Vintage Ruby Red and Clear Stone 12KGF Screw

Casual wear to night out--these earrings are simple yet elegant. True vintage screw back earrings. 1/20 12K Gold filled with clustered ruby red and clear stones. Somewhere along the line the screw was replaced--which is shown by the M&S and Phyllis hallmark. Approximately .5" x .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. Please see all photos and do not hesitate to ask questions.
