Diamond Rings - READ DETAILS

I have four engagement/wedding rings I’m willing to part with (family heirlooms) if the value is right. I do plan on taking these rings in to be appraised, but I’m posting them here in case anyone buys and sells diamonds and is able to appropriately test and value them before I get around to taking them in. You really do need to be able to test them because there’s a chance one of the rings has fake diamonds from stories I’ve heard. I have a minimum I’m willing to take for them, and if they are valued below that, I’ll just keep them. The listed price is a placeholder and not necessarily what I’m looking for. The rings are all different metals. Yellow gold, 18k white gold, and one might be platinum. One is unmarked. One ring is also missing a stone. Please only message if you are able to examine the rings and make an honest offer. I expect to sell them at a discount, but I don’t want to be ripped off either.
