Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette across the hand. This semi-set three-stone ring invites your choice of a 10 x 5 mm marquise center, poised to emphasize architectural clarity and modern confidence.

Crafted in cool platinum, the mounting balances strength with refined minimalism. Each prong is meticulously shaped to secure the stone while maintaining a low-profile setting that sits comfortably for daily wear. The three-stone arrangement offers subtle symmetry, enhancing the center’s tapered drama without excess.

Our lab-grown diamonds reflect a commitment to ethical jewelry, reducing environmental impact while delivering exceptional clarity and brilliance.

Designed for those who appreciate structured elegance, this ring complements slender fingers and pairs effortlessly with stackable bands or a wedding band. Its comfort fit and modest height make it glove-friendly and ideal for an active lifestyle.
