Avowed flea-market junkie and jewelry designer Katherine Wallach (212/724-9260; from $650) is giving fresh meaning to the term "lucky charms." Her whimsical creations incorporate coral trinkets collected on sourcing expeditions throughout Europe. More traditional, though no less dramatic, are Wallach's silver or gold pendants and cuff links made with stones she found on beaches around Italy. Wearing one of her baubles is the next best thing to going on a treasure hunt yourself.
