A truly miraculous gemstone that can only be found in a limited number of places in the world.
This ring is a 39.71ct unheated color change sapphire ring with an overwhelming presence, created by the land of Sri Lanka.

This is truly an exceptional gem with asset value, with an additional special identification letter issued by GIA, which is only issued for rare and valuable gemstones worldwide.

Unlike cash, which is dwindling in value, this is a rare earthly treasure that is becoming more and more valuable.

Jewelry lovers the world over are searching for the rarest of large color-changing sapphires.
Among them, unheated sapphires, which have not undergone any heat treatment, are truly miraculous, and can be said to be crystals of the mysteries woven by nature.
The pure, unadulterated beauty of nature's creation, nurtured over many years in the depths of the earth, gives off a special brilliance that cannot be seen in heat-treated sapphires.

Born under the blue skies of Sri Lanka, these sapphires, which have passed through the ages, glow a sublime deep violet blue in the sunlight during the daytime.
At night, by candlelight, it dramatically changes its color to a passionate purple-red, as if cloaked in a mysterious veil.
The mysterious color changes woven by a single gemstone are so out of this world that it is almost as if time has stood still.

The moment you put it on your finger, you can feel its weight.
It makes you feel the immeasurable power that the earth has nurtured over the long years.
This ring is not just an ornament, but a companion for life, bringing out the best of the wearer's charm and giving him or her confidence and brilliance.

Surrounding it is the brilliance of 2.12 ct. of delicately set, carefully selected diamonds.
The refined platinum design maximizes the beauty of the sapphire, giving it an elegant and glamorous look.

Experience for yourself with your own eyes and skin the one-of-a-kind, never-to-be-seen-again miracle gemstone.

We invite you to see for yourself the inexpressible charm that this ring exudes.

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.
