For many years now I have been on a mission, to find the perfect sea shell to cast as a necklace. I have spent hours (and days) wandering along seashores looking for just the right shape. I am fascinated by the interior curved spine of shells, the spiral within. I had to find a shell just the right size, with the spine intact and of just the right spiralness. Last March I finally found it. I carried this shell with me very carefully. I filed down the outside core to showcase the perfect spine. From this model I made a mold and cast the perfect shell into sterling silver magic.
