Why We Love It

Based on one our all-time favorite antique finds, this ring incorporates vintage elements such as oxidized metal, delicate side stones, and plenty of prongs. The absolutely gorgeous old mine cut at the center is bright and beautifully-faceted, catching all of the light thrown its way. She has an incredible spread to her for a big and glamorous look. A team-favorite, for sure.

The dimensions of the center stone are 9.58 x 8.84 x 4.93 mm.
