Quartz-rich pebble (likely milky quartz)

Quartz, silicon dioxide (SiO₂), possibly a weathered quartzite fragment

AI-generated identification · may be incorrect

White to gray, translucent patches, vitreous-to-dull luster, and no obvious cleavage; quartz hardness is Mohs 7 and specific gravity about 2.65. The rounded, irregular shape suggests natural abrasion or a tumbled fragment.

Physical properties

Formation & geological history

Most likely derived from quartz veins or quartz-rich metamorphic rocks and rounded in stream or coastal sediments. Quartz formed in many geological settings and ages; the photograph cannot establish a precise age.

Uses & applications

Common quartz has low commercial value as a small specimen, though quartz is widely used in glass, ceramics, electronics, abrasives, and engineered stone. Attractive clear or crystalline pieces may be collected.

Geological facts

The specimen resembles milky quartz, whose cloudiness comes from microscopic fluid inclusions and fractures. It could also be a pale quartzite or another light-colored silicate rock; the image is insufficient for a definitive identification.

Field identification & locations

In the field, test with a steel file or knife: quartz should resist scratching, while glass or softer rocks scratch more readily. Quartz pebbles are plausible around southeastern Victoria, including the reported region, but a hand lens and hardness/streak tests would improve confidence.
