Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow across the hand. This semi-set halo engagement ring invites you to choose a 6 x 3.5 mm center stone, its pointed ends drawing the eye along a graceful line.

Crafted from 18K white gold, the band is meticulously shaped for a smooth, comfortable fit that sits low against the finger. The halo setting, composed of finely milled pavé diamonds, amplifies the center’s brilliance while maintaining a refined profile ideal for everyday wear. Each element is hand-finished in our Williamsburg studio, where artisan techniques meet modern precision.

Choosing a lab-grown diamond for this ring supports a more sustainable approach to fine jewelry, reducing environmental impact without compromising clarity or fire.

The slender marquise shape naturally elongates the finger, making this design especially flattering for those who appreciate a sleek, architectural aesthetic. Its low-profile setting pairs well with stacking bands or a wedding ring, and the comfort fit ensures ease beneath gloves or daily tasks.

Should you need resizing, our in-house jewelers provide careful adjustments to maintain the ring’s integrity and balance.
