Physical properties
Hardness 7 on Mohs scale; opaque white with earthy or waxy luster; conchoidal fracture; lacks cleavage; specific gravity ~2.65.
Formation & geological history
Formed through hydrothermal crystallization in igneous veins or metamorphic pegmatites, then rounded and weathered by fluvial action.
Uses & applications
Commonly used in landscaping, road aggregate, silicon extraction, and occasionally tumbling or ornamental lapidary work.
Geological facts
Milky quartz gets its cloudy white appearance from millions of microscopic gas or liquid bubbles trapped during rapid crystallization.
Field identification & locations
Identified by hardness (readily scratches glass), milk-white hue, and resistance to chemical weathering; abundant worldwide in gravel beds and stream deposits.
