In many cultures the seashell is considered a lunar symbol. As the tides rise and fall the shells are displayed by the ocean and then taken back again. As the ocean always renews itself, so seashells are always highly energized. In Christianity the snails, mussels, and seashells are seen as the resurrection. Many cultures used seashells as currency. Shells are sometimes used as a fertility symbol, and were used to adorn the high priestesses and priests of various cultures. The wearer of the seashell talisman often will not relate to the material world and as a matter of fact, may not have many worldly possessions. Interestingly, people that wear seashells also seem to have an affinity for whales, porpoises, and all sea life.
