Green glassy slag or manufactured glass bead
Noncrystalline silicate glass; likely industrial glass/slag, not a true mineral
AI-generated identification · may be incorrectTranslucent vivid green, vitreous luster, rounded/tumbled form with bubbles and flow-like internal textures. Hardness is approximately 5–6 Mohs; no cleavage and no crystal structure. The bright uniform color and vesicles strongly suggest glass rather than a natural gemstone.

Physical properties
Translucent vivid green, vitreous luster, rounded/tumbled form with bubbles and flow-like internal textures. Hardness is approximately 5–6 Mohs; no cleavage and no crystal structure. The bright uniform color and vesicles strongly suggest glass rather than a natural gemstone.
Formation & geological history
Probably melted and rapidly cooled industrial glass or furnace slag; its geological age cannot be assigned. It may also be a recycled-glass decorative pebble, though the specimen is clearly glassy and human-processed.
Uses & applications
Used as decorative aggregate, jewelry cabochons, beads, and art glass. It has little value unless confirmed as a rare historic slag or attractive collectible glass.
Geological facts
Green color commonly comes from iron, chromium, or copper; trapped bubbles and curved conchoidal fractures are diagnostic of glass. It is not emerald, jade, or peridot.
Field identification & locations
Inspect for perfectly smooth conchoidal surfaces, bubbles, flow bands, and uniform color; these distinguish it from crystalline minerals. Natural green minerals usually show crystal grains, cleavage, or variable inclusions.
