Vintage 925 Sterling Silver Navajo Chandelier Earrings, Natural Blue Turquoise

Vintage authentic Native American Indigenous Navajo earrings. Chandelier style. Handmade. With natural blue turquoise stones. Each earring is stamped 925 on the back and has a makers mark. Covered with a very old vintage patina. I don't want to clean it as that will reduce the collector's value of the item.
