Turquoise is one of the oldest gemstones known to man, discovered in ancient Egyptian tombs dating back as far as 3000 BC. It has been considered a good luck talisman by many civilizations including the Persians, the Aztecs and indigenous American Indian tribes.
Native Americans believed that wearing turquoise jewelry provided a direct connection to the heavens above and sources of abundant water supply below; whereas the Aztecs believed the stone was holy, and often adorned their ceremonial masks with turquoise gemstones.
Turquoise provides the bearer/wearer with strong, mutually fruitful relationships and lends self-confidence to individuals who may usually be withdrawn. Turquoise is a gemstone that has always been associated with good luck. For this reason it was cherished by travelers wishing to ward off bad luck.
Though the most valued of turquoise has a sky blue color, it can also be found in various shades of green to yellowish grey. The blue color is created from traces of copper, while the green shades are created from traces of iron or chromium.
Turquoise is rated at a 5 to 6 on the Mohs scale of hardness and because it is a reasonably soft gemstone, care should be taken with it to avoid scratching.
