Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc—like a whispered promise across the skin. This semi-set engagement ring frames a 12 x 6 mm marquise stone, poised to captivate with its tapered drama and graceful sparkle.

Crafted in a fixed two-tone blend of warm 18k rose and 18k rose and platinum and cool 18k rose and platinum, the band balances softness and strength. The solitaire setting is designed with a low profile, allowing the diamond to sit close to the finger for everyday wear without catching. Each curve is hand-finished in our Williamsburg studio, ensuring a smooth comfort fit that feels as natural as it looks.

Our commitment to ethical jewelry shines through the use of a lab-grown diamond, offering clarity and brilliance with a smaller environmental footprint. This ring suits those who appreciate refined romance and a statement piece that layers effortlessly with other bands or stands alone with quiet confidence.

Because the center stone is sold separately, you can select a marquise diamond that perfectly matches your vision. Resizing is available to ensure a seamless fit, crafted with care in Brooklyn.
