Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances with every movement. This semi-set halo engagement ring in 18K rose gold frames a 6 x 3 mm marquise center with a gentle embrace of smaller stones, enhancing its graceful taper and vintage allure.

Crafted in Williamsburg, Brooklyn, the warm rose gold band is polished to a soft glow, designed with a low-profile setting that rests close to the finger for everyday comfort. The halo setting adds subtle brilliance without overwhelming the refined shape, making it ideal for stacking or wearing solo.

Each lab-grown diamond is ethically sourced, offering clarity and sparkle with a mindful footprint. The marquise cut’s elongated form visually lengthens the hand, suited for those who appreciate a blend of architectural elegance and romantic detail.

Resizing is available to ensure a perfect fit, and the semi-set design invites you to select a center stone that reflects your personal story. Whether you visit our Williamsburg studio or explore the design process online, this ring is a quiet celebration of craftsmanship and intention.
