Physical properties

Hardness: 7 (Mohs scale), Color: Multicolored/Iridescent, Luster: Vitreous/Metallic, Crystal Structure: Hexagonal prism, Cleavage: None/Conchoidal

Formation & geological history

Natural quartz crystals are placed in a vacuum chamber and heated, while vaporized precious metals (like titanium, gold, or silver) are introduced to bond with the surface through electrostatic charge.

Uses & applications

Primarily used in jewelry, metaphysical practices, chakra healing, and as decorative collector items.

Geological facts

While the base material is natural quartz, the iridescent 'aura' effect is a man-made enhancement. Different metals produce different names, such as 'Angel Aura' (silver/platinum) or 'Titanium Aura'.

Field identification & locations

Identified by unnatural rainbow surface reflections on a standard quartz crystal shape. Genuine quartz bases will scratch glass, though the thin metallic coating can be rubbed off over time with heavy wear.
