Possible sea glass (naturally frosted glass), not a confirmed geological specimen

Man-made silicate glass; composition varies, commonly soda-lime glass

AI-generated identification · may be incorrect

Pale green-gray, rounded and matte-frosted, with no visible crystals or cleavage. Glass has variable hardness (about 5–6 Mohs) and is amorphous; the image alone cannot confirm its material.

Physical properties

Pale green-gray, rounded and matte-frosted, with no visible crystals or cleavage. Glass has variable hardness (about 5–6 Mohs) and is amorphous; the image alone cannot confirm its material.

Formation & geological history

Likely discarded glass abraded by waves or weathering over time; it does not have a geological age. A naturally occurring stone with a similar appearance cannot be ruled out from this photograph.

Uses & applications

Collected as beachcombing curios or used in crafts and jewelry; not normally used as an industrial mineral specimen.

Geological facts

Sea glass gets its frosted surface from prolonged abrasion and chemical weathering in water or soil.

Field identification & locations

Its smooth, rounded edges and uniformly frosted surface suggest sea glass, but check for conchoidal fracture and glassy translucence; a hardness or streak test may help distinguish it from stone. Common on shorelines near historical settlements.
