Sterling silver signed marcasite stud earrings vintage

Fabulous! Stunning vintage marcasite sterling silver stud earrings well made and high end. They are designer and signed but as much as I tried I couldn't make out the signature. These will complement any outfit. Please check out my other listings I just listed a gorgeous coral clover and marcasite pendant that these would look fabulous with! They didn't come with backs but I added brand new sterling butterfly backs to them. Happy to bundle. would wear well with the marcasite and coral clover pendant I'm offering. or I have a bracelet with marcasite and a ring or two please search current listings or message.
