Kasena Stone Armband, Ghana

Honey-brown and faintly streaked, with a pale crease where the light lands.

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 in mellow brown tones, its surface softly polished and marked by light scratches and thin pale veins. Cream-coloured lines run down both sides of the band, and the opening is nearly circular. It is 0.5 inches deep and 4 in diameter.

Gentle colour, firm shape, no fuss.
