Part of our in-house EB line that incorporates antique and vintage diamonds into modern, minimal settings of our design. This ring has a beautifully faceted and unusually elongated 0.45 carat marquise diamond that was probably cut in the 1920s. It's set east-west in a platinum and 18K yellow gold mounting of our design. Made in New York.
