Physical properties
Hardness 7 on Mohs scale; displays vibrant, iridescent metallic rainbow colors including deep blues, purples, and teals; vitreous to metallic luster; trigonal crystal system; specific gravity around 2.65.
Formation & geological history
Formed as natural quartz through hydrothermal processes in igneous, metamorphic, or sedimentary environments, then artificially bonded with titanium atoms in a high-temperature vacuum chamber to create the iridescence.
Uses & applications
Used primarily in jewelry, decorative ornaments, crystal healing practices, and mineral collection.
Geological facts
Although the titanium coating is artificially applied in a laboratory, the base material is genuine natural quartz crystal. The vapor deposition process permanently bonds the metal to the surface of the quartz.
Field identification & locations
Can be identified by its natural quartz crystal habit combined with a distinct, brilliant metallic rainbow sheen. Widely available in gem shops and online rock retail outlets.
