Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise diamond, measuring 9 by 4.5 millimeters, draws the eye with its tapered points and graceful presence. This semi-set halo engagement ring foundation in 18K yellow gold offers a subtle contrast to the bright white gold halo setting, designed to amplify brilliance without adding bulk.

Crafted for everyday wear, the low-profile mounting keeps the ring close to the finger, minimizing snagging while maintaining a refined balance between sparkle and comfort. Each band is hand-finished in our Williamsburg studio, ensuring smooth edges and a comfort fit that adapts seamlessly to daily life.

Our commitment to ethical jewelry is reflected in the use of lab-grown diamonds, which provide exceptional clarity and sustainability without compromise.

The slender shape of the marquise suits those who appreciate a ring that elongates the hand and pairs effortlessly with stacking bands or wedding rings. Its semi-set state invites you to select a center stone that matches your vision, while the halo setting enhances size and light play.

Should resizing be needed, our Brooklyn studio offers precise adjustments to maintain the ring’s integrity and comfort.
