This fun necklace is made of black jasper chips, sterling silver beads and a Paua Starfish Pendant. It measures almost 20 inches plus a 1.5" extender finished with an accent jasper chip. The sterling silver clasp is an easy-squeeze kind, where you squeeze both raised parts to open the clasp (no messing with finger nails). All metal materials are sterling silver except for the tiger wire (coated cable) used to string the beads on. The starfish pendant is definitely coated in some sort of acrylic material that sort of magnifies the paua shell, and it measures approx. 1.5". You can wear the necklace two different ways as shown (untwisted and twisted). SOLD
