Of the organic shell beads, a small percentage of them are cut shell beads and not all of them were as uniform as the microperforated cut shell beads; the beads that do not display the use of technologically advanced techniques were shells of Tridacna rolled into a barrel shape. The microperforated cut-shell beads are generally less than 2 mm in diameter, and thus appear to require a great amount of effort and technique to produce; these can thus be said to belong to the Metal Age. The microperforated cut shell beads were studied to have
