Hello, this is MITUBACI staff Nishimura.
There was some news today that caught my personal attention very much.
A rough diamond weighing 2,492 carats was found in Botswana!
I can't imagine what 2492 carats is. I saw a picture of the President of Botswana looking at it on the news, and it was a chunk the size of the palm of his hand.
It looks like ice.
A diamond carat is a unit of weight, and one carat weighs 0.2 grams. Therefore, 2492 carats is about 500 grams. That's about the weight of a plastic bottle of diamonds, by far.
The largest size in the MITUBACI diamond ring is 0.7 carat, and it still feels quite large.
The mine is called the Karowe Diamond Mine in Botswana.
There are no flights from Japan to Botswana, so you will have to go via South Africa. The name of the mine, Karowe, means "precious stone" in the local language. It seems that there are many more diamonds hidden in the name.
The method used for mining this time uses the latest X-ray technology. This method allows us to search for rough stones without worrying about scratching them. The value of diamonds varies greatly depending on the presence or absence of flaws, so we would like to mine diamonds in as pristine a condition as possible.
Once dug out of the ground, diamonds are cut and transformed from ore into gemstones.
The *Cullinan Diamond (3,106 carats), said to be the largest rough diamond in the world, was cut into nine large pieces and many smaller (or not) diamonds (a matter of comparison).
*The larger the rough diamond is, the more it is named.
We are looking forward to seeing what kind of beautiful gems and jewelry will be made from the diamonds we found this time!
