If its any help we had a heavy pendant that i got the mrs when we were younger. It just sat there doing nothing as i'd bought her some much better stuff recently. Anyway we had it valued and were told the top money it would achieve and the best way to sell it is at auction. We watched near on identical stuff on ebay for weeks and stuff wasn't selling or achieving the money. We had the pendant and a few rings weighed at several places and after laughing in their faces at some silly offers we weighed it all in for the best money we could get.

We could have got more at auction but it's a gamble if the right people aren't about on that day. Plus you've got the fees to pay out of it. We took a hit and just turned it back into cash. Its a shame but its all worth more in weight and yellow gold just isn't as popular.
