We could all use a little memento of the beach in our daily lives, if only to center us when the urban walls start closing in. And if a stringed necklace made up of shells is the way to do it, well, we're here for it. Puka shells are climbing their way back , so maybe it's time we give seashell jewelry a little reconsideration. But stash your repressed memories of Surfer Steve and his necklace back where they came from. Think of the resurgence as puka 2.0, featuring cowrie shells in their full form.
