In creating this necklace and earring set I selected 10 x 6 mm rondelle chrysocolla beads, a 30 x 22 mm puffed oval chrysocolla bead as a center drop focal point, 6 mm sodalite beads and sterling silver findings including 3 and 4 mm Bali beads, 4 mm round beads, ear wires and a toggle clasp. The necklace is 20" in length and the earrings are an inch plus the ear wires. The supplier said the beads were Chrysocolla but they may be dyed Jasper. Either way, they are beautiful Beads.
