These are the largest, top clarity, and highest quality diamonds available in Japan today.

Even the world's top brands such as Harry Winston, Graff, Cartier, etc., do not carry them in Japan.
If you were to order one, it would easily cost 400~500 million yen.

VIPs around the world are looking for diamonds of the highest quality.
The value of these diamonds continues to rise, they are easy to carry, and they can be exchanged for cash anywhere in the world.

If you are serious, you can make an appointment to see the diamonds in person before you purchase them.

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.
Tokyo, Female (40s)
