The impact of a large black star!

There are a whopping 29 CT!

When exposed to strong light from one direction
Stars emerge from large crystals!

This phenomenon is called asterism.

The mysterious black sapphire asterism
It is not due to silk inclusions,
Due to the inclusion of hematite (iron oxide)
This is due to the effect of light on the lamellar structure.

The glow of the rising six-pointed star is very mysterious.

Stars that stand out without blending into the background color
It's a very impressive word.

It contains some inclusions,
First of all, there are of course inclusions.
For a star to appear, the relationship with the inclusions is
It will become an inseparable thing.

The beautiful presence of this star sapphire

*Star stones are evaluated after only the surface is polished.
The sides and back are not polished, leaving them in a natural, uneven state.
Thank you for your understanding in advance .
