This bead shop is a bit small in terms of square-footage, but have a huge array of products crammed into their small space. They sell beads made from semi-precious (natural stones) and glass beads, too. Lots of seed beads and lots of "findings". Everything is displayed in an organized and attractive fasion, it's enjoyable to browse there. The staff is very friendly and helpful and the store also offers classes. They handle sterling silver and gold-filled chain, wire, and findings, as well. Check out this shop before you drag yourself all the way to baubles-and-beads in Berkeley, there is a good chance you won't need to look further!
They also can make custom jewelry for you (if you're not inclined to make it yourself) and do repairs.
