Physical properties
Colorless to milky translucent crystal with a glassy luster and commonly irregular fracture; Mohs hardness 7, trigonal crystal structure, and no cleavage. The small specimen is wrapped in metal wire and worn as jewelry.
Formation & geological history
Quartz crystallizes from silica-rich fluids or melts in many geological settings; its formation may span a wide range of ages. The image does not reveal its specific geological source or age.
Uses & applications
Used in jewelry and collecting; quartz also has major industrial uses in glassmaking, electronics, and abrasives.
Geological facts
Quartz is one of Earth’s most abundant minerals and occurs in igneous, sedimentary, and metamorphic rocks.
Field identification & locations
A clear, hard, glassy appearance is consistent with quartz, but the wire wrap and image alone cannot confirm the identification. Quartz is found worldwide; the locality cannot be determined from the pendant.
