Hi this is my first post and I'm hoping someone can help id my beautiful hand etched tray full of ornate detail please? It's definitely hand carved or etched as the ornate detail is different throughout the tray and there's no ghost marking (sorry don't know he name of that) to the back which to me, would show it's been impressed? Im hoping I've listed this in the correct area as in fairness, I don't know its origin, ( I think maybe either middle eastern or eastern?) and I don't have a clue about the script or markings on the back. I'm not even 100% sure if it's silver, it's not magnetic so it may be? I don't want to get it tested as that will mark it and I'm loath to do that with such a beautiful item, there is a lot of patina on the back and front of this stunning tray and areas of light iridescence but it hasn't been cleaned in years. Any info would be greatfully received, thanks
