Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of a 7 x 5 mm oval diamond, its halo of delicate platinum prongs amplifying every flicker of fire. This engagement ring balances modern minimalism with architectural clarity, the halo setting framing the stone like a quiet spotlight.

Crafted in solid platinum, the band offers a cool, substantial feel that molds comfortably to the finger. The low-profile halo setting ensures daily wearability without catching, while the polished finish reflects Brooklyn’s understated edge. Each ring is meticulously inspected in our Williamsburg studio, where precision meets thoughtful design.

Our diamonds are lab-grown, offering a transparent origin and a smaller environmental footprint without compromising brilliance or clarity.

Ideal for those who appreciate refined structure and confident simplicity, this ring pairs effortlessly with stackable bands or stands alone as a statement of subtle elegance. Its shape elongates the finger, lending a graceful silhouette that suits a variety of hand sizes.
