It has been nearly a century since Marcel Tolkowsky revolutionized diamond cutting with the original Ideal Cut Diamond. A resplendent, 1 carat Tolkowsky® round brilliant diamond creates timeless style in this solitaire ring for her. Platinum prongs secure the center stone, and a 14K white gold band completes the elegant look. This Tolkowsky® round brilliant diamond is certified Ideal Cut with the Hearts & Arrows Pattern and each comes with a certificate of authenticity and a unique presentation box.
