Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 7x7 mm cushion diamond, its gentle glow framed by a halo that amplifies every flicker of light. This semi-set engagement ring invites you to select a center stone that balances vintage warmth with modern clarity.

Crafted from 10K white gold, the band is meticulously shaped for a comfortable fit, its low-profile halo setting designed to sit close to the finger without sacrificing sparkle. Each curve and facet is refined in our Williamsburg studio, where artisan hands polish and inspect every detail to ensure seamless wearability and enduring beauty.

Choosing a lab-grown diamond here reflects a commitment to ethical jewelry—minimizing environmental impact while offering exceptional clarity and brilliance.

The ring’s silhouette suits those who appreciate subtle drama: the cushion cut’s soft edges complement a variety of hand shapes, while the halo setting adds dimension without bulk, making it ideal for stacking or daily wear. Its comfort fit and modest height also make it glove-friendly for seasonal layering.

Should you wish to adjust sizing, our in-studio experts provide precise resizing to maintain the ring’s integrity and comfort.
