This ring shines with a 1.01ct oval cut diamond that is completely flawless, completely colorless, and of the highest quality in the world with the ultimate in elegance and brilliance.

The center stone is a rare D color IF clarity EX cut diamond that has received the highest rating in all 4C diamond evaluation criteria, making this ring truly sublime.

The highest quality of diamonds, D Color and IF Clarity, are far more lucrative, portable, and secure assets than cash, 24-karat gold, or real estate.
D color is completely colorless and no minute difference from any other color can be detected.
IF Clarity is also completely flawless, meaning it is extremely pure, with no internal inclusions of any kind, and is as transparent as ice.
You will lose track of time and never get tired of looking at it, even if you look at it for hours.

The same quality and design are 100% guaranteed at the lowest price!
It is an asset more valuable than cash. This is a gem that deserves to be a commemorative diamond or a special gift.

Cash is rapidly declining in value, and it is predicted that in 10 years time, 1 million yen today 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.

There is a big difference depending on what you choose to spend your precious property on.
The world's wealthy are increasingly converting their cash into valuable physical objects.
For asset protection, diamonds are one of the most suitable.
The lowest price guaranteed for the same quality, size, and design.
In certain world-famous brands, the price is always over 10 million yen.

If you are going to buy, you should buy the highest quality at the lowest price.

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.
