Kasena Stone Armband, Ghana

Slightly lopsided, wholly sincere, and dressed in smoky brown.

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. Broad ring with a softly irregular outline and a slanted inner wall. The finish is satiny dark brown with pale flecks near the opening, and the inner edge shows tiny chips and a faint seam. It is 0.5 inches deep and 3.6 in diameter.

Hand-shaped roundness is a negotiable concept.
