Likely clear quartz pebble or glassy quartz fragment

Quartz (silicon dioxide, SiO₂)

AI-generated identification · may be incorrect

Pale translucent to colorless, vitreous luster, and probably an irregularly rounded/tumbled form. Quartz has Mohs hardness 7, trigonal crystal structure, no cleavage, conchoidal fracture, and specific gravity about 2.65.

Physical properties

Formation & geological history

Could be naturally weathered quartz from an igneous or metamorphic source, or a polished/tumbled specimen; the image does not resolve diagnostic crystal faces. Quartz formed in igneous rocks, hydrothermal veins, and metamorphic environments over a wide range of geological ages.

Uses & applications

Common quartz is used in glass, ceramics, abrasives, electronics, and construction aggregate; clear attractive pieces are sold as decor or inexpensive specimens.

Geological facts

Quartz is one of Earth’s most abundant minerals and is piezoelectric. The rounded outline and bright highlights could also indicate man-made glass, but the specimen is treated here as geological material as requested.

Field identification & locations

Check for natural conchoidal fracture, hardness sufficient to scratch ordinary glass, and absence of bubbles or perfectly uniform molded surfaces; common worldwide, especially in stream gravels and quartz veins.
