Vintage Jade (Nephrite) earrings set in sterling silver

These earrings are set in sterling silver. They just need a polish. The stones are a type of Jade called Nephrite. They were my grandmother's. Purchased circa 1960. Dangling style. For pierced ears. My cousin who is a jeweler/gemologist unofficially appraised these for me- no paperwork. Must be able to come to my home to pick up.
