Physical properties

Hardness: 7 (Mohs scale) for core; Color: Iridescent rainbow, metallic blue, purple, and gold; Luster: Vitreous to metallic; Crystal Structure: Trigonal/Hexagonal; Cleavage: None

Formation & geological history

Natural quartz crystals are placed in a vacuum chamber where vaporized titanium and other metal oxides are bonded to the surface via electrostatic charge (CVD process). Base quartz can be millions of years old.

Uses & applications

Metaphysical use, jewelry, ornamental decor, and collective items for crystal enthusiasts.

Geological facts

The rainbow effect is created through a laboratory process called Magnetron Ion Sputtering; while the quartz is natural, the iridescent appearance is man-made.

Field identification & locations

Identify by its intense, unnatural neon-rainbow metallic sheen and distinctive hexagonal crystal point. Found globally as clear quartz, but treated in labs in the USA, China, and India.
