Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of a 6 x 4 mm oval diamond, its soft glow tracing the contours of your hand. This halo engagement ring, set in cool platinum, frames the center stone with a delicate circle of pavé diamonds, enhancing its gentle brilliance without overwhelming its refined silhouette.

Each ring is meticulously crafted in our Williamsburg studio, where the platinum band is hand-polished to a satin finish that feels smooth and substantial against the skin. The low-profile setting ensures comfort for daily wear, while the halo adds subtle sparkle that complements stacking with other bands or a wedding ring.

Our diamonds are lab-grown, offering a clarity and fire that reflect a commitment to sustainability and ethical sourcing without compromise. The oval shape’s elongated form visually lengthens the finger, lending an elegant, modern grace to the design.

Designed for those who appreciate artisan detail and understated luxury, this ring balances presence with wearability—glove-friendly and suited to a variety of lifestyles. Resizing is available to ensure a precise fit, crafted with the same care as the original design.
