It has been nearly a century since Marcel Tolkowsky revolutionized diamond cutting with the original Ideal Cut Diamond. The brilliance of an independently certified, 1 carat Tolkowsky® princess-cut diamond delivers awe-inspiring style in this solitaire ring for her. The fine jewelry ring is secured by platinum prongs on a 14K white gold band. All Tolkowsky® princess-cut diamonds are certified Ideal Cut and each ring comes with a certificate of authenticity. The ring comes with a unique presentation box.
