Very 1980s New York, I think these earrings (while difficult to photograph) are fantastic. Really three earrings in one, they can be worn as simple silver diamond shapes, or with either or both larger diamond shaped layers underneath--one black with silver stripes, the other solid black. (See the third photo for view of the 3 component parts of each earring). 

The earrings are in very good used condition, with a bit of discoloration to the bottom black layer only in the area covered by the silver top layer, so not visible when worn. 2" long x 1.25" wide at largest.
