Weathered quartz-rich rock, possibly milky quartz

Quartz (SiO₂); the specimen may be massive vein quartz, but its identity is uncertain from the photo

AI-generated identification · may be incorrect

Pale gray-white to tan, rough and granular with a glassy-to-dull luster; quartz has Mohs hardness 7, a trigonal crystal structure, and no cleavage. The image does not show enough detail to confirm whether other minerals are present.

AI Estimated Value

About $1–$10 for a common, unpolished specimen of this size; higher value would depend on confirmed identity and quality.

Physical properties

Formation & geological history

If quartz-rich, it likely formed as silica-rich fluid cooled in a rock fracture; such veins occur across many geological ages and settings.

Uses & applications

Quartz is used in glassmaking, electronics, and decorative objects; attractive pieces may be polished or collected.

Geological facts

Quartz is one of Earth’s most abundant minerals and commonly occurs in veins and many rock types.

Field identification & locations

Look for hardness sufficient to scratch glass and absence of cleavage; a closer view or simple tests would be needed to distinguish quartz from a quartz-rich rock. Quartz occurs worldwide.
