Product Description

The mere existence of a natural diamond of this size is an amazing thing, but when it comes to an intact, internally flawless IF class diamond, there are very few such diamonds in the world.
Of course, there are no other diamonds in Japan.
It is a treasure of the highest order.
We have acquired, cut, and created these diamonds from huge gemstones of the highest quality.

They are virgin diamonds, not pawnshop or second-hand diamonds.
You will be the first owner to own one.
This is an asset that will last for generations, more lucrative than cash.

Only serious buyers can make an appointment to see the actual property for purchase.

The actual diamond is much brighter and more beautiful than the photos and videos.

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.
