Sterling Silver ring with a piece of the Cape Sea Urchin. The sea urchin pieces are hardened with resin so they can last forever. 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. The sea urchin pieces are between 10-15mm wide. Please specify your ring size and preferable sea urchin colour.
