Ivory jewelers

[librarybrandy.livejournal.com]

Are there any jewelers in the area (even further into Boston, if there's no one local) who work with/can fix ivory? I have a bracelet with a cracked bead, and I'd like to get the bead fixed somehow--or the bracelet restrung without it. Are there jewelers around who could do this? How much does something like that cost?

(Before anyone jumps on the "ivory is poaching and you're evil for owning it" train, I should point out that this is fossilized mammoth ivory; the animal very clearly was done using it several thousand years ago.)
