These Necklaces are made out of a whole baby sea urchin embedded in a pendant. The whole sea urchin are hardened with resin so it cannot damage. Every sea urchin is unique in its own shape and shade so every pendant 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 pendants are between 10 and 15mm wide and they hang on a 45cm chain. Please specify your preferable sea urchin colour and shape.
