Lab-Grown Diamond Engagement Ring

Sunlight catches the 5.8 mm round diamond, scattering light with a quiet brilliance that feels both intimate and enduring. This platinum engagement ring is crafted with a low-profile setting that nestles close to the finger, designed for everyday wear without catching or shifting.

The band’s smooth finish and subtle accent stones frame the center diamond with precision, highlighting its classic round cut—a shape celebrated for its balanced fire and sparkle. Each ring is meticulously finished in our Williamsburg studio, where comfort fit shaping ensures it slides on effortlessly and rests securely.

Our commitment to ethical jewelry is reflected in the lab-grown diamond’s clarity and origin, offering a sustainable alternative without compromise on beauty or durability.

Ideal for those who appreciate refined craftsmanship and a ring that complements a busy lifestyle, this design layers well with wedding bands or stands confidently alone. Its modest profile makes it glove-friendly and unobtrusive during daily tasks.

Should you need resizing, we handle adjustments with care to maintain the ring’s integrity and finish. Typical lead times reflect our hands-on approach to custom quality.
