Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of an 8 x 4 mm marquise diamond, its tapered points drawing the eye along a delicate arc. This three-stone semi-set engagement ring in 14K rose gold offers a handcrafted foundation ready to cradle your chosen center stone with artisan precision.

Each band is shaped and finished in our Williamsburg studio, where the warm blush of rose gold is polished to a soft glow that complements the marquise’s dramatic profile. The setting’s low profile and secure prongs ensure everyday comfort without sacrificing the diamond’s striking presence.

Crafted with lab-grown diamonds, this ring reflects a commitment to ethical jewelry—minimizing environmental impact while maximizing brilliance and clarity.

Designed for those who appreciate refined geometry and subtle romance, the three-stone layout balances the marquise’s tapered drama with harmonious side stones. Its slender band fits comfortably beneath gloves and stacks effortlessly with wedding bands or accent rings.

Should you need resizing, our in-studio experts handle adjustments with care to maintain the ring’s integrity and finish.
