Physical properties

Hardness: 7 on Mohs scale; Color: Pale pink to peach; Luster: Vitreous to greasy; Crystal Structure: Hexagonal (Trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65.

Formation & geological history

Formed through the cooling and crystallization of silica-rich magma or from hydrothermal veins. This specific specimen has been water-worn and smoothed, likely in a river or coastal environment, over thousands of years.

Uses & applications

Used in landscaping, as a pocket stone for spiritual/decorative purposes, and in jewelry (though usually higher clarity specimens). Ground quartz is used in glassmaking and abrasives.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. The pink hue in quartz pebbles like this is often caused by trace amounts of titanium, iron, or manganese, or minute inclusions of dumortierite.

Field identification & locations

Identify in the field by its hardness (it will scratch glass) and lack of cleavage. Commonly found in riverbeds, glacial till, and along beaches where tougher minerals survive mechanical weathering.
