Read on to learn about this magical stone!

The ancients regarded star sapphires as powerful talismans for protecting travelers and seekers. They were considered to be so powerful that they would continue to protect the wearer even after being passed on to another person.

In the gemstone world there are a special group of gems known as phenomenal gemstones. These are gems that exhibit special optical phenomena, including Asterism; the star effect.

These phenomenal ges are fairly rare! Star Sapphire (the star effect) is an example of an optical effect found very rarely in a small number of gem types cut as cabochons. The most famous examples are star Sapphire and star Ruby!

The reason that asterism is so rare is that it requires the gem to have inclusions of rutile needles, and for the needles to be aligned in such a way as to reflect light in a multi-rayed pattern forming a star. 

The value of a star sapphire depends on the clarity of the star, the color of the stone and the number of rays in the star. Thailand is famous for the black and gold star sapphires found only in Chanthaburi Province .

Hence this is a very desirable, sought after stone.  Have a close look at the photos of this vintage beauty!
