There are only a couple of A jaffe ring owners here and I don't know how often they're on PS. also, I know many vendors are getting ready for the big Vegas show so designers can be a bit backed up. What is your jeweler telling you? I'd call them and ask them to check on the status of your ring.
I got mine a year ago - only took a few weeks (standard mount, no custom changes, etc). Have your jeweler call Jaffe if they haven''t already. Also, Jaffe does reply to e-mail - I have e-mailed them (their address is on their website), so perhaps drop them a line?
