Lab-Grown Diamond Engagement Ring

Sunlight catches the softly rounded corners of a 12 x 12 mm cushion-cut diamond, its gentle facets unfolding like a quiet glow across the hand. This platinum engagement ring is crafted with a low-profile setting that nestles close to the finger, designed for everyday grace without catching or shifting.

The band’s polished finish and subtle accent stones frame the center with refined restraint, while the comfort fit ensures a seamless feel beneath gloves or alongside stackable rings. Each piece is meticulously inspected in our Williamsburg studio, where precision meets a modern sensibility.

Our diamonds are lab-grown, offering clarity and brilliance with a significantly reduced environmental footprint.

Ideal for those who appreciate a balance of presence and practicality, this ring complements a variety of hand shapes and sizes, especially suited for wearers seeking a statement that remains effortlessly wearable.

Resizing is available to ensure a perfect fit, with care instructions provided to maintain the platinum’s enduring sheen.
