The specimen is a polished sphere exhibiting a mottled appearance with varying shades of dark green, black, and some lighter greenish-brown or yellowish-brown areas. The surface is smooth and reflective, indicating a good polish. The color variations and patterns are characteristic of serpentine minerals, which often show a mix of dark and lighter green hues, sometimes with black inclusions or veins. The overall appearance suggests a metamorphic rock composed primarily of serpentine group minerals. The presence of lighter, somewhat fibrous-looking areas could indicate antigorite, while the darker, more uniform areas might be lizardite.
