Physical properties

Hardness: 7 on Mohs scale; Color: Translucent to milky white or pale pink; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (trigonal); Cleavage: Indistinct; Specific Gravity: 2.65.

Formation & geological history

Formed through the cooling of silica-rich magma or from hydrothermal solutions. It can be found in igneous, metamorphic, and sedimentary environments across all geological ages.

Uses & applications

Used in the production of glass, ceramics, and electronics (due to piezoelectric properties). Varieties like rose or smoky quartz are popular for jewelry, lapidary work, and spiritual collections.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Historically, it was used to craft tools and arrowheads because of its conchoidal fracture which produces sharp edges.

Field identification & locations

Identify in the field by its hardness (it can scratch glass), lack of cleavage, and conchoidal (shell-like) fracture patterns. Frequently found in stream beds, mountains, and desert environments worldwide.
