This demantoid garnet ring, cast from fine platinum, was modeled after an original Retro Era ring. Our goal was to recreate this ring with many of same techniques that were used during the 1940's and 50's in order to achieve the delicacy and intricacy of true Retro Era rings.

We adore the many details on this ring! From the milgrain, to curvaceous, substantial lines, to the glittering diamond accents. We paid careful attention to all the details of a true Retro Era rings, while still being mindful of wearability! Corner prongs hold the garnet securely in place, while also keeping the round stone in the geometric theme of the rest of the ring. The demantoid garnet is a rare variety and has a brilliant fire amongst the vibrant olive green. Just gorgeous!
