This pair of vintage Aldo Cipullo clip-on earrings, crafted in 18k gold, features a bold design combining onyx and diamonds. Each earring is centered with a domed cabochon onyx, surrounded by a halo of 18 round brilliant-cut diamonds, adding a touch of brilliance to the deep black stone. The outer edge is framed with a polished onyx border, creating a striking contrast with the gold and diamonds. Due to the natural characteristics of onyx, the earrings are not perfectly symmetrical, highlighting their unique craftsmanship. Circa 1970s, they are signed “A. Cipullo” and stamped “18k,” confirming their authenticity. Weighing 21.5 grams in total, each earring measures 1" x 1" (2.54 cm x 2.54 cm), making them a standout accessory.
