Star Sapphire from Thailand

Star Sapphire from Thailand 6.66 ct


A star sapphire from Thailand is a wonderful guiding star in the night sky! It is a natural gemstone with a rare asterism effect, also known as "star". And the star that appears on the mirror surface of the cabochon is called "asteria". Thanks to the thin needles of the rutile mineral that are "embedded" in corundum, light is reflected in a certain way, and we see it as a star. This example of a star sapphire weighs 6.66 carats. Coloring – black, with bronze reflections. The cabochon is oval. No heat treatment.
