Physical properties

Hardness: 7 Mohs scale; Color: Iridescent blue, purple, and gold; Luster: Vitreous/metallic; Crystal Structure: Trigonal; Cleavage: None/Conchoidal fracture.

Formation & geological history

Formed through a human-industrial process called vapor deposition; natural quartz crystals are heated in a vacuum and bonded with vaporized precious metals like titanium, gold, or cobalt.

Uses & applications

Primarily used for decorative purposes, jewelry (pendants and rings), and in metaphysical or holistic practices.

Geological facts

While the base is natural quartz, the iridescent sheen is created by a thin layer of metal atoms. Different metals produce different colors: 'Titanium Aura' (blue/multi) or 'Aqua Aura' (bright turquoise).

Field identification & locations

Identify by looking for natural crystal growth patterns beneath an unnaturally vibrant, metallic oily-slick surface. Common in new age shops and mineral shows rather than geological field sites.
