Physical properties
Hardness: 7 (Mohs), Color: Rainbow iridescent sheen over clear or pale crystals, Luster: Vitreous to metallic, Crystal Structure: Trigonal/Hexagonal, Specific Gravity: 2.65
Formation & geological history
Natural quartz crystals formed in igneous or metamorphic environments, later subjected to a human-made process called vacuum deposition where metallic vapors (like titanium or gold) bond to the surface.
Uses & applications
Metaphysical healing, jewelry making, home decor, and mineral collecting
Geological facts
The iridescent coating is only a few atoms thick, creating an optical phenomenon called thin-film interference. Although the coating is man-made, the underlying crystal is a natural geological specimen.
Field identification & locations
Identified by the distinct oil-slick or rainbow iridescence on the faces of quartz crystals. To ensure it is not glass, check for natural growth striations on the crystal faces and its ability to scratch glass.
