mineral

Green sea glass or green glass-like tumbled material

Amorphous silicate glass; likely anthropogenic soda-lime glass, not a natural mineral

AI-generated identification · may be incorrect

Translucent bright green, smooth rounded surfaces, and vitreous luster; glass has no crystal structure or cleavage and is typically Mohs hardness 5–6. The frosted surface and rounded edges suggest prolonged abrasion in water or tumbling.

Physical properties

Formation & geological history

Most likely weathered bottle or container glass formed by humans, then naturally or mechanically abraded; it is not a geological rock and has no geological age. A natural green mineral such as aventurine quartz is less likely because the specimen appears uniformly glassy.

Uses & applications

Collected as sea glass or used in crafts and jewelry; it has little industrial value as an individual fragment. Genuine rare sea-glass colors can be collectible.

Geological facts

Color commonly comes from iron, chromium, or copper-bearing glass additives. The specimen’s smooth, frosted texture and bubble-like inclusions are typical clues to glass.

Field identification & locations

Identify by checking for uniform conchoidal fracture, possible bubbles, lack of crystals, and consistent glassy translucence; natural aventurine quartz would show granular sparkle and greater hardness. Common on beaches, riverbanks, and around discarded glass sources.
