Thanks for the info! My brother and sister-in-law are both in the jewelry business, though they produce it (my brother makes sterling and dichroic glass jewelry, the sister-in-law has her own sterling line, with a patented process for adhering enamel/paint to the surface). Even worked the gem and jewelry shows in Tucson for six years! It's a blast, if you ever get down there, usually the last week of January, first week of February.
I'll have to look around, and see what I can find out. We have a few jewelers here in town, not sure what they charge for appraisal fees, though.
