Tumbled sea glass or pale-green quartz pebble

Indeterminate from image; possibly quartz (SiO₂), but the smooth translucent piece may be man-made glass

AI-generated identification · may be incorrect

Small, rounded, translucent pale-green/clear piece with a glossy, wet surface; hardness and crystal structure cannot be determined visually. Quartz is Mohs 7 with a hexagonal crystal system; glass has no crystal structure.

Physical properties

Formation & geological history

Could be naturally water-worn quartz, formed in silica-rich geological settings, or discarded glass rounded by water; the image does not establish which.

Uses & applications

If quartz, it may be used for jewelry or collecting; sea glass is mainly decorative or crafted into jewelry.

Geological facts

Rounded edges can result from prolonged abrasion in water, but both natural pebbles and glass can acquire this appearance.

Field identification & locations

A scratch test or examination for bubbles and conchoidal fracture can help distinguish glass from quartz; the specimen is too ambiguous to identify confidently from this photo.
