Lab-Grown Diamond Engagement Ring

Under the soft glow of a Williamsburg evening, the square lab-grown diamond catches the light with quiet intensity, framed by a delicate halo that whispers of enduring devotion. This platinum engagement ring balances architectural clarity with a gentle embrace, its 7 x 7 mm square center stone set low for everyday grace.

Crafted with precision, the halo setting enhances the diamond’s crisp edges while the polished platinum band offers a smooth, comfort fit that settles naturally against the skin. Each facet is inspected in-studio to ensure the interplay of light remains vivid without overwhelming the hand.

Ethically sourced, the lab-grown diamond reflects a commitment to sustainability without sacrificing brilliance or character.

Designed for those who appreciate modern geometry softened by romantic detail, this ring pairs effortlessly with stacking bands and slips comfortably beneath gloves or sleeves. Its low-profile setting suits active lifestyles while maintaining an elegant silhouette.

Should you need a custom adjustment, resizing is handled delicately in-house to preserve the ring’s refined proportions.
