Physical properties

Hardness: 7 on Mohs scale (quartz base); Color: Iridescent rainbow (multicolored); Luster: Vitreous to metallic; Crystal Structure: Trigonal (Hexagonal prisms); Cleavage: None/Conchoidal fracture.

Formation & geological history

Natural clear quartz formed in pegmatites or hydrothermal veins, later enhanced in a vacuum chamber where vaporized titanium and other metal oxides are bonded to the surface via electrostatic charge.

Uses & applications

Primarily used in jewelry, as decorative display specimens, and in metaphysical practices (healing crystals).

Geological facts

The rainbow effect is caused by thin-film interference, similar to oil on water. While the coating is man-made, the underlying crystal is a natural geological mineral.

Field identification & locations

Identify by the vibrant, metallic rainbow sheen over a clear quartz crystal shape. Unlike natural peacock ore, the iridescence is a surface treatment on a hexagonal crystal. Often found in mineral shops rather than in nature.
