Twentieth Century Ltd.

Thousands and thousands of costume-jewelry pieces populate the cabinets at this subterranean Charles Street space. Collectible Chanel earrings and Miriam Haskell pins are here, but the real draws are the neatly labeled trays of coral necklaces, engraved lockets, and pearl studs. Don't miss the bins of $10 steals.
