Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that seems to stretch the hand with quiet elegance. This halo setting cradles a 12 x 6 mm lab-grown marquise diamond in polished platinum, its low-profile design ensuring the ring sits close to the finger for everyday ease.

Crafted in our Williamsburg studio, the platinum band is meticulously finished to a smooth comfort fit, balancing durability with refined wearability. The halo of pavé-set stones enhances the center’s brilliance without adding bulk, making it glove-friendly and ideal for stacking alongside wedding bands.

Each diamond is ethically sourced through lab-grown technology, reducing environmental impact while delivering exceptional clarity and sparkle. The marquise shape’s tapered points offer a distinctive architectural grace, perfect for those who appreciate subtle drama in their jewelry.

Designed for daily life, this ring suits slender to medium finger sizes, its streamlined profile minimizing snagging and maximizing comfort. Resizing is available to ensure a precise fit, with care instructions provided to maintain the platinum’s polished sheen.
