Physical properties
Hardness: 7 (Mohs scale), Color: iridescent multi-color rainbow, Luster: metallic/vitreous, Crystal structure: hexagonal/trigonal prisms, Cleavage: none (conchoidal fracture)
Formation & geological history
Natural clear quartz crystals undergo a process called vapor deposition in a vacuum chamber, where metallic titanium and niobium atoms are fused to the surface at high temperatures.
Uses & applications
Primarily used for decorative display, metaphysical practices, and jewelry components.
Geological facts
The rainbow effect is caused by thin-film interference, similar to oil on water; though the coating is man-made, the underlying crystal is natural earth-mined quartz.
Field identification & locations
Identify by the vibrant rainbow sheen that does not scratch off easily; found in metaphysical shops rather than natural geological outcrops.
