Details
Turquoise is a prized opaque, blue-to-green mineral, chemically a hydrated copper and aluminum phosphate . Formed in arid regions via groundwater reacting with copper/minerals, it has a 5–6 Mohs hardness, waxy luster, and often features dark brown/black matrix veins. It is popular for jewelry, talismans, and December birthstone, cherished for its color and spiritual symbolism.
