IGS (International Gem Society) As early as 4,000 – 5,000 BCE humans, first in the Sinai region of Egypt, and a millennium later in Mesoamerica and China, were mining and working turquoise into jewelry and ceremonial objects. It was so highly valued in Eqypt, that when high quality deposits were exhausted, artisans developed a copper glazed ceramic simulant called faience, rather than abandon use of that sky blue color in their artwork. Chemically, turquoise is a hydrated copper/aluminum phosphate, of aggregate, cryptocrystalline structure. There is only one known deposit, in the state of Virginia, where turquoise is found in transparent to translucent visible crystals. Specimens from that locale are rare and bring a hefty price from collectors. More typically, turquoise is found as an opaque deposit in nodules, or veins within host rocks, or as shallow crusts on the surface of rocks.
Care and Use: As a gem material turquoise has its limitations: it is relatively fragile, porous, and susceptible to heat and/or chemical damage. Turquoise averages 18 – 20% water content and, as the gem is heated, (perhaps from an unwary jeweler’s torch,) that water is progressively lost until at 400 degrees C, the structural integrity of the mineral is destroyed.
