In creating this necklace and earring set I incorporated 4 mm round and 18 x 9 mm elongated oval chrysocolla beads and sterling silver findings including 3 mm faceted beads, 4 mm round beads, ear wires, Bali spacer beads and a spring ring clasp. The necklace is nearly 18" in length and the earrings are 1 1/4" plus the ear wires. Chrysocolla is often found with Malachite and Azurite. These beads vary from dark green to lighter green to dark blue. The supplier said the beads were Chrysocolla but they may be dyed Jasper. Either way, they are beautiful Beads.
