Lonely Planet review for Beadworks
For the creatively inclined, Beadworks has all the components for making your own jewelry. Come here for the impressive selection of shiny gemstones, hand-painted beads and other delightful charms. Avid beaders agree that much of this stuff is overpriced; so treat yourself to a rare stone or a funky bead but look elsewhere to stock up on supplies. There's another shop in Harvard Sq.
