Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to cradle the hand in quiet elegance. This semi-set halo ring in 10K white gold frames a 9 x 4.5 mm marquise center with a whisper of pavé brilliance, enhancing the stone’s graceful drama without overwhelming its refined shape.

Crafted in our Williamsburg studio, the band’s smooth comfort fit and low-profile setting ensure it wears effortlessly every day, slipping easily beneath gloves or alongside other stackable bands. Each detail is hand-finished and inspected to balance sparkle with practicality, honoring the intimate moments it will witness.

Our commitment to ethical jewelry shines through the use of a lab-grown diamond, offering clarity and fire with a smaller environmental footprint. This choice reflects a modern romance rooted in responsibility.

Ideal for those who appreciate architectural beauty with a poetic edge, the marquise shape elongates the finger, while the halo setting adds a subtle glow that feels both personal and luminous. The semi-set design invites you to select a center stone that resonates with your story.
