Koma Stone Armband, Ghana

Greyer than its siblings in the dark-ring trade, with a bold diagonal scratch.

This granite armband is Koma, from Northern Ghana, West Africa. A band cut from solid stone is heavy and smooth, and its simple circular form changes little from one maker to the next. Thick circular band in cool slate grey with a finely grainy surface. A straight incised line crosses the upper left, and a few smaller nicks mark the outer curve. The opening is round and fairly smooth. It is 3.75 inches wide, 3.75 deep and 0.75 high.

Cold grey stare, scratched but not remotely bothered.
