Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a cushion-cut diamond, its gentle glow unfolding like a quiet promise. This three-stone semi-set engagement ring in platinum frames an 8 x 8 mm center stone with two delicately balanced side gems, each held in a low-profile setting that keeps the silhouette sleek and wearable.

Crafted in our Williamsburg studio, the platinum band is hand-finished to a satiny smoothness, designed for comfort and everyday grace. The three-stone arrangement offers a subtle narrative of past, present, and future, while the secure prong setting ensures the diamonds sit close to the finger without excess height.

Each lab-grown diamond reflects our commitment to ethical jewelry, offering clarity and brilliance with a smaller environmental footprint. The cushion shape’s soft edges and vintage-inspired facets lend a warm, inviting sparkle that complements a variety of hand shapes.

Ideal for those who appreciate artisanal detail and a ring that layers effortlessly with other bands, this design balances statement with subtlety. Its comfort fit and modest profile make it glove-friendly and suited to daily wear.

Should you wish to adjust the fit, resizing is available through our Brooklyn studio with care tailored to platinum’s unique properties. Typical lead times for completion are shared during your consultation.
