Lab-Grown Diamond Engagement Ring

Imagine the quiet sparkle of a square lab-grown diamond catching the soft light of a Williamsburg afternoon, framed by four delicate side stones that whisper of shared moments yet to come. This semi-set platinum band awaits your choice of a 5 x 5 mm square center stone, its clean lines offering a modern geometry that balances strength with refined elegance.

Crafted in platinum for enduring wear, the setting features a low-profile design that sits close to the finger, ensuring comfort throughout daily life. Each prong is meticulously shaped and polished in our Brooklyn studio, where every detail is inspected to meet exacting standards without excess.

Our diamonds are lab-grown with clarity and sustainability at their core, reflecting a commitment to ethical jewelry that honors both beauty and responsibility.

The five-stone arrangement suits those who appreciate subtle sparkle and a balanced silhouette, ideal for stacking or wearing solo with a glove-friendly fit. The square shape’s architectural presence complements a variety of hand sizes, lending a quiet confidence to the wearer.

Should you wish to adjust the band size, resizing is available with care to preserve the integrity of the setting. Typical lead times align with our bespoke process, ensuring your ring is crafted thoughtfully.
