A stone that makes you feel the mystery of nature
Black Star Sapphire 6.91 CT

RECOMMEND POINT
Enjoy the impressive large grains.

Black star sapphire gives you a sense of the mystery of nature!
When exposed to strong light from one direction, a star suddenly appears.

You can even see the stars using a common item like the light from your smartphone.

The asterism of this mysterious black sapphire is not caused by silk inclusions, but by the light effects of a lamellar structure due to the inclusion of hematite (iron oxide).

When a spotlight is shone on it, the six-pointed star appears, and everyone is amazed by the night sky-like body color and the appearance of the star.

A beautiful and bold star, like a star floating in the night sky. Enjoy this beautiful twinkling.

*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.
