Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp, architectural facets of an 8 x 8 mm Asscher diamond, its step-cut planes reflecting a quiet geometry that feels both modern and deliberate. This semi-set three-stone ring foundation in cool platinum offers a sculptural frame, crafted with precision in our Williamsburg studio where each edge is hand-finished to a smooth, low-profile silhouette.

The platinum band is polished to a satiny sheen, designed for daily wear with a comfort fit that rests lightly on the finger. Its three-stone setting balances presence with subtlety, allowing your chosen center diamond to command attention without overwhelming the hand.

Each lab-grown diamond chosen for this setting carries the clarity and brilliance of sustainable creation, reflecting a commitment to ethical jewelry without compromise.

Ideal for those who appreciate architectural elegance and a ring that layers effortlessly with other bands, this setting suits a range of hand shapes and sizes, especially those who favor a refined, glove-friendly profile.

Resizing is available to ensure a precise fit, with careful attention to maintaining the integrity of the platinum’s finish.
