Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 12 mm round diamond, poised to become the heart of a three-stone engagement ring. This semi-set design invites you to select a center stone that will harmonize with the warm glow of 10K rose gold, hand-shaped in our Williamsburg studio.

The band’s subtle sweep is crafted for everyday wear, its smooth finish and modest profile ensuring comfort beneath a sleeve or glove. Each prong is meticulously formed to cradle your chosen diamond securely while allowing light to dance freely, enhancing brilliance without excess height.

Our commitment to sustainability is reflected in the lab-grown diamond option, offering clarity and sparkle with a lighter environmental footprint. This ring’s design suits those who appreciate artisan detail and a balanced silhouette, ideal for stacking or wearing solo with quiet confidence.

Should you need adjustments, resizing is handled in-house with care to preserve the band’s integrity and finish. Typical lead times accommodate thoughtful customization without rush.
