Turquoise derived its name from French words ‘Pierre Turquoise’, which means ‘Turkish Stone.” This was because, the trade route through which the stone came to Europe from Asia was through Venice and Turkey.
For ages, Turquoise has been a part of various cultures and symbolized as the stone of nobility, wisdom, immortality, luck, protection, and power. Being the stone of strength, it is believed to be good for depression, panic attacks, or exhaustion. Turquoise is also said to boost the physical as well as mental immune system.
