1. Cut a 1 1⁄2-in. (3.8cm) piece of beading wire. String an opal briolette, a microcrimp bead, and the loop of a ring form. String the other end of the wire through the microcrimp in the opposite direction, making a small loop. Crimp the microcrimp bead and trim the excess wire. Make a second opal unit, if desired.
