I believe that are goldplated and real turquoise.
please post pics of the back side of the earrings, as well as any marks.
Thank you Big Bear. I hope you can see the photo. The back of the earrings with a “symbol” R TH or is that a KR TH? I think it is a symbol because it looks like an X with a center line.
I will send a second picture. With the front.
