Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances along the warm blush of 18K rose gold. This semi-set halo ring invites you to choose a center stone that echoes your unique story, framed by a circle of meticulously hand-set pavé diamonds that amplify its graceful taper.

Crafted in our Williamsburg studio, the band is shaped for comfort with a subtle curve that rests lightly against the finger, designed to wear seamlessly every day. The halo setting balances brilliance with a low profile, ensuring the ring slips easily beneath gloves or alongside stackable bands without catching.

Each piece begins with ethically sourced lab-grown diamonds, chosen for their clarity and sustainability, reflecting a commitment to responsible luxury. The rose gold is hand-finished to a soft satin sheen, highlighting the artisan’s touch in every contour and prong.

Ideal for those drawn to vintage-inspired forms with a modern sensibility, this marquise halo ring flatters slender fingers and elongates the hand’s natural lines. The semi-set design offers the freedom to select a center diamond that fits your vision and budget.
