Lab-Grown Diamond Engagement Ring

Under the soft glow of Williamsburg’s evening light, a square lab-grown diamond catches the eye with quiet intensity, framed by a delicate halo that amplifies its architectural clarity. This platinum engagement ring balances bold geometry with a whisper of romance, its cool metal band polished to a satin finish that feels smooth and substantial against the skin.

Crafted with precision, the halo setting elevates the 10 x 10 mm square diamond, allowing light to dance across its facets while maintaining a low profile for everyday wear. The comfort-fit band curves gently, designed to sit seamlessly alongside other rings or stand alone with confident grace.

Each diamond is ethically sourced from a lab-grown origin, reflecting a commitment to sustainability without compromising brilliance or clarity. The platinum setting is hand-finished in our Brooklyn studio, ensuring every detail meets exacting standards.

This ring suits those who appreciate modern geometry paired with subtle elegance—its square shape lends a structured silhouette that elongates the finger, while the halo adds a soft glow. Its balanced proportions make it ideal for stacking or wearing solo, and the low-profile setting slips easily under gloves or sleeves.

Should you need a custom fit, resizing is available with care to preserve the ring’s integrity and finish. Typical lead times reflect our dedication to handcrafted quality.
