Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a marquise diamond catching light with every turn of the hand—its pointed ends lending a graceful, tapered drama. This semi-set halo engagement ring in 10K rose gold frames a 9 x 4.5 mm marquise center, designed to amplify brilliance while maintaining a low profile that slips comfortably beneath daily gloves or sleeves.

Crafted in Williamsburg, the band’s gentle curve and secure halo setting balance elegance with durability, finished to a smooth comfort fit that feels natural for everyday wear. The rose gold’s warm glow complements the diamond’s fiery facets, polished meticulously to highlight each reflective angle without excess height.

Our commitment to ethical jewelry is reflected in the lab-grown diamond’s clarity and sustainability, offering a conscious choice without compromise on sparkle or character.

Ideal for those who appreciate refined geometry and a ring that layers effortlessly with wedding bands or stackable styles, this design suits slender to medium finger shapes, enhancing length and grace.

Should you need resizing, our Brooklyn studio handles adjustments with care, ensuring the ring maintains its structural integrity and finish.
