Shell button

1 of 2 mall domical button (of which 2 found, see: Notes) of Spondylus shell with V-shaped perforation in base. All in excellent condition. Two beads: the larger has its interior hollowed out by means of a hole bored through the centre and then extended by four more holes drilled at an angle beside it. The first hole is drilled right through the apex of the button, and is flanked on the exterior by two small holes filled with shaped pieces of hard stone.
