The ultimate natural sapphire to be treasured for a lifetime!

The deep, clear blue color of the sapphire is so beautiful that you will be...
The brilliance at your fingertips is truly a miracle created by nature.
A rare large unheated natural sapphire weighing 10.14 carats is truly breathtaking.
It is a very special ring that is rare to find.

This ring is made in Sri Lanka, which is famous for producing some of the most beautiful sapphires in the world.
This gemstone, nurtured over many years, has a deep, vivid blue color that can only be found there.
The fact that it is unheated is proof that its beauty is unaltered by human intervention, and that it shines in its natural state.
The powerful and mysterious sparkle that seems to come from within is truly the art of nature.

The sapphire, which has an overwhelming presence of 10.14 carats, has been polished into a graceful octagonal step cut by skilled craftsmen.
The dazzling brilliance created by the well-calculated cut changes its expression depending on the angle of view, allowing the wearer to appreciate its beauty without ever getting tired of it.

It is surrounded by a total of 3.72 carats of sparkling diamonds.
The pure, unadulterated brilliance of only the finest diamonds, carefully selected, enhances the beauty of the sapphire and makes it look like stars shining in the night sky.

The moment you put on this ring, you will be filled with an exuberance and confidence you have never felt before.
Worn for special occasions or for everyday use, it will add a luxurious touch of color to your daily life.

The only one of its kind in the world, your own special jewel.
Please hold this supreme sapphire in your hands as a treasure that will last a lifetime and be handed down from generation to generation.

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)
