Lab-Grown Diamond Engagement Ring

Sunlight catches the slender silhouette of a marquise diamond, its tapered points tracing a delicate arc that seems to elongate the fingers with quiet grace. This semi-set halo engagement ring in 14K rose gold frames a 6 x 3.5 mm marquise center stone, inviting you to select a lab-grown diamond that balances brilliance with a refined, vintage-inspired allure.

The rose gold band is hand-polished to a soft glow, its warm hue complementing the halo’s intricate pavé setting that amplifies light without overwhelming the stone’s elegant shape. Designed with a low-profile setting, this ring offers comfort for daily wear while maintaining a striking presence.

Crafted in Williamsburg, Brooklyn, the ring reflects a commitment to sustainable luxury—each lab-grown diamond embodies clarity and ethical sourcing without compromise.

Its slender band and subtle halo make this piece ideal for those who appreciate romantic detail with modern restraint, fitting seamlessly alongside wedding bands or stackable favorites. The low profile ensures ease of wear, even for those with active lifestyles or glove preferences.

Should you wish to adjust sizing, our in-studio experts provide precise, careful resizing to maintain the ring’s integrity and comfort.
