Judith Jack Vtg Sterling Marcasite Drop Earrings

I adore Judith Jack and have a large collection. These are amazing vintage because the top stud moves & dangles. That dangle is unusual for vintage JJ. They are a combination of clear Swarovski crystal and marcasites in a geometric diamond pattern. I lost a tiny marcasite at the very top of one of the earrings. I am hoping that an artist can fix, or a JJ lover will purchase.
