Clear quartz crystal beads
Quartz (silicon dioxide, SiO₂)
AI-generated identification · may be incorrectTransparent, colorless, glassy luster with faceted surfaces; quartz has Mohs hardness 7, a trigonal crystal structure, and no true cleavage. The image shows shaped beads, so their original crystal form is not evident.

Physical properties
Transparent, colorless, glassy luster with faceted surfaces; quartz has Mohs hardness 7, a trigonal crystal structure, and no true cleavage. The image shows shaped beads, so their original crystal form is not evident.
Formation & geological history
Quartz forms in many geological settings, including cooling silica-rich fluids in veins and cavities; it occurs in rocks of many ages. These pieces have been cut and faceted from natural material.
Uses & applications
Used in jewelry, decorative items, and collecting; quartz also has important industrial and electronic applications.
Geological facts
Quartz is one of Earth’s most abundant minerals and commonly forms six-sided crystals in nature.
Field identification & locations
Identify quartz by its hardness, glassy luster, and lack of cleavage; common sources include Brazil, Madagascar, and the United States. Faceted beads alone cannot confirm whether the material is natural quartz or imitation glass.
