Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise diamond, casting a delicate silhouette that feels like a whispered promise. This three-stone engagement ring, set in cool platinum, balances architectural grace with intimate warmth.

Each diamond is securely nestled in a low-profile setting, allowing the center stone’s 10 x 5 mm marquise shape to elongate the finger with subtle drama. The platinum band is hand-polished to a satin finish, offering a smooth comfort fit that wears effortlessly day to day. Crafted and inspected in our Williamsburg studio, the ring reflects meticulous attention to detail and refined craftsmanship.

Our diamonds are lab-grown, embodying clarity and brilliance while honoring a commitment to sustainability and ethical sourcing.

Designed for those who appreciate a blend of modern geometry and romantic symbolism, this ring pairs beautifully with slender bands or stands strikingly alone. Its low profile and secure setting make it glove-friendly and ideal for daily wear.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure a perfect fit without compromising the ring’s elegant lines.
