Likely quartz-bearing rock (possibly milky quartz or quartzite)

Quartz, silicon dioxide (SiO₂); exact identification is limited by the small photograph

AI-generated identification · may be incorrect

Pale lavender-white, rough and slightly translucent with a vitreous to dull luster; quartz has Mohs hardness 7, no cleavage, conchoidal fracture, and specific gravity about 2.65. The grainy texture may indicate quartzite or a quartz-rich fragment.

Physical properties

Formation & geological history

Quartz crystallizes from silica-rich hydrothermal fluids or igneous melts; quartzite forms when quartz sandstone is metamorphosed. Formation ages range from ancient Precambrian to geologically recent depending on locality.

Uses & applications

Common quartz is used in glass, ceramics, abrasives, electronics, and engineered stone; attractive pieces may be collected or cut as decorative material.

Geological facts

The lavender tint could reflect trace iron, inclusions, or surface staining, but it is not enough to confirm amethyst. A scratch test and close inspection of crystal faces would improve identification.

Field identification & locations

Look for glassy luster, absence of cleavage, and resistance to scratching with a steel knife; quartz should scratch ordinary glass. Common worldwide, especially in hydrothermal veins, pegmatites, and quartz-rich metamorphic rocks.
