Physical properties

Hardness: 7 on Mohs scale; Color: Iridescent blue and purple; Luster: Vitreous to metallic; Crystal structure: Hexagonal; Cleavage: None/Conchoidal fracture; Specific gravity: 2.65.

Formation & geological history

Natural quartz forms in hydrothermal veins or pegmatites; however, the vibrant colors are created by an artificial process called vacuum deposition, where thin layers of metal vapors (like gold, indium, or titanium) are bonded to the surface.

Uses & applications

Mainly used for decorative purposes, crystal healing, metaphysical practices, and as inexpensive jewelry components.

Geological facts

While the base material is a natural mineral formed over millions of years, the 'aura' effect is entirely man-made. It is often marketed under various names like Aqua Aura or Rainbow Aura depending on the metals used.

Field identification & locations

Identify by the unnatural ombre color shift and metallic sheen on the surface of common quartz. It is not found in the wild with these specific neon colors. Found in 'new age' shops and gem shows worldwide.
