18k yellow gold and black onyx and enamel ring. This beautiful statement piece features a stunning and sophisticated design. The centerpiece of the ring is a square-shaped black onyx plaque, which is surrounded by detailed scroll engraving and framed in a striking black enamel border. The wide shoulders are also bordered with black enamel, featuring more intricate scrollwork engraving that adds to the ring's overall appeal. On each shoulder, a marquise-shaped black onyx perfectly ties the entire design together.
