Lab-Grown Diamond Engagement Ring

Sunlight catches the subtle dance of five stones aligned with quiet precision, each poised to amplify the brilliance of a 7.4 mm round center diamond. This semi-set platinum band offers a modern-minimal silhouette, where clean lines and structural clarity frame the centerpiece without distraction.

Crafted in Williamsburg, the ring’s low-profile setting ensures a comfortable fit beneath daily wear, while the cool weight of platinum lends a reassuring solidity. Each prong is meticulously finished to cradle stones securely, enhancing light reflection and maintaining a sleek profile that slips easily under gloves or alongside stackable bands.

Our lab-grown diamonds bring a clarity and sparkle indistinguishable from mined stones, created with a commitment to sustainability and ethical sourcing that quietly honors your values.

Designed for those who appreciate refined geometry and confident understatement, this five-stone semi-set invites you to select a center diamond that resonates with your personal story. The round shape’s classic brilliance elongates the finger subtly, balancing presence with everyday grace.

Should you need resizing or custom adjustments, our Brooklyn studio offers attentive care to ensure your ring fits as naturally as it shines.
