Vintage Coro Green Tri

Vintage three stone screw back earrings. Forrest green colored gemstones set in gold tone metal. In great condition for age. Marked Coro on screw. Screw back design. Approximately .5" Note: Most of my jewelry is pre-loved. I only wipe down jewelry. I do not deep clean any jewelry before shipping. I am not a professional and do not want to risk damaging any vintage item. I will note any flaws/defects. Lighting might affect the colors in the photos. I will try to describe as accurately as possible. Please see all photos and do not hesitate to ask questions.
