Sterling silver marcasite black enamel clip on earrings

These are definitely an art deco inspired pair of earrings. They are black enamel that have an onyx look when you're not up close. There are marcasite that outline the triangular shape. The bottom of the earrings are articulated and have a heart cut out on the back. They are 1 inch long. They are marked 925 and test positive for sterling silver. These are set with just enough tension where they stay on and don't pinch your ears. Please check photos and feel free to ask questions. Thanks for looking ❤️
