Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise diamond captures light with a subtle, tapered brilliance that draws the eye along the finger’s natural line. This semi-set engagement ring in 18K yellow gold offers a refined foundation, ready to showcase a 5 x 3 mm marquise center stone with delicate accent details that enhance its graceful profile.

Crafted with a low-profile setting, the band sits close to the hand, minimizing catch and maximizing comfort for daily wear. The warm glow of 18K yellow gold is hand-finished in Williamsburg, ensuring a smooth, polished surface that complements the diamond’s sharp geometry without overwhelming it.

Each ring is designed around a lab-grown diamond, chosen for its clarity and ethical origin, reflecting a commitment to sustainability without compromise on brilliance or beauty.

Ideal for those who appreciate a sleek, architectural shape with a subtle vintage nod, this mounting suits slender fingers and pairs well with stackable bands or a simple wedding ring. Its low profile makes it glove-friendly and unobtrusive for everyday life.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure a perfect fit without disrupting the ring’s balance or silhouette.
