New additions to the urchin collection Maria Apostolou 8 years ago The new larger sea urchin measures 1.6 x 1.6 x 0.8 cm. For this pendant, I soldered a bezel cup and set a 4mm garnet cabochon. The pendant was finished with black platinum plated sterling silver ball chain. Large and medium size urchin pendants. Don’t you think that the urchin also looks great combined with fluorite? Last, these are new custom versions of the urchin and fish bracelets with sterling silver clasps. Thanks for visiting!
