Antique 3.05 Carat Old Mine Cut Diamond & Emerald Platinum Engagement Ring

Centering on a large 3.05 Carat, chunky and scintillating antique old mine cut diamond, this Art Deco inspired engagement ring is a show stopper. Encased in a platinum, milgrain-studded bezel and surrounded with rich, green emeralds, this important jewel retains a bit of history. We rescued this old world sparkler with whose large facets reflect even a candle's light from an old worn ring and revitalized it by making this Jazz Age style masterpiece. With J color and Si1 clarity, meaning you will own a diamond of very high quality in a bespoke wedding or cocktail ring hand made by a ghost jeweler for Cartier that will endure for a lifetime.
