Physical properties
Hardness: 7 (Mohs scale), Color: iridescent/rainbow over clear to white, Luster: Vitreous to metallic, Crystal Structure: Trigonal/Hexagonal, Specific Gravity: 2.65
Formation & geological history
Formed naturally as clear quartz in hydrothermal veins, then subjected to a lab process called chemical vapor deposition where metals like gold, silver, or titanium are bonded to the surface.
Uses & applications
Primarily used for decorative purposes, crystal healing, metaphysical collecting, and costume jewelry.
Geological facts
The iridescent finish is not natural; it is created by placing natural quartz in a vacuum chamber and heating it to extreme temperatures while introducing metallic vapors.
Field identification & locations
Identify by the rainbow 'oil slick' luster that covers the natural crystal facets. Commonly found in gem shops and spiritual markets. Note that the rainbow sheen is a surface layer and can be scratched off, unlike natural iridescence in minerals like labradorite.
