Physical properties

Formation & geological history

Formed through the cooling of silica-rich magma or from hydrothermal veins. This specimen appears water-worn or tumbled, suggesting it was sourced from a secondary alluvial deposit or gravel bed.

Uses & applications

Used widely in glass making, abrasive manufacturing, electronics (piezoelectric properties), and commonly as decorative gemstones or 'healing crystals' in the metaphysical community.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Its name is derived from the German word 'Quarz' and the Polish term 'kwardy', meaning hard.

Field identification & locations

Identify in the field by its ability to scratch glass and its lack of cleavage (it breaks with curved, glass-like surfaces). It is found globally, notably in Brazil, Madagascar, and the United States (South Dakota and North Carolina). Collectors should look for translucency and color saturation.
