Lab-Grown Diamond Engagement Ring

Imagine the quiet moment when a softly glowing cushion diamond begins its journey, waiting to be chosen and set into a ring that reflects your story. This semi-set platinum band offers a sleek, modern-minimal foundation designed to showcase a 5 x 5 mm cushion-cut center stone—its gently rounded corners and subtle facets creating a luminous, vintage-inspired glow with contemporary clarity.

Crafted in platinum for enduring strength and a cool, refined finish, the band features delicate accent settings that frame the center stone without overwhelming it. The low-profile design ensures comfortable daily wear, while the smooth interior promises a gentle fit against the skin. Each piece is meticulously finished and inspected in our Williamsburg studio, where precision meets quiet confidence.

Our commitment to sustainability is reflected in the exclusive use of lab-grown diamonds, offering exceptional clarity and brilliance with a lighter environmental footprint.

This ring suits those who appreciate structured elegance and understated sparkle, ideal for stacking with other bands or worn solo as a statement of refined taste. Its balanced proportions complement a variety of hand shapes, while the semi-set style invites you to select a center stone that resonates personally.
