A mysterious crystal with a strong presence, Black Star Sapphire 6.21CT

RECOMMEND POINT
This is a black star sapphire from Chanthaburi, Thailand, where a mysterious six-star star appears on the lustrous crystal.

Black star sapphire from the Chanthaburi area of ​​Thailand is attractive for its jet-black lustrous crystals.

The asterism of black sapphire is not due to silk inclusions found in rubies and sapphires from Myanmar or Sri Lanka, but is due to the light effect due to the lamellar structure due to the inclusion of hematite (iron oxide).

In addition, mining in Chanthaburi is currently severely restricted, and the amount mined is quite small, and it is said that what is being traded on the market is the existing stock.

A dark and opaque glossy black star sapphire that exhibits a mysterious asterism effect due to the lamellar structure of iron oxide!

An attractive loose piece with a mysterious star spread sharply on crystals with a wonderful luster.

Enjoy the special effects created by nature with a penlight in hand.
