Physical properties
Hardness: 7 (Mohs scale), Color: Iridescent multi-colored (pink/blue/gold), Luster: Vitreous to metallic-sheen, Crystal Structure: Trigonal/Hexagonal
Formation & geological history
Natural quartz crystals formed in hydrothermal veins, subsequently enhanced via Magnetron sputtering or Chemical Vapor Deposition (CVD) where metallic vapors fuse to the surface.
Uses & applications
Metaphysical jewelry, crystal healing, decorative display, and collectible unique aesthetics.
Geological facts
Unlike dyed crystals, the color in aura quartz is bonded at a molecular level with metals like titanium, gold, or silver in a high-pressure vacuum.
Field identification & locations
Identified by unnatural neon or rainbow gradients and a high metallic sheen over natural hexagonal crystal habits. Often found in Arkansas, Brazil, and China.
