Neither of them, possibly
Frustrating Stuart, as we all know, but is it even worth bothering to discuss the matter? I could scream at times with these descriptions............. but ebay either doesn't have the time or isn't bothered about policing this market, and probably all you'd get from the sellers is a mouthful of abuse.
My own opinion is ................ both C20 probably - the first listing might have been made almost anywhere, but the second may well be a certain Italian island, bearing in mind what appears to be gold coloured inclusions.
just my opinions of course - but we've been down this road before, and nothing ever changes.
