Lab-Grown Diamond Engagement Ring

Under the soft glow of a Williamsburg evening, the 9.4 mm round lab-grown diamond captures light like a quiet promise, its halo setting amplifying every flicker with delicate precision. The platinum band, cool and substantial, embraces the stone with a low-profile silhouette that rests comfortably against the skin, designed for daily wear without distraction.

Each ring is meticulously crafted in our Brooklyn studio, where the halo setting is hand-finished to ensure the diamonds encircling the center stone align perfectly, enhancing brilliance while maintaining a refined elegance. The comfort-fit band curves gently, allowing for effortless stacking or solo statement.

Our diamonds are sustainably grown, offering clarity and fire without the environmental cost of mining, reflecting a commitment to ethical jewelry that honors both beauty and conscience.

This engagement ring suits those who appreciate a balance of romantic detail and modern restraint—its halo adds a whisper of vintage allure while the platinum’s cool sheen keeps it grounded in contemporary craft. The low profile makes it glove-friendly and ideal for an active lifestyle.

Should you need a custom fit, resizing is handled expertly in-studio to preserve the ring’s integrity and comfort.
