Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, its tapered points drawing the eye along a graceful silhouette that feels both bold and refined. This 12 x 6 mm center stone is embraced by a halo of delicate pavé, amplifying its signature brilliance without adding bulk.

Crafted in 14K yellow gold, the ring’s low-profile setting ensures it sits close to the finger, balancing presence with everyday comfort. The smooth band curves gently, designed for a secure fit that resists snagging and layers effortlessly with other pieces.

Each diamond is lab-grown, offering a clarity and sparkle indistinguishable from mined stones, while aligning with a commitment to sustainability and ethical sourcing.

Ideal for those who appreciate a statement ring that remains practical—its streamlined silhouette complements slender and average finger shapes alike, and the halo setting enhances the marquise’s natural elongation.

Should you need a size adjustment, our Brooklyn studio handles resizing with care to maintain the ring’s structural integrity and finish.
