The shapes I use on my jewelry are free-form. I make them from beeswax and have them cast into metal (lost wax casting), each piece is perfectly imperfect. The circle of life is an approx. 1/2 inch diameter circle that can be use as a charm, strung on leather (at approx. 24") or on navy cord (includes a 10k gold lobster clasp). Made to order 6-8 weeks
