Lab-Grown Diamond Engagement Ring

Sunlight catches the 8.2 mm round lab-grown diamond at the heart of this platinum engagement ring, scattering light with a quiet brilliance that invites closer admiration. The low-profile setting secures the stone with subtle accent details, crafted to sit comfortably beneath a sleeve or glove without catching.

Each ring is meticulously finished in our Williamsburg studio, where platinum’s cool weight is hand-polished to a satin sheen that balances durability with refined elegance. The setting’s precision ensures the diamond remains the focal point while the band’s smooth interior offers a comfort fit designed for everyday wear.

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

Ideal for those who appreciate a modern yet understated silhouette, this ring complements slender or average finger shapes and layers effortlessly with other bands. Its low profile and secure setting make it a practical choice for active lifestyles.

Should you need a custom adjustment, resizing is available to ensure a perfect fit without altering the ring’s balance or comfort.
