Holly Golightly knew that few things in life generate more excitement than a little blue box from Tiffany. This company sells all the fine-jewelry classics—diamonds, gemstones, pearls, gold, and silver--with designs from basic to elaborate, suitable for all occasions. Make sure to see Tiffany's own Mark line of watches, with prices averaging $2,000. Also available are tableware and home accents, including traditional crystal, china, and sterling silverware.
