Picked up on the shore of Maine. I know you've done this as you try to capture and keep a memory. This one was then put in a mold so that every little detail was captured and then casted in 10k, 14k or sterling silver. Give it a keepsake or for yourself as a talisman of long hot summer days on a charm necklace. Maybe you already have one to add it to or if you need a chain to get one started. I recommend my Classic Box Chain. Makes a sweet gift.
 
This is a listing just for the spiral shell.
