It continues to astound me the amount of misrepresentation or lack of basic knowledge I see in Auction houses in identifying items they sell, and not just about beads.

This is a good one, an item being represented as a antique enamel on glass necklace.
In what world does that even remotely look like enamel on glass.
On the flip side, knowledgeable buyers can sometimes get a good deal.
