Price listed is for four pair of earrings. These are approximately 14mm by 10mm flat back crown settings with post backs. These are unplated. We are selling them cheap because whatever solder was used has cause an oxidation or calcium? build up around the posts. ON SOME OF THE PIECES IT IS A FAIRLY SMALL SPOT ON THE BACK AND ON OTHERS IT COVERS MORE THAN HALF OF THE BACK OF THE SETTING. These will need to be cleaned or possibly plated or enameled. If you just want to use the settings you can just clip off the posts. Both the settings and the posts are brass.
