Physical properties
Hardness 7 on the Mohs scale; translucent to colorless with a vitreous luster and hexagonal crystal structure. The piece is rough and irregular, so cleavage is not evident; quartz has no true cleavage and commonly fractures conchoidally.
Formation & geological history
Quartz forms in many geological settings, including silica-rich igneous rocks and hydrothermal veins; its age cannot be determined from the image. The crystal has been shaped or selected and wire-wrapped for jewelry.
Uses & applications
Primarily worn as a pendant or kept as a decorative mineral specimen.
Geological facts
Quartz is one of Earth’s most abundant minerals and is also used in electronics for its piezoelectric properties.
Field identification & locations
The clear, glassy appearance and lack of cleavage are consistent with quartz, though a photograph cannot confirm the identification. Quartz occurs worldwide; comparable wire-wrapped pendants commonly sell for about $5–$30 USD.
