Selling a piece of fine jewelry. I don't know how to do it.

2. Call and ask a few jewelers, they might do it for free.

It can be a positive to help their reputation and maybe you'll come back and buy something -- those are reasons they might do it.

If there is any way you can get the weight of the gold, it'd at least give you the "melt" value of the gold. Tough to do obviously with the saphires mounted.

If the saphires are a good quality, I'd try googling for saphire values and see what comes up -- might get you in the ball park at least.
