Sterling Silver and Round Metal Plate Vintage Modernist Earrings
These are some of my favorites. The black metal is textured with a geometric pattern and they are removable if you're inclined to put them on larger hoops.
The metal piece is just under 1" in diameter
The sterling silver hoop has a diameter of 1.25
Condition: one of the hoops has a slight bend in the back, it's behind the metal part so not exactly noticable. Good vintage condition.
