Physical properties
Hardness of 7 on the Mohs scale, vitreous to metallic luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65. Features an iridescent, rainbow-like metallic sheen on the surface due to a chemical vapor deposition coating.
Formation & geological history
Formed through a human-made laboratory process where natural quartz crystals are heated to high temperatures in a vacuum chamber and bonded with vaporized precious metals such as gold, platinum, or titanium.
Uses & applications
Widely used in crystal healing, holistic practices, decorative items, and jewelry making.
Geological facts
Also known as Angel Aura, Aqua Aura, or Opal Aura depending on the specific metal used for the coating. The iridescent effect is a result of optical interference from the microscopically thin metal layer.
Field identification & locations
Easily identified by its characteristic metallic, rainbow sheen covering a crystalline quartz base. Commonly found in metaphysical shops and rock and mineral shows worldwide.
