The most exquisite treasure] 9.47ct Unheated Sapphire from Sri Lanka
2.87ct Diamond Pt900 Necklace with GIA Certificate of Authenticity

Miraculous deep blue, nurtured by the earth over hundreds of millions of years.
This unheated Sri Lankan sapphire is a miracle, one of only a few thousand pieces.

Unheated sapphires, which are said to be one of only a few thousand pieces, are miraculously clear and brilliant in their natural beauty without any artificial heat treatment.
The moment you see it in front of your eyes, it gives off a special aura that draws you into its deep, clear blue world.

▼ Top quality proven by GIA

The GIA (Gemological Institute of America), the most authoritative organization in the world, has certified "Sri Lanka" and "No Indications of Heating" as genuine top quality.
The overwhelming presence of the nearly 10-carat (9.47ct) piece will charm anyone who sees it at first glance and bring out the elegance of the person wearing it to the highest level. The pure brilliance created by nature by chance has a strong shine that seems to overflow from within.

▼ An "asset" to be handed down to the next generation

The main stone is surrounded by 2.87cts of high-grade diamonds and the finest platinum to support the supreme brilliance.
The luxurious line of diamonds that beautifully adorns the décolleté emits a refined radiance with every movement, creating a gorgeous effect around the face. It is a masterpiece that transcends the framework of mere jewelry and is valuable as an asset to be handed down to the next generation.

Check the real thing.

For those with a high sense of beauty who want to obtain a piece of genuine value that no one else will have.
You can confirm the overwhelming beauty that cannot be conveyed in a photograph directly at our office. Please make an appointment and feel free to visit our office.

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.
