The Oppenheimer Blue was the largest blue diamond to ever appear at auction. It was named in honor of its previous owner; Sir Philip Oppenheimer. With its perfect hue, proportions and wonderful rectangular shape. Our connoisseur blue is a ring inspired by the beauty and shape of that perfect diamond; but not the price tag. Crafted from sterling silver, plated in yellow gold and set with an impressive 14.22ct blue Diamondeau® - flawless simulated diamond, and a scattering of 50 classic Diamondeau® - flawless simulated diamond across the mount.
