Lab-Grown Diamond Engagement Ring

Sunlight catches the softly rounded corners of a 10 x 10 mm cushion diamond, its gentle glow framed by two smaller stones that balance presence with quiet elegance. This three-stone semi-set invites you to select a center diamond that will become the heart of a bespoke platinum band, shaped and polished in our Williamsburg studio.

The band’s low-profile setting ensures the ring sits comfortably for daily wear, its smooth platinum surface finished to a satiny sheen that resists scratches while feeling substantial on the finger. Each prong is meticulously hand-forged to cradle your chosen diamond securely, reflecting the artisan workshop’s commitment to precision and durability.

Crafted with lab-grown diamonds, this design honors an ethical approach to fine jewelry, reducing environmental impact without compromising on brilliance or clarity.

Ideal for those who appreciate a balanced silhouette, the cushion shape’s soft edges complement a variety of hand sizes and shapes, while the three-stone layout offers versatility for stacking or wearing solo. Its modest profile fits comfortably under gloves or sleeves, making it a practical choice for everyday elegance.

Should you need resizing, our in-studio experts ensure a seamless adjustment without disrupting the ring’s integrity or finish.
