Physical properties
Hardness: 7 (Mohs scale), Color: iridescent pink and gold gradient, Luster: Vitreous to metallic (due to coating), Crystal structure: Hexagonal/Trigonal via quartz host.
Formation & geological history
Natural quartz crystals are formed in hydrothermal veins. These specific specimens are then treated in a vacuum chamber where vaporized metals (like titanium, gold, or cobalt) are bonded to the surface.
Uses & applications
Metaphysical and decorative use, jewelry making, and crystal collecting.
Geological facts
While the base is natural quartz, the striking colors are man-made. The process is known as 'metal vapor deposition' and is permanent. Different metals produce different colors (e.g., gold for Aqua Aura, titanium for Flame Aura).
Field identification & locations
Identified by high-intensity iridescence and rainbow reflections not found in natural untreated quartz. Look for the natural quartz crystal shape beneath the metallic sheen.
