Judith Jack Marcasite Amber Lever Back Earrings

Judith Jack Amber marcasite genuine silver Amber lever back earrings. These earrings have been used and do show some signs of wear, there are a couple little marcasites missing. There is also an area that has a small piece of glue. I purchased them like this, I have no clue why someone placed glue on the earring. It is just on one small area.
