A small horseshoe crab handcarved, cast, and assembled complete with a moveable tail.  The charm is approximately 3/8 inches (0.9 cm) wide by 3/4 inches (2 cm) long and available in sterling silver or 14K gold.  The sterling silver one is also oxidized to show its details.  Looks great on a necklace or a charm bracelet.  The chain in the photo is sold separately.
