Kasena Stone Armband, Ghana

Warm cinnamon brown with chalky scars, like a loaf that survived the oven.

This armband is Kasena, from Northern Ghana, West Africa. It is granite. Granite is a hard, coarse-grained igneous rock, and shaping it into a ring requires patient grinding and polishing with abrasives. Rounded ring in russet and tawny brown, its surface patched with white mineral flecks along the inner edge and lower right. The outline is a little flattened, and the opening is wide and uneven. It is 0.5 inches deep and 4 in diameter.

Weathered, freckled, and entirely comfortable in its skin.
