Physical properties

Hardness: 7 (Mohs scale); Color: Clear base with iridescent or deep blue coating; Luster: Vitreous to metallic; Crystal system: Hexagonal; Cleavage: None/Conchoidal fracture.

Formation & geological history

Formed as natural quartz crystals in igneous or metamorphic environments, then artificially enhanced in a vacuum chamber by bonding metallic vapors (like cobalt, gold, or silver) to the surface.

Uses & applications

Primarily used for decorative purposes, crystal healing, metaphysical collections, and jewelry making.

Geological facts

The vibrant blue color is not natural to the quartz specimen; it is created via a process called physical vapor deposition (PVD). This specific deep blue variation is often marketed as 'Cobalt Aura' or 'Aqua Aura'.

Field identification & locations

Identify by looking for a natural hexagonal crystal structure paired with a 'too-perfect' or surface-only color distribution that often shows an iridescent peacock-like sheen. Unlike blue glass, quartz will scratch glass and have a higher density.
