Lab-Grown Diamond Engagement Ring

Soft light catches the gentle curves of a 5 x 5 mm cushion diamond, its rounded corners and subtle facets inviting a quiet intimacy. This three-stone semi-set in cool platinum awaits your choice of center stone, framed by two delicate side settings that balance presence with grace.

Each band is hand-shaped in our Williamsburg studio, polished to a satiny finish that feels smooth against the skin. The low-profile setting ensures the ring sits comfortably beneath gloves or daily wear, while the three-stone design offers a harmonious play of light and shadow.

Crafted exclusively with lab-grown diamonds, this piece reflects a commitment to ethical jewelry—minimizing environmental impact without sacrificing brilliance.

Its refined silhouette suits those who appreciate subtle drama and versatility, pairing effortlessly with stackable bands or worn solo as a statement of enduring style.

Should you need resizing, our in-studio artisans handle adjustments with care to maintain the ring’s seamless form.
