Vintage Sterling Green Peekaboo Earrings

These vintage earrings are made of Mexican sterling silver and have simple hooks. Each earring is shaped like a long, curved tear drop with mirrored cutouts. The cutouts are filled with what appear to be black and green stones, though I'm unable to confirm what kind. I've seen earrings by the same maker that have the cutouts filled with turquoise, but I'm not sure this is the same. The backs of the earrings are stamped "925 FA-109 (?) Mexico". There is some tarnishing and one of the hooks might be slightly askew, but there are no issues that affect wearability. Dimensions: 34x12mm Weight: 7.97g Love the piece but not the price?
