These are vintage earrings from an estate collection. They're Native American-made, and they're made out of sterling silver and green malachite semi-precious gemstones. The earrings are stamped "sterling." They are signed, but I'm unable to identify the specific Native American jewelry designer. Each earring measures 0.4" by 0.75" They're in excellent condition, and have been cleaned and sanitized. They will come in a gift box.
