Lab-Grown Diamond Engagement Ring

When light catches the edges of a square diamond, it fractures into a quiet dance of sharp brilliance and subtle fire. This five-stone semi-set engagement ring frames a 4.5 x 4.5 mm square center stone, its geometric clarity balanced by the gentle shimmer of four smaller companions.

Crafted in 10K white gold, the band offers a cool, smooth embrace with a low-profile setting that rests comfortably for everyday wear. Each prong is meticulously shaped and polished in our Williamsburg studio, ensuring the stones sit securely while allowing maximum light to animate their facets.

Our commitment to sustainability is reflected in the lab-grown clarity of the diamonds—ethical jewelry that honors both beauty and conscience without compromise.

The ring’s refined silhouette suits hands that appreciate modern geometry softened by romantic detail. Its modest height and slender band make it ideal for stacking or wearing solo, while the square shape lends a contemporary edge that elongates the finger.

Should you need a custom fit, resizing is handled with care by our Brooklyn artisans to maintain the integrity of the design.
