This is a pair of Designer signed “Sarah Cov” silvertone metal clip-on earrings. These are very unique as they are convertible by removing the center and flipping it over. One side of the center is black and the other is white. These are very retro! They measure about 1 3/8” in diameter. And like any piece of jewelry that has removable parts, the parts are easily lost, so it is rare to find all the pieces in tact in a vintage piece.
