Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 6 x 6 mm cushion diamond, its gentle glow framed by two smaller stones that balance modern clarity with quiet confidence. This three-stone semi-set in cool platinum offers a structured silhouette, where clean lines meet a subtle architectural grace.

Each band is crafted in our Williamsburg studio, polished to a satin finish that feels smooth against the skin and designed with a low-profile setting to sit comfortably beneath daily wear. The platinum’s natural strength ensures durability while maintaining a refined, lightweight presence on the finger.

Our diamonds are lab-grown, chosen for their exceptional clarity and ethical origin, reflecting a commitment to sustainability without compromise. This ring’s shape and size suit those who appreciate a blend of classic warmth and contemporary minimalism, ideal for stacking or wearing solo with ease.

Should you wish to adjust the fit, resizing is available through our in-studio service, ensuring your ring remains as comfortable as it is striking. Lead times are typically four to six weeks, allowing for meticulous craftsmanship tailored to your vision.
