Lab-Grown Diamond Engagement Ring

Under the soft glow of Williamsburg’s evening light, this platinum engagement ring captures a quiet moment of devotion. The square lab-grown diamond, precisely measured at 4.5 by 4.5 millimeters, anchors a delicate halo that amplifies its architectural clarity with a gentle shimmer.

Crafted in our Brooklyn studio, the ring’s low-profile setting ensures it sits close to the finger, balancing presence with everyday comfort. The platinum band is polished to a satiny finish, its cool weight grounding the design while the halo’s pavé diamonds catch light from every angle. Each piece undergoes meticulous hand inspection to meet exacting standards.

Choosing a lab-grown diamond reflects a commitment to ethical jewelry, reducing environmental impact without compromising brilliance or clarity.

This ring suits those who appreciate modern geometry softened by romantic detail—its square shape offers a confident silhouette that elongates the finger subtly. The halo setting adds dimension without bulk, making it ideal for stacking or wearing alone with ease.

Should you need resizing, our studio offers precise adjustments to ensure a perfect fit without altering the ring’s balance or comfort.
