Physical properties

Hardness: 7 on Mohs scale; Color: Clear to white (clear quartz) and pink (rose quartz); Luster: Vitreous (glassy); Crystal structure: Hexagonal/Trigonal; Cleavage: None (conchoidal fracture); Specific gravity: 2.65

Formation & geological history

Formed through the cooling of silica-rich magma or from hydrothermal veins. These specimens are found in various geological environments ranging from igneous pegmatites to metamorphic rocks.

Uses & applications

Used in electronics (as oscillators), glassmaking, abrasives, and widely in jewelry for gemstones, beads, and metaphysical collecting.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Rose quartz gets its color from trace amounts of titanium, iron, or manganese. Piezoelectricity is a unique property of quartz where it generates an electric charge under mechanical stress.

Field identification & locations

Identify in the field by its hardness (will scratch glass but not be scratched by steel), glassy luster, and lack of cleavage planes. Commonly found in mountain ranges and riverbeds globally.
