Why we love it

The diamond's shape and faceting pattern are truly exceptional, unlike anything we've encountered before. Its softly beveled corners give it an octagonal outline, while the center boasts a distinctive old-mine cut charm, with vibrant bursts of color and fire. We decided to set this remarkable stone in a modified version of our open knot ring, adjusting the metal positioning to maintain the same fluid motion, leading to compass prongs for a one-of-a-kind ring.
