Found these beauties in a jewelry box from the goodwill dumpster! would love to know if they are valuable. I’ve done all the DIY tests, like rubbing them on my teeth, and touching them to my cheek, ect… they pass those simple tests. They have screw on backs with 14k marking as well as two other marks, a star and I think a Chinese symbol.The setting is very unique and I can’t find anything online that looks similar or with similar markings. I think they’re just gorgeous though and I wear them every day! I’ll post a few pics in hopes someone has any information that can help.
