Physical properties

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.
