The price of natural diamonds has skyrocketed, and the higher the quality, the rarer and larger the natural diamond, the higher the price, which is 1.5 to 2 times higher than a year ago.

Natural diamonds of this level at 10 ct. are now almost impossible to find in Japan.
Even among dealers, the price is over 10 million yen.
Even famous brands no longer carry them.

This one is 9.953ct, which is slightly less than 10ct.
Of course, it looks exactly the same as the 10ct piece, but since it is only a fraction of the 10ct piece, we are selling it at the lowest price we can as an inventory clearance.

It will be a family heirloom for generations to come.
If you want to make it into a ring, it will be a powerful natural diamond ring.

Customer Testimonials

I have been interested in physical investments for some time and was considering investing in diamonds.
I first looked for information online, but found it difficult to find a reliable supplier, so I was introduced to Amazing Studio directly by a friend.
We later set up a business meeting and purchased loose diamonds.
The price has already skyrocketed, and we expect the price to go up in the future.
Kyoto, Japan Male (50s)
I was looking for a Paraiba tourmaline ring and came across this site.
(I have searched many websites (and I have found the right one!).
I wanted to check the product first, so I contacted the company and they were willing to help me and I was able to see the actual product.
I am very satisfied with the product, which is better than the price.
