In recent years, the value of cash has been declining rapidly, and it is predicted that in 10 years time, the current one million yen will no longer be worth 500,000 yen, or even 300,000 yen.
In comparison, the highest quality diamonds are expected to be worth so much more in 10 years' time that a one million yen diamond will be worth 1.5 million yen, or even 2 million yen.

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)
