Under the soft glow of a Brooklyn evening, the 6 x 6 mm cushion-cut diamond catches light with a gentle, vintage-inspired shimmer—its rounded corners and subtle facets inviting quiet admiration. This platinum engagement ring is crafted with a low-profile setting that nestles close to the finger, designed for everyday wear without sacrificing elegance.

Each ring is meticulously finished in our Williamsburg studio, where the platinum band is hand-polished to a satiny smoothness that feels weightless yet substantial. The accent stones frame the center diamond with precision, enhancing its warm glow while maintaining a streamlined silhouette that slips easily beneath gloves or sleeves.

Our diamonds are lab-grown, offering clarity and brilliance with a significantly reduced environmental footprint, reflecting a commitment to ethical jewelry without compromise.

The comfort-fit band suits those who value subtle sophistication and practicality, ideal for stacking alongside wedding bands or worn solo as a statement of refined taste. Its balanced proportions complement a range of hand shapes, especially those seeking a ring that harmonizes with daily life.

Should you need resizing, our in-house artisans ensure a seamless adjustment without disrupting the ring’s integrity or finish.
