Signed Judith Jack Marcasite Earrings

Bow marcasite earrings with a pearl (I’m guessing it’s a faux pearl, but I’m not sure; I believe she used faux pearls in her line). The back says, “sterling” on one side & , “J/J” on the other. I’m sure these are vintage but they are lovely. No stones missing. Smoke free, pet friendly home. Please feel free to ask questions
