Lab-Grown Diamond Engagement Ring

Imagine the delicate silhouette of a marquise diamond, its elongated shape catching light like a whispered secret across your hand. This semi-set halo engagement ring in 14K white gold frames a 7 x 3.5 mm marquise center with a circle of finely crafted pavé stones, enhancing its graceful taper and lending a soft glow that dances with every movement.

Hand-forged in Williamsburg, the band’s low-profile setting ensures a comfortable fit beneath gloves or daily wear, while the smooth finish and subtle curvature invite effortless stacking alongside other favorites. Each prong is meticulously shaped and polished, reflecting the studio’s commitment to precision and enduring craftsmanship.

Our lab-grown diamonds offer the same brilliance and clarity as mined stones, with a lighter environmental footprint and transparent origins, aligning with a mindful approach to fine jewelry.

This ring suits those who appreciate a refined statement—elongating the finger with architectural elegance yet grounded in everyday practicality. Its halo setting amplifies sparkle without adding bulk, making it an ideal choice for a hand that values both beauty and ease.

Should you wish to adjust the band size, resizing is available with care to preserve the ring’s delicate balance and finish.
