These are designed to contrast color, size and shape. I use them as an exercise in design, color and whimsy. They are strung with mostly glass beads. Each is strung on 49 strand beading cable, usually three strands. They are jewel length. Most have a copper clasp. I make them for fun and will continue to do so until I run out of beads or they bore me. They are $50 each with a $5.00 shipping charge, which you may purchase using PayPal.
