Thank you Monnie! I will go out for it tonight. My first brilliant idea (mostly favored because it meant I didn't have to leave the house) was to try using nail polish as glue..sometimes I have to roll my eyes at myself.
I'm fond of G-S Hypo Cement. It is non-yellowing and for rhinestones & watch crystals and has a needle to dispense the glue out of. I'm using it right now in fact, fixing an antique rhinestone pearl clasp. Handy stuff!
