Hi Chique,
I agree. The thing to do is search on eBay for similar gold jewelry, add those listings to your "watch list" there, and then wait and see how the bidding goes for them.
With the recent increase in gold prices, there have been some companies starting to advertise that they will buy unwanted jewelry - you just mail it to them in an envelope and they pay you (I believe) based on karat and actual weight.
I'm a little suspicious of those companies. They are obviously making a profit, or their business plan wouldn't work. I'd definitely try to sell the jewelry as jewelry before selling it as gold to be melted down. Jewelry is nearly always much more valuable as jewelry than as its component metal.
It's difficult to say whether you'd have better luck selling the jewelry as a set or individually. That often depends on the jewelry designs. Sometimes you can include a less-desirable piece with more-desirable ones and make more money overall, even though the buyer really wants the more-desirable pieces.
As for price, you could always list them at the appraised price on eBay and see what happens. If they don�t sell, you can list them again for a little lower, and keep going from there until they sell. I would definitely state in the item description that the jewelry has been appraised for X amount, and whether you can include the appraisal papers with the sale.
I'm curious to see how things go. If you have a chance, please post again and let us know how it's going!
