Physical properties
Mohs hardness of 7, white to translucent color with a cloudy appearance, vitreous to greasy luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms primarily from hydrothermal veins and cooling magma chambers through the precipitation of silica-rich fluids over geological time.
Uses & applications
Commonly used in jewelry, ornamental carvings, glassmaking, and metaphysical collections.
Geological facts
Milky quartz is the most common variety of the quartz family and gets its cloudy color from microscopic fluid inclusions trapped during crystal growth.
Field identification & locations
Easily identified by its milky-white opacity and high hardness that scratches glass. It is found worldwide in virtually all geological environments.
