Physical properties

Hardness: 7 (Quartz basis); Colors: iridescent rainbow, white, blue, green; Luster: Vitreous to metallic (treated); Crystals: Hexagonal (Quartz), cubic/massive (others).

Formation & geological history

Quartz and Sodalite are natural minerals formed in igneous and metamorphic environments, but the bright iridescent specimen is human-processed through Physical Vapor Deposition (PVD).

Uses & applications

Predominantly used for ornamental purposes, crystal healing collections, jewelry, and decorative hobbyist items.

Geological facts

The rainbow specimen is 'Aura Quartz', created by bonding titanium or gold atoms to the surface of natural quartz crystals in a vacuum chamber. The collection also includes blue Sodalite and clear Quartz.

Field identification & locations

Commonly sold in gift shops and crystal boutiques. While the location near the Poland-Czech border (Sudetes region) is rich in natural agates and quartz, these specific tumbled specimens are commercial trade items.
