In many cultures of the old and new worlds, the turquoise gemstone (Firoozeh stone) has been esteemed for thousands of years as a holy stone, a bringer of good fortune or a talisman. The oldest evidence for this claim was found in Ancient Egypt, where grave furnishings with turquoise inlay were discovered, dating from approximately 3000 BCE. In the ancient Iranian Empire, the blue gemstones were earlier worn round the neck or wrist as protection against unnatural death. It was known that turquoise crystals have healing properties. It is claimed that turquoise stone has the power to prevent panic attacks.
