Hey, if there is no markings that does not mean its not silver, or even gold! If its old sometimes the stamp can be worn off. Or if it was resized the 925 could of been removed. The shiny plain one is that the one that has the weight?
Well went to the local jeweler & had the rings looked at. Turned out to be all copper rings & the diamond ring is costume jewelry. Oh well I got my best bang when I dug them up. Maybe next time will be the real deal. LOL Hope everyone else is more lucky on there finds this weekend. Hopefulgold still looking with my AT Pro.
