Physical properties

Hardness: 7 on Mohs scale; Color: Clear to white/cloudy; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (trigonal); Cleavage: None/Conchoidal fracture.

Formation & geological history

Formed through the crystallization of magma or hydrothermal deposition in veins. It is one of the most abundant minerals in the Earth's crust and can be found in almost all geological environments.

Uses & applications

Used in glassmaking, abrasives, electronics (piezoelectric properties), and as a popular gemstone or collector's item.

Geological facts

Quartz is highly resistant to both chemical and physical weathering. It is the main component of most beach sands.

Field identification & locations

Identify in the field by its hardness (it can scratch glass and steel) and its lack of cleavage. This specific specimen appears to be a small, weathered fragment or grain.
