Worth getting it checked to see if that's gold, but I very much doubt it... and I don't see any marks.
I think this is just vintage costume jewellery perhaps bordering on ‘antique’ in base metal, although it may be gilded. The Grecian urn with dancing ladies is almost certainly moulded glass and not carved from anything. This one (being offered at just under $50) has an identical panel in black glass with the relief portions highlighted in enamels to give it the appearance of a bronze urn:
Great... but are you sure it's not gilded or plated? It would be unusual for solid gold of that era to be unmarked, although the missing attachment with the pin might have provided a more suitable surface for marking.
Nice Find!!! I have seen Egyptian Tourist Pieces that looked very similar to that. It may have a mark that's in Arabic. I didn't see any mark but I have seen some tourist pieces that were not marked.
