Vintage Coro Open Sphere Earrings

These vintage earrings by Coro are made of a silver tone metal and have screw backings which are stamped Coro. The top section of the earrings looks to be modelled after a pin backing or a push pin of some kind, while the bottom section is a dangling sphere with a horizontal cylinder cutout. There are signs of gentle wear, but nothing that affects current wearability. Pardon the pictures, the sphere bits are very reflective. Dimensions: 29mm x 9mm Weight: 9.04g
