Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a marquise diamond catching the light as you move through a sunlit Brooklyn street. This semi-set engagement ring frame in warm 10K rose gold awaits your choice of a 12 x 6 mm marquise center, its pointed silhouette lending a graceful drama without overwhelming the hand.

Crafted with a low-profile setting, the band sits close to the finger for everyday comfort and ease beneath gloves or layered with other rings. The rose gold’s gentle blush complements the marquise’s sharp geometry, while delicate accent stones add a quiet shimmer, enhancing the center without distraction. Each piece is meticulously finished by hand in our Williamsburg studio, ensuring smooth edges and a secure fit.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint.

Designed for those who appreciate refined details and a sleek silhouette, this mounting suits slender to medium finger sizes and pairs effortlessly with stackable bands. Its comfort fit and modest height make it an ideal choice for daily wear.

Should you need resizing or prefer a custom accent arrangement, our Brooklyn studio offers personalized consultations to tailor your ring precisely.
