Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond catching light as it elongates the finger, framed by a delicate halo that amplifies its tapered brilliance. This semi-set platinum mounting awaits your choice of a 6 x 3 mm marquise center, crafted with precision in our Williamsburg studio where every curve is hand-finished to a smooth, low-profile silhouette.

The halo setting enhances sparkle without adding bulk, while the platinum band offers enduring strength and a cool, comforting weight against the skin. Its artisan construction ensures a secure, glove-friendly fit ideal for daily wear, balancing elegance with practicality.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that combine clarity with sustainability. This mounting suits those who appreciate refined geometry and a ring that layers effortlessly with other bands or stands strikingly alone.

Should you need resizing or prefer a custom finish, our Brooklyn workshop accommodates adjustments with care and transparency. Lead times are tailored to your design choices, ensuring a thoughtful, pressure-free experience.
