Identification

Name: Aqua Aura Quartz

Scientific classification: Treated Quartz (Surface-Coated)

Hardness: 7 Mohs

Transparency: transparent

Lustre: vitreous to metallic surface sheen

Crystal system: Trigonal

Primary colour: Iridescent Blue

Secondary colour: Blue

Colour family: Blues

Uniform surface iridescence and coating concentration at facets/edges distinguish treated aura quartz from natural blue quartz.

Verification Status

Status: verified-core-fields

Reference priority: GIA, Gem-A, Mindat, International Gem Society

Core identity, locality, and physical-property fields reviewed against standard gemological references.

Values are reported as practical gemological ranges where appropriate.

Principal mining regions: Base quartz commonly from Brazil and Madagascar; coating treatment performed in lapidary/manufacturing facilities

Important commercial sources: Aqua aura is a treated product, not a distinct natural locality gemstone

Historical significance: A modern treated-quartz product in contemporary gem trade.

Common treatments: Vacuum-deposited metallic coating is the defining treatment.

Synthetic or imitation forms: Coated glass and synthetic quartz also sold under aura-style names.

Common look-alikes: Coated glass, dyed quartz, titanium-coated quartz variants

Jewellery uses: Used in decorative jewellery, beads, and metaphysical market products.

Care recommendations: Quartz core is durable, but coating can be scratched; avoid abrasives and harsh polishing.

Formation

Natural quartz crystal is coated in controlled high-vacuum processing to create a thin-film interference effect.

Origin

Aqua aura is a treated product, not a distinct natural locality gemstone

Uses

Best for: Used in decorative jewellery, beads, and metaphysical market products.

Ideal uses: Pendants, earrings, and display pieces where coating is protected from abrasion.
