Lab-Grown Diamond Engagement Ring

Imagine the quiet moment when light catches the soft, rounded corners of a 5 x 5 mm cushion-cut diamond, its gentle glow framed by two smaller stones that echo its modern-minimal geometry. This three-stone semi-set engagement ring in platinum offers a refined structure, balancing clarity with confident simplicity.

Crafted in Williamsburg, the platinum band is polished to a satin finish that feels substantial yet smooth against the skin. The low-profile setting ensures daily wearability without catching, while the three-stone arrangement adds depth and dimension without excess.

Each diamond is lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

Designed for those who appreciate architectural elegance with a subtle edge, this ring suits hands that favor clean lines and a contemporary silhouette. Its comfort fit and modest height make it ideal for stacking or wearing solo, blending seamlessly with a variety of styles.

Should you wish to adjust the fit, resizing is handled delicately in-studio to maintain the integrity of the platinum band and setting.
