Physical properties

Hardness: 7 on Mohs scale; Color: Pale pink to tan/clear; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (trigonal); Cleavage: Indistinct/Conchoidal fracture; Specific Gravity: 2.65

Formation & geological history

Formed through the cooling of silica-rich magma or from hydrothermal veins. This specimen shows a rough, sub-angular shape typical of field-collected minerals that have not yet been heavily water-worn.

Uses & applications

Used in glassmaking, abrasives, electronics (piezoelectric properties), and as a gemstone in jewelry or for metaphysical collecting.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Its name comes from the German word 'Quarz' and is known for its ability to generate an electric charge when mechanically stressed.

Field identification & locations

Identify in the field by its hardness (it will scratch glass), its lack of cleavage (it breaks into curved, shell-like pieces called conchoidal fractures), and its glassy luster. Common in granitic rocks and desert environments.
