I have seen plates with such rims - and more complex insides, for sale in TKMaxx, they were made in Murano Italy, (or at least, that's what it said on their labels!) and another maker of similar plates, mostly square in shape, but in a pale green (window type of glass), made by Portmeirion in England.
Sorry, I can't help more than that. I don't know the maker of yours, but I still suspect it is very recent.
