Mineralogical Identity & Physical Constants: Turquoise is a hydrated basic copper and aluminum phosphate mineral with the chemical formula CuAl₆(PO₄)₄(OH)₈·4H₂O. Its vibrant blue color is produced by trace copper (Cu²⁺) cations within the cryptocrystalline aggregate lattice. Under gemological testing, it exhibits a spot refractive index of 1.61 to 1.65, a specific gravity of 2.60 to 2.85, and a Mohs hardness of 5.0 to 6.0.

Cultural Legacy & Traditional Context: Known across ancient cultures as a talisman of safe travel and protection, and revered in Indian lapidary traditions as Firoza Ratna, Turquoise holds an iconic status. In traditional Vedic astrology, Firoza is frequently selected for Jupiter (Guru) and Ketu-related practices. It is also celebrated worldwide as the traditional December birthstone. It is customarily mounted in Sterling Silver (925 Silver), Panchdhatu, or yellow gold bezels for rings, pendants, and bracelets.
