Physical properties
Hardness: 7 (Mohs scale), Color: iridescent blue/purple/pink gradient, Luster: Vitreous to metallic iridescence, Crystal Structure: Trigonal, Cleavage: None
Formation & geological history
Natural quartz crystals are formed in hydrothermal veins. This specific specimen has been through a man-made process called vacuum deposition, where metallic vapors (like titanium or gold) are bonded to the surface.
Uses & applications
Primarily used in jewelry, home decor, and metaphysical/healing collections.
Geological facts
Aura quartz is a 'man-made' mineral variety; while the base crystal is natural quartz, the rainbow coloring is a permanent chemical bond of metallic ions created in a laboratory.
Field identification & locations
Identify by the intense rainbow sheen that does not occur naturally in this specific hue pattern on quartz points. Look for natural crystal terminations under the iridescent coating.
