Twelve and a half inches, on a full one-inch handle, finished with a carnelian sphere rather than a point. Carnelian is a translucent orange-red chalcedony coloured by iron oxide, and one of the oldest worked stones on record — carnelian beads turn up in Indus Valley sites four and a half thousand years old. A sphere sits differently in the hand from a point, and reads differently in a room.
