Natural Unheated/Untreated Thai Black Star Sapphire Gemstone with Six Golden Rays

Here is a Stunning Star gemstone! The star is quite sharp and well defined. This stone would be excellent for a ring-center stone. The star is visible in normal light conditions, and is very sharp under a pen light or transmitted beam.

Thai Golden Star Black Sapphires are one of the most fascinating forms of sapphire. These sapphires differ from other colors of star sapphires because the star is formed not due to Rutile silk but due to Hematite plates (to which it also owes its golden colour). Such is the magnificence of the star that one falls in love with it.

Specialty

  • Black Star Sapphires are often found from Thailand (Bang-Kha-Cha and Khao-Ploi-Waen) and West Africa (Guinea, Sierra Leone, Liberia). It often happens that along with the star formed due to hematite plates the gemstone also contains rutile silk.

  • Black star sapphires are usually low domed so as to best display the star as a very high dome would make the arms of the star invisible and only a golden sheen would be observed.

Mining areas

  • Black star sapphires are found from Thailand, Guinea, Sierra Leone, Liberia, Burma, India, Sri Lanka (Ceylon), Tanzania, and a few other localities.

  • Black Star Sapphires from West Africa and India often display a Silver-Black, Purplish-Black or Pinkish-Black color, whereas those from Thailand, Burma, Sri Lanka & Tanzania bear a Golden-Black color.
