Bead store (or similar) in the area?

I need to get a clasp on a necklace replaced, really simple, the kind of thing that's cost me about five bucks at various bead stores over the years. Last time I went to Boston Bead Company in Harvard, but they've apparently closed. Anybody know of a local place that could do such a thing? I'm striking out on google.
