Where to trundle if you want to wear that pretty pierced stone you found on your first anniversary hike up Mount Diablo? The Bead Store has a vast assortment of necklace-ready cords, and the Castro shop's friendly staff can point you toward a nice clasp, or even tie a slip-knot for you if you're not fancy. It's the city's smallest and oldest bead store — it has been in the same spot since 1964 — and stocks centuries-old beads and rare stones you won't find anywhere else, as well as the standard tools you need to take your diamonds from the rough.
