Physical properties
Hardness of 7 on the Mohs scale, pale pink to rose-pink color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Formed in igneous pegmatites and hydrothermal veins, often weathered out and rounded into pebbles by wave action in beach or river environments over thousands to millions of years.
Uses & applications
Used in ornamental carvings, gemstone jewelry, decorative items, and metaphysical practices.
Geological facts
The pink color is typically caused by trace amounts of titanium, iron, or manganese, or microscopic fibers of pink dumortierite embedded within the quartz structure.
Field identification & locations
Easily identified by its conchoidal fracture, pink coloration, and inability to be scratched by steel (hardness 7). Commonly found in beaches, rivers, and pegmatite deposits worldwide.
