Lab-Grown Diamond Engagement Ring

Soft light catches the gentle curves of a 7 x 7 mm cushion diamond, its rounded corners and subtle facets inviting a quiet intimacy. This three-stone semi-set in cool platinum offers a balanced stage for your chosen center stone, framed by two delicate side settings crafted with precision.

Each band is hand-finished in our Williamsburg studio, where the platinum is polished to a satiny sheen that feels smooth against the skin. The low-profile mounting ensures comfort for daily wear, while the three-stone design adds a layered depth without excess height, making it glove-friendly and ideal for stacking.

Our diamonds are lab-grown, reflecting a commitment to sustainable sourcing and ethical clarity without compromise. This ring’s structure suits those who appreciate a blend of classic form and modern craftsmanship, especially hands that favor a substantial yet refined silhouette.

Should you wish to adjust the fit, resizing is available with care to maintain the integrity of the setting. Lead times are tailored to your custom design process, ensuring a thoughtful creation rather than a rushed assembly.
