The broken, fresh surfaces display a distinctly glassy to slightly greasy sheen typical of massive hydrothermal vein quartz.The jagged, irregular breaks and lack of planar stepping indicate a mineral without cleavage, highly consistent with quartz.The dark schistose/metasedimentary inclusion visible in the wet photo and the reddish-brown iron-oxide coatings are classic for vein quartz found in Arizona. Milky quartz is the most common variety of crystalline quartz (silicon dioxide). Its white, cloudy, or translucent appearance is caused by minute fluid inclusions of gas or liquid trapped during the crystal\'s formation. It commonly occurs in hydrothermal veins, pegmatites, and as residual erosion cobbles in arid environments.
