Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a poised brilliance that draws the eye along the finger. This semi-set halo engagement ring foundation in cool platinum offers a refined stage for a 9 x 4.5 mm marquise center stone, framed by a delicate halo that enhances its architectural shape without overwhelming.

Crafted in Williamsburg, Brooklyn, the platinum band is polished to a soft sheen, designed for everyday wear with a low-profile setting that slips comfortably beneath gloves and stacks effortlessly with other bands. The halo setting is meticulously finished to balance sparkle and structure, ensuring the ring feels as thoughtful as it looks.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, combining sustainability with exceptional clarity and brilliance. This ring suits those who appreciate modern minimalism with a confident edge—ideal for hands that favor elongated shapes and a sleek silhouette.
