The Davis Square Community

Firestone and Parson's in the back bay (on Newbury) provides appraisals, but there is usually a fee. You might start by going to a couple of pawnbrokers and getting an on-the-spot offer that will at least give you low-end ball park figure(s), then you can decide if it is worth paying an appraiser and selling to an antique (or simply used) jewelry store.
