Physical properties
Hardness of 7 on Mohs scale, white to translucent color, vitreous to greasy luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms abundantly in hydrothermal veins, pegmatites, and igneous, metamorphic, and sedimentary rocks across geological time scales.
Uses & applications
Used in glassmaking, abrasives, electronics, ornamental items, and mineral collecting.
Geological facts
Milky quartz is the most common variety of quartz found on Earth, often appearing white due to microscopic fluid or gas inclusions trapped during crystal growth.
Field identification & locations
Easily identified by its high hardness (scratches glass), white color, and lack of cleavage; found globally in almost all geological environments.
