A star that stands out in glossy crystals!
Black Star Sapphire 7.26CT



RECOMMEND POINT
This is a black star sapphire with a beautiful luster and dark crystal shine, and a sharp star that stands out clearly.

The beautiful presence of glossy cabochon crystals.
An attractive black star sapphire with a sharp star that stands out elegantly.

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

When you shine a spotlight on it, the Rokujo star emerges and the plump, richly proportioned crystal takes on a completely different look.

This clearly visible star spreads out like a shooting star depending on how the light hits it, and when you look at it, you can't help but feel immersed in a mystical atmosphere.

A beautiful yet bold star that looks like a star floating in the night sky.Please enjoy this beautiful twinkle in your hand.

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