A one-of-a-kind warm old mine cut diamond, in a classic wide band with softly squared corners. Brushed, glowing gold contrasts the brightness of the antique diamond, beautifully displaying its asymmetric, organic shape, with the large open culet characteristic of antique cut stones. 

Interior of the ring is solid and curved for a comfortable fit. 

14k gold with a brushed finish, set with a mid 1800s old mine cut natural diamond. 0.43 ct, N VS2. Ring weighs 10.0 g.

Size 6 1/2, resizable within 1 size (up or down). 7.6 mm width in front, tapers to 3.4 mm. 

Cast and crafted locally in Los Angeles, ready to ship.
