Dary's is what shopping in Paris is all about -- a wonderful cavern of Ali Baba popular with artists, actors, models, and jewelry lovers. It's run by the Dary family, with Katherine -- a gemologist and author of a book on collecting jewelry -- on hand to help. You'll need to take your time though, because the walls are filled with row upon row of antique jewels from every era, more modern secondhand jewelry, and drawer upon drawer of antique one-of-a-kinds. Métro: Tuileries.
