Polished black stone carving, likely soapstone/steatite
Steatite (massive talc), Mg₃Si₄O₁₀(OH)₂; exact material cannot be confirmed from the image
AI-generated identification · may be incorrectDark gray to black, polished, opaque, and waxy to vitreous; typically massive rather than visibly crystalline, with Mohs hardness about 1–2 and poor cleavage. The smooth carved form and very low apparent porosity are consistent with soapstone, though other black stone may be possible.

Physical properties
Dark gray to black, polished, opaque, and waxy to vitreous; typically massive rather than visibly crystalline, with Mohs hardness about 1–2 and poor cleavage. The smooth carved form and very low apparent porosity are consistent with soapstone, though other black stone may be possible.
Formation & geological history
Steatite forms by hydrothermal alteration of magnesium-rich ultramafic rocks, commonly during Precambrian to younger metamorphic events. This appears to be a human-carved and polished geological specimen, not a natural rock surface.
Uses & applications
Soapstone is used for carvings, ornaments, countertops, stove linings, and heat-resistant objects; this piece is primarily decorative or collectible.
Geological facts
Talc-rich soapstone is unusually soft and can be scratched easily with a fingernail or copper coin. Dark polished carvings are also sometimes made from serpentine, basalt, jet, or dyed stone.
Field identification & locations
Common sources include Brazil, India, Finland, Canada, and the United States. Test inconspicuously: genuine steatite should scratch readily and feel slightly greasy; avoid destructive testing if valuable.
