Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that seems to stretch beyond the hand. This semi-set halo engagement ring foundation in warm 10K yellow gold invites your choice of a 10 x 5 mm center stone, framing it with a delicate halo that amplifies light and lends a whisper of vintage romance.

Crafted in Williamsburg, the band’s gentle curve and low-profile setting ensure comfort for daily wear, while the polished finish reflects subtle warmth against the skin. The halo setting is designed to enhance the marquise’s tapered drama without overwhelming its architectural grace.

Each ring is made with lab-grown diamonds, chosen for their clarity and ethical origins, reflecting a commitment to sustainability without compromise on brilliance.

This design suits those who appreciate a balance of bold shape and refined detail—its slender form elongates the finger, while the halo adds a soft glow that pairs beautifully with stackable bands or a solitaire style.

Resizing is available to ensure a perfect fit, and the semi-set nature allows you to select a center stone that resonates personally, with expert guidance from our Brooklyn studio.
