AI Appraisal Estimate

A small, dark green, carved stone figurine in the shape of a hippopotamus. It shows some surface wear and white markings.

This appears to be a hand-carved stone figurine of a hippopotamus. The dark green stone suggests it could be jade or a similar hardstone. The white markings on the surface seem to be scratches or possibly remnants of a finish. The craftsmanship appears fairly simple, and without any artist's signature or provenance, it's likely a decorative item rather than a significant work of art. The value is primarily based on the material and the appeal as a decorative object. Assuming it is indeed carved from a type of jade or hardstone, and factoring in the wear and lack of identifying marks, an estimate can be provided.
