Ring has 925 stamped inside and China which I tried to capture in a couple of the photos. It’s gold toned so likely gold plated 925. But the gold plating is wearing off as this is an older ring. The band definitely has some wear. But I do not see any visible major flaws on the stones with the naked eye and nothing appears to be loose or missing. I believe these are CZs.
