Physical properties
Pale pink to peach, rough and opaque-to-translucent with a vitreous luster; quartz has Mohs hardness 7, a trigonal crystal structure, and no cleavage. The small, worn specimen is not diagnostic enough to confirm its identity from the image alone.
Formation & geological history
If quartz, it formed as silica crystallized in igneous or hydrothermal settings; its rounded shape suggests weathering and transport. Quartz occurs in rocks spanning much of Earth’s geological history.
Uses & applications
Quartz is used in glassmaking, electronics, and abrasives; attractive pink material is cut or polished for jewelry and ornaments.
Geological facts
Quartz is among Earth’s most abundant minerals and commonly survives erosion because it is hard and chemically durable.
Field identification & locations
Look for hardness (scratches glass), glassy fracture, and lack of cleavage; rose quartz commonly occurs in pegmatites and quartz veins. A small, common pebble is typically worth about $1–$10 USD.
