Sterling silver necklaces in assorted shapes with pieces of the Cape Sea Urchin. The sea urchin pieces are hardened with resin so they do not wear and tear at all. Every sea urchin is unique in its own shape and shade so every ring is unique in its own way. You can even bring me your very own sea urchin that you picked up on a special occasion. These sea urchin pieces range from 15 to 25mm wide and hang on a 50cm chain. Please specify your preferable sea urchin colour and shape, and size.
