Morning light catches the sharp edges of an 8 x 8 mm square diamond, its facets unfolding like a quiet architectural statement. This platinum engagement ring is crafted with a low-profile setting that keeps the stone close to the finger, balancing presence with everyday comfort.

Each accent stone is precisely set to enhance the geometric clarity of the center diamond, while the platinum band is hand-finished for a smooth, comfort fit that resists daily wear. The ring’s streamlined silhouette slips easily beneath gloves or alongside other bands, making it a practical choice for a modern lifestyle.

Our lab-grown diamonds offer the same optical brilliance as mined stones with a significantly reduced environmental footprint, reflecting a commitment to ethical jewelry without compromise.

Designed for those who appreciate clean lines and confident structure, this ring suits hands that favor architectural elegance and a subtle yet unmistakable statement. Its balanced proportions and secure setting ensure it can be worn every day without hesitation.

Should you need a custom adjustment, resizing is handled with care in our Williamsburg studio, ensuring the ring fits perfectly over time.
