Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its tapered points tracing a delicate arc that seems to stretch the fingers with quiet elegance. Nestled within a halo of finely set pavé stones, this 7 x 3.5 mm center sparkles with a subtle fire, framed by a 14K white gold band that balances cool sophistication with everyday grace.

Crafted in Williamsburg, each ring is meticulously finished to a smooth comfort fit, ensuring it sits low and secure for daily wear. The halo setting enhances brilliance without adding bulk, making it glove-friendly and ideal for stacking alongside wedding bands or delicate bracelets.

Our diamonds are lab-grown, offering clarity and sparkle with a significantly reduced environmental footprint. This ring embodies a thoughtful approach to luxury—ethical, radiant, and designed for a life well-lived.

Its slender profile suits hands that appreciate refined geometry and a touch of vintage-inspired romance, perfect for those drawn to shapes that elongate and flatter. Resizing is available to ensure a precise fit, crafted with care in our Brooklyn studio.
