Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc across the finger. This semi-set halo ring in warm 14K rose gold frames a 7 x 3.5 mm center stone, inviting you to choose a lab-grown gem that balances drama with refined elegance.

Crafted with a low-profile halo setting, the band’s gentle curve ensures comfort for daily wear while the rose gold’s subtle blush complements the diamond’s fiery sparkle. Each piece is meticulously finished in our Williamsburg studio, where hand polishing and precise prong work guarantee a secure yet graceful mount.

Our commitment to ethical jewelry shines through the lab-grown diamond’s clarity and sustainability, offering brilliance without compromise. The marquise shape’s tapered form visually elongates the hand, making it a striking choice for those who appreciate a blend of vintage allure and modern design.

Designed to pair effortlessly with stacking bands or stand alone as a statement, this ring suits a wearer who values both artistry and practicality. Should resizing be needed, our in-house experts ensure a seamless adjustment without disrupting the ring’s balance.
