Sea glass (likely pale blue glass)

Human-made silicate glass, likely soda-lime glass; not a natural mineral or rock

AI-generated identification · may be incorrect

Frosted, translucent pale blue, rounded and smooth from abrasion; glass has no Mohs hardness rating as a mineral (typically about 5–6), no crystal structure, and conchoidal fracture when broken. The image alone cannot confirm its composition.

Physical properties

Frosted, translucent pale blue, rounded and smooth from abrasion; glass has no Mohs hardness rating as a mineral (typically about 5–6), no crystal structure, and conchoidal fracture when broken. The image alone cannot confirm its composition.

Formation & geological history

Likely discarded glass weathered and tumbled by waves, sand, or gravel over years to decades; it is human-made rather than a geological formation.

Uses & applications

Collected and used in jewelry, mosaics, and decorative crafts; value depends on color, size, shape, and provenance.

Geological facts

The frosted surface develops as abrasion and chemical weathering etch the glass. Sea glass is distinct from naturally occurring minerals and beach-worn stones.

Field identification & locations

Look for uniform color and glassy translucence beneath the frosted, rounded surface; common on shorelines near historic settlements. A small common piece like this is typically worth about $1–$5 USD.
