result of his acquisition of the Treasure Treasure Vaultlinan, he received a bounty of $10,000.

After Cullinan was split, it was milled for 8 months by three skilled craftsmen, who worked 14 hours a day. A total of 9 large diamonds and 96 small diamonds were polished. The total carat weight of these 105 diamonds is 34.25% of the original weight of Cullinan. The largest of them is called "Star of Africa No. 1", which is drop-shaped and weighs 530.2 carats. It has 74 facets and is set on the scepter of the King of England and is now in the collection of Buckingham Palace in the United Kingdom. The next largest one, called the "2nd African Star", is square, 64 faces, weighing 317.40 carats, and is set in the crown of the British Empire.

When a 3,106-carat diamond was discovered in South Africa in 1905, news of the new transatlantic cable spread around the world, with gem experts estimating the value of the ore at $7.5 billion. Since South Africa was a British colony at the time, it was agreed that it should be shipped to London and presented to King Edward VII. This one-of-a-kind treasure has sparked the minds of jewel thieves around the world, and it took months to think about how to secure the transport. In the end, the Metropolitan Police decided that the best principle was "the simpler, the safer". The eggplant-sized diamond was mailed in an unmarked package and showed up at the Royal Post Office at Buckingham Palace a month later. On February 10, 1908, the diamond was split into several large pieces and processed. The total amount of finished diamonds processed is carats, all of which are owned by the British Crown. The largest diamond, named Cullinan 1, also known as the "Star of Africa", weighs 530.02 carats.

Speaking of the king of diamonds, the "Star of Africa" deservedly, the second largest gem-quality diamond in the world at that time was discovered in January 1905 in the Premir diamond mine in South Africa, called the "Cullinan" diamond, is a crystal is not very complete diamond block, the color is colorless and transparent, without any flaws, excellent texture, weighing 3106 carats. The name "Cullinan" was taken from the name of the general manager of the mine at the time.

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

The "Cullinan II" is square, weighing 317.4 carats, and is set in 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.

The Cullinan diamond is cut into nine large diamonds and 96 small diamonds, which are used for crowns, scepters 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 3,106-carat "Star of Africa" rough was cut into 105 diamonds and 9.5 carats of uncut gravel. The weight of the finished product is only one-third of the rough stone, which shows that the cost of polishing the rough into a diamond is very large.

Fourteen years later, in 1919, still in the same mine, not far from finding the "Star of Africa" diamond, and found an incomplete diamond block weighing 1,500 carats, which should rank second in the world according to weight, it must be named separately, but people studied the characteristics of this piece of diamond, and according to its crystal characteristics, fissure shape and other characteristics, it was determined that it belonged to the same crystal as the "Star of Africa" found in 1905, but the "Star of Africa" was found first after the fissure, so it was not named again. In other words, if the "Cullinan" of the "Star of Africa" had not been cracked, its total weight would have been more than 4,606 carats.

"The diamond of this heart star is the African Star Five, and when the Queen of England heard that I was married, she specially gave this diamond to me as a wedding gift. Zhu Zi said lightly.
