Hey guys, I'm looking for a certain ring. Apparently my girlfriend saw it while on holiday and loved it, and it's our anniversary in dec so I want to get her it. I went to the only jeweller in my small town and there was nothing like it there, so I'm having to look online but have no idea what to search for. I'm in the UK, but just knowing what name it goes by would be useful! Apologies for the vague description. It's a sort of stone. Mainly white with a marbled look. Shiny texture. This is all the way around the ring. It's cross section is a slight dome, not straight. It has a thin metal border on both sides, which was gold but not as important. Would really appreciate any help you could give
