Likely milky quartz or quartz-rich mineral fragment

Quartz, silicon dioxide (SiO₂)

AI-generated identification · may be incorrect

Typically colorless to white and translucent with a vitreous luster, irregular fracture, and no cleavage; Mohs hardness 7 and specific gravity about 2.65. The specimen appears pale, translucent, and freshly broken, though the image is insufficient for precise identification.

Physical properties

Formation & geological history

Forms in igneous, metamorphic, and hydrothermal environments as veins, cavity fillings, or rock-forming grains; quartz ranges from Precambrian to modern geological ages. Common sources include Brazil, Madagascar, the United States, and worldwide quartz-bearing rocks.

Uses & applications

Used in glass, ceramics, electronics, abrasives, and engineered stone; attractive pieces may be cut or polished for décor and jewelry.

Geological facts

Quartz commonly shows conchoidal fracture and can scratch ordinary glass. Its cloudy appearance usually results from microscopic fluid inclusions or fractures.

Field identification & locations

Check whether it scratches glass, lacks cleavage, and has a glassy fracture; a streak test should be white. Confirmatory identification may require hardness, density, and crystal examination.
