Hello everyone ^^

It is a mountainous area of ​​Aye Isuzu east.

Today, I would like to talk a little bit about the legend of the diamond cutters brand "ROYAL ASSCHER", which emits a white and noble brilliance.



Founded in 1854 in Amsterdam, the Netherlands.
We have established a solid position as a prestigious diamond jeweler.



One of the most famous stories is that the brand was entrusted with cutting the world's largest rough diamond, Cullinan .





Cullinan's rough stone / quoted from wikipedia

A rough diamond found in the Cullinan Mine in South Africa on January 26, 1905, it weighs 3106.75 carats (621.35g), the largest in the world !

Said to be roughly the size of an adult's fist, Cullinan is believed to be part of a larger rough stone, the rest of which has yet to be discovered.

How much does a diamond in the rough, which is said to be so precious and priceless, cost ? ! I tried to find out ^^



The answer is... over $2.4 billion! It is worth about 260 billion yen in Japanese yen. There was!



After mining, Cullinan was sold to the Transvaal government in South Africa and presented to King Edward VII of England as a gift on his 66th birthday on November 9, 1907.

After that, it was stored carefully, but diamonds do not shine as they are in the rough. "It's a diamond that shines." We asked Usher to cut it, and three polishing craftsmen led by Usher did the cutting.

It is said that he spent months analyzing the diamonds before they were cut.

*Diamond boasts a Mohs hardness of 10 (strength against friction and scratches), which is the highest class among "natural substances", but it is said that its toughness is almost the same as quartz, and it can be impacted from a certain direction. has a weak property against





Finally, in 1908, the first division was done, but the tool used to split it broke first.

Even so, this division work was done every day without giving up, but a series of failures.

The craftsmen were tense and stressed, and after a few months they were finally able to break it into the best shape, but Usher, who was in charge, passed out from too much fatigue and tension. so much is left.



9 large diamonds and 96 small diamonds were cut out. The nine stones, each named Cullinan I through IX, are all owned by the British royal family or members of the royal family, and some are on permanent display at the Tower of London.

I thought that it must be heavy with such decorations ^^





When I hear stories like this, I can say that the rarity of diamonds, the difficulty of cutting them, and the everlasting brilliance that comes from them are truly the result of an accumulation of miracles.

I am also a regular user of Royal Usher wedding rings, but whenever I look at them, I am fascinated by Usher diamonds that sparkle elegantly and beautifully in my hand.
