One stone that reigns at the top of blue sapphire!
Unheated royal blue sapphire 3.10 CT from Burma

Burma, Kashmir, Unheated, Royal Blue, Cornflower

Among the many sapphires, the above words are the conditions for high-quality crystals.

It is one stone with the best possible combination.
If you are a senior collector, I think you can understand this meaning.

Even if it's from Burma, it's not necessarily beautiful.

Even unheated, which is highly rare, is not necessarily beautiful.

Even if it is simply called royal blue, I don't know what the real best color is.

It is a top quality sapphire that meets all such conditions.

You may have seen some blue sapphires called royal blue or cornflower.

Currently, it is described as such when it meets the color standard by the identification agency.
Royal blue sapphire, in its original connotation, refers to the highest quality crystals from Burma.
(Corn flour refers to the highest quality from Kashmir)

A single stone with a wide cut face of 3.1 CT size actually feels more than 4 CT when viewed from the front.

Large grains with very few inclusions and a wonderful blue glow.

It is a reliable sapphire specified in the report of GIA (Gemological Institute of America), one of the world's most trusted identification organizations.

We always purchase beautiful unheated sapphires with a focus on high quality, but there are very few opportunities to meet sapphires with such a high degree of perfection.

A top-class unheated royal blue sapphire from Burma that doesn't need much to say.

We confidently recommend it as one of the ultimate collection stones.
