The world's highest quality natural red diamond.

This size is the largest and only one of its kind in Japan!
And the most expensive and valuable colored diamond in the world today is this natural red diamond!
The rarity of this diamond is that a 0.1ct diamond costs over 10 million yen.
In the past year or two, the price has increased several times, and now it is going up even more.
This is a more lucrative asset than cash.
The value of the Japanese yen continues to decline, which is dangerous. In 10 years, the current 100 million yen is expected to be worth less than 30 million yen.
But in 10 years, a physical, world-class rare red diamond will not be able to be bought even twice as much.
This difference is so great that a valuable rare diamond is a very attractive asset to protect.

And in terms of appearance, this one, 0.75 ct, looks larger than the 1 ct.
A 1ct fancy red SI diamond of the same quality now costs 700 million yen, so this 0.75ct is a very good deal.

Our jewelry craftsmen can also make this diamond into a jewelry design of your choice.
