Iridescent polished/tumbled stone (likely coated quartz or glassy synthetic material)
Indeterminate; possibly quartz (SiO₂) with an artificial iridescent coating
AI-generated identification · may be incorrectSmall, rounded, highly polished object with mirror-like multicolored sheen; apparent hardness and crystal structure cannot be determined from the image. The uniform spherical shape and vivid surface suggest a coated or manufactured specimen rather than a naturally formed crystal.

Physical properties
Small, rounded, highly polished object with mirror-like multicolored sheen; apparent hardness and crystal structure cannot be determined from the image. The uniform spherical shape and vivid surface suggest a coated or manufactured specimen rather than a naturally formed crystal.
Formation & geological history
If quartz, it formed from silica-rich hydrothermal or igneous fluids; the visible rainbow effect likely comes from thin-film coating or surface treatment applied after shaping. Geological age is indeterminate.
Uses & applications
Used mainly as a novelty, decorative, or metaphysical collectible; not suitable for construction or jewelry identification without testing.
Geological facts
Iridescence can result from interference in a thin coating, fracture surfaces, or metallic films; it is not diagnostic of a particular mineral.
Field identification & locations
Check with a loupe for coating wear, bubbles, seams, or glass-like conchoidal fractures; test hardness cautiously and inspect specific gravity. Common natural quartz is widespread, but this exact object may be a commercial craft sphere.
