Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise shape, casting a slender, luminous silhouette that seems to stretch beyond the finger. This semi-set solitaire invites a fixed two-tone an 8 x 4 mm marquise diamond, poised to become the centerpiece of a quietly striking design.

Crafted in a fixed two-tone blend of warm 18k yellow and 18k yellow and platinum and cool 18k yellow and platinum, the band balances softness with architectural contrast. The low-profile setting ensures the ring sits comfortably beneath daily wear, while the polished finish reflects the Brooklyn studio’s meticulous handwork.

Each piece embraces the clarity and sustainability of lab-grown diamonds, a mindful alternative that honors both beauty and ethics without compromise.

Designed for those who appreciate subtle drama, the slender marquise shape elongates the hand gracefully, pairing effortlessly with stacking bands or worn alone for a refined statement. Its comfort fit and modest height make it glove-friendly and ideal for everyday life.

Resizing is available to ensure a perfect fit, with careful attention to preserving the integrity of the two-tone metalwork.
