Physical properties

Formation & geological history

Quartz forms primarily from the cooling of magma or from hydrothermal veins. It is found in almost all types of geological environments and can date back billions of years depending on the host rock formation.

Uses & applications

Used in glassmaking, electronics (piezoelectric properties), jewelry (when faceted), and as decorative architectural stone or healing crystals in the metaphysical community.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Its name comes from the German word 'quarz', meaning 'hard'. It is highly resistant to chemical and physical weathering.

Field identification & locations

Identify in the field by its hardness (it will scratch glass), its conchoidal (shell-like) fracture, and lack of obvious cleavage. Found globally in riverbeds, pegmatites, and mountains.
