Lab-Grown Diamond Engagement Ring

Light catches the sharp edges of a 5 x 5 mm square lab-grown diamond, its precise geometry framed by a delicate halo that amplifies every facet’s fire. This platinum engagement ring balances architectural clarity with subtlety, designed to sit close to the finger for everyday grace.

Crafted in Williamsburg, Brooklyn, the ring features a low-profile halo setting that protects the diamond while allowing maximum brilliance. The platinum band is polished to a smooth comfort fit, ensuring it wears effortlessly alongside wedding bands or stackable rings.

Each lab-grown diamond is selected for clarity and ethical origin, reflecting a commitment to sustainability without compromising on sparkle. The cool white metal complements the diamond’s crisp lines, creating a modern silhouette that suits hands seeking refined geometry.

Ideal for those who appreciate clean angles and a secure setting, this ring’s design minimizes snagging and fits comfortably under gloves or daily wear. Resizing is available to ensure a precise fit, crafted with care in our Brooklyn studio.
