Vintage Sterling Silver Black Onyx Southwestern Modernism Square clip Earrings Stunning large squares in sterling silver with a large square onyx stone. I can not test the stone but it does appear to be onyx. Large 1980 to 1990 design with a clip earring back. Amazing earrings that are high quality and heavy. No marking that I can see and can be shinned up nicely. Tested sterling silver. I think the stamps were removed when converted to clips.
