Silver + Black Large Clover Stud Earrings

No metal marking that I can see, bought from a local boutique. Good condition, as shown, feel solid and heavy, not flimsy. Obviously look a great deal like the infamous Van Cleef earrings bc of the similar clover shape. They fit like an oversized stud, taking up most of the lobe. Very preppy, clean, and minimalist. Tried to show size by holding them against my hand.
