Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it casts a delicate, shimmering shadow that seems to dance with every movement. This semi-set halo engagement ring foundation in warm 18K rose gold frames a 6 x 3 mm marquise center with a subtle embrace, designed to amplify the stone’s tapered drama without overwhelming the hand.

Crafted in our Williamsburg studio, the band’s gentle curve and low-profile halo setting ensure a comfortable fit for daily wear, while the polished finish reflects soft glimmers of rose-hued light. The semi-set design invites you to select a lab-grown marquise diamond that speaks to your unique story, promising precision in cut and clarity.

Our commitment to ethical jewelry shines through the use of sustainably sourced lab-grown diamonds, offering brilliance without compromise. The slender rose gold band suits those who appreciate a romantic yet modern aesthetic, pairing effortlessly with stacking rings or worn solo for understated elegance.
