Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a sleek, modern halo. This 12 x 6 mm center stone rests in a 14K white gold setting, where a delicate halo of pavé diamonds amplifies its architectural brilliance without overwhelming the design.

Crafted with precision in our Williamsburg studio, the low-profile setting ensures the ring sits comfortably for daily wear, while the smooth band offers a subtle weight that balances presence with ease. Each facet is carefully inspected to maintain clarity and sparkle, reflecting a quiet confidence in every angle.

Our lab-grown diamonds embody a commitment to ethical sourcing and sustainability, offering the same optical purity as mined stones with a lighter environmental footprint.

The elongated marquise shape flatters slender fingers and pairs effortlessly with stackable bands or wedding rings of varied profiles. Its streamlined silhouette is glove-friendly and designed for those who appreciate refined geometry with a modern edge.

Should you require resizing, our in-house artisans provide expert adjustments to ensure a perfect fit without compromising the ring’s integrity.
