As far back as approximately 1700 BC, Turquoise was used in China mainly for ornamental carvings and other artistic purposes. In Beijing, at the Academy of Social Sciences, there is a bronze and turquoise plaque on display which is thought to be from that era. Chinese turquoise is almost always stabilized, and will not be as likely to be affected by lotions or perfumes when it is worn, protecting the color of the turquoise from outside elements.
Sleeping Beauty Turquoise comes from the Sleeping Beauty Mountain in Globe, Arizona, which is one of the largest mines as to date. Sleeping beauty comes in many hues of light to dark blue. Turquoise is mainly found in the US, Australia, Chile, Mexico, and historically, Iran.
Mohs' Hardness score is based on a 10 point scale where 10 is the most resistant, like a diamond, and 1 is easily scratched, such as Talc. Turquoise gets a score of 5-6, meaning that it is fairly scratch resistant and therefore suitable as a component of everyday jewelry. Turquoise gemstones should be regularly cleaned by a professional or with a soft rag and mild soap and water. Other methods, including ultra-sonic clenares, solvents and harsh chemicals should be avoided when cleaning your handcrafted jewelry as exposure to these elements can damage semi-precious and precious gemstones and pearls.
