My daughter and I used to hunt for shells on the beach when she was little and found a giant limpet shell which I have always kept and was my inspiration for this design.  The elegant oval shape is so flattering to wear.  
The limpet shell and links in the bracelet are cast in sterling silver with a toggle closure.  Standard length is 7 3/4" and I can adjust the size in 1/2" increments if you need it smaller or larger, see length options at check out.
