Green Cats Eye and AB Earrings

Large oval green cats eye stone dangle earrings. Gold tone antiqued look on these ear wired and the bezel set stone, so I am unsure of the metal that these are. Estate sale item and don't know anything more about these. Measures about 1-1/2 inch from top of wire down to bottom of earring. The cats eye stone area alone is about 1/2 inch in height. Pretty small round aurora borealis stone located above the cats eye. I am calling these used because of buying from the estate sale, I really don't know if these were ever worn or not.
