Fine silver sea urchin molded from a locally found urchin skeleton. The pendant measures approximately 25 mm (1 inch) in diameter. Note that these are individually made; the photographed pendant has sold but I have one more, slightly larger but essentially the same as these photos.
Shown with an 18" Argentium sterling silver curb chain and with a surgical silk suture necklace, sold separately. These and other necklace options can be found here
