Physical properties

Hardness: 7 (Mohs); Color: Naturally clear to white, dyed bright teal/blue; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (trigonal); Cleavage: None; Specific Gravity: 2.65

Formation & geological history

Formed through hydrothermal processes in igneous and metamorphic environments. This specific specimen has been tumbled in a machine and treated with artificial pigments to enhance its color, which has pooled in surface fractures.

Uses & applications

Decorative purposes, metaphysical/crystal healing, children's pocket stones, and costume jewelry.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Brightly colored stones like this are often dyed 'crackled' quartz, where the stone is heated and quenched to create fractures that absorb dye.

Field identification & locations

Identify in the field by high hardness (scratches glass) and conchoidal fracture. For dyed specimens, look for concentrated color in cracks and pits where the dye has settled, unlike natural color which is usually more even.
