Cosma Oval Diamond Ring

Cosma Collection The Cosma Collection explores a more intuitive approach to setting, where the design begins with the diamond’s natural silhouette. Rather than limiting the stone to what is visible from above, each ring is sculpted to reflect and honor its full form. The setting mirrors the diamond’s shape, allowing it to live beyond the surface and become part of the overall structure. It’s a study in balance, where gold and stone move as one continuous expression, revealing the diamond in its entirety rather than just its crown. Crafted in polished 18K gold, our Cosma Ring is designed to emulate the oval diamond silhouette in an octagon bezel setting. - The image shown features a 2.5ct G VS1 GIA certified ethically mined oval cut diamond set in 18K gold. -
