Physical properties
Hardness of 7 on the Mohs scale, white to translucent color with a greasy to vitreous luster, trigonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed through the precipitation of silica-rich hydrothermal fluids within veins, pegmatites, and cavities under high temperatures and pressures.
Uses & applications
Used primarily in mineral collections, ornamental carvings, and occasionally as a source of high-purity silicon for industrial applications.
Geological facts
Milky quartz is the most common variety of crystalline quartz found globally, often containing microscopic fluid inclusions that give it its cloudy appearance.
Field identification & locations
Easily identified in the field by its distinct white color, lack of cleavage, and high hardness capable of scratching glass. Common worldwide and highly plausible for the Brazilian region.
