I've bought a few pieces from ebay. Some sellers are genuine, but unfortunately I've had my fair share - or even an unfair share - of mis-sellers. I've had to return a number of items where descriptions as 'silver' are incorrect. I use a certain set of criteria, such as ensuring that the words '925 Silver', 'Sterling Silver' and never just 'silver' or 'silver metal'.

To qualify for refunds it is necessary to return the item using registered mail, not just with a requirement for signature (ebay regulations). These days, this postal charge weighs in at over £6, paid for by the buyer, returning the goods (i.e. me!!). It is a significant loss on not buying anything!! Caveat emptor.
