Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it carves a striking, confident line across the hand—an emblem of modern-minimal elegance. This semi-set platinum engagement ring invites you to select a 10 x 5 mm marquise center stone, framed by a halo that amplifies its architectural brilliance with subtle sparkle.

Crafted in Williamsburg, the platinum band offers a cool, substantial feel with a low-profile setting designed for everyday grace and comfort. The halo setting is meticulously finished to balance light reflection and wearability, ensuring the ring sits close to the finger without sacrificing presence.

Each lab-grown diamond chosen for this design reflects a commitment to ethical sourcing and sustainability, embodying clarity both in gem and conscience.

Its sleek silhouette suits hands that appreciate refined geometry and those who favor stackable bands or a glove-friendly fit. The marquise shape’s tapered points elongate the finger, making it a compelling choice for those drawn to confident, structured forms.

Should you need resizing or prefer a custom stone cut, our Brooklyn studio offers tailored adjustments with attentive care and transparent timelines.
