Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a square lab-grown diamond, its precise facets reflecting a quiet geometry that anchors the gaze. This engagement ring, set in polished platinum, balances architectural clarity with a low-profile silhouette designed for everyday grace.

The 5 x 5 mm square diamond sits securely within a refined platinum setting, accented subtly to enhance its crisp lines without adding bulk. The band’s comfort fit and streamlined profile ensure it rests naturally on the finger, ideal for those who favor understated strength over flash.

Crafted in our Williamsburg studio, the ring embodies a commitment to ethical sourcing through lab-grown clarity, reducing environmental impact while maintaining exceptional brilliance.

Its clean shape and moderate size suit hands seeking modern geometry with practical wearability—stackable with other bands or worn solo, it slips easily beneath gloves and sleeves.

Should you need a custom fit, resizing is handled delicately in-house to preserve the ring’s integrity and finish.
