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 foundation in warm 14K rose gold frames a 10 x 5 mm marquise center with a delicate halo, designed to amplify its tapered drama without overwhelming the hand.

Crafted for everyday wear, the low-profile setting keeps the silhouette sleek and close to the finger, while the smooth band ensures comfort throughout your day. Each piece is meticulously finished in our Williamsburg studio, where precision meets quiet elegance in every curve and prong.

Our lab-grown diamonds offer a clarity and brilliance that honors both beauty and sustainability, reflecting a commitment to ethical jewelry without compromise.

This ring suits those who appreciate refined geometry and a subtle statement—its shape naturally elongates the finger, pairing effortlessly with stackable bands or worn solo. The semi-set design invites you to select a marquise stone that resonates with your personal story.

Should you need resizing or have questions about care, our team provides thoughtful guidance to ensure your ring fits seamlessly into your life.
