Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated facets of a marquise diamond, it casts a striking silhouette that both sharpens and softens the hand’s natural lines. This semi-set engagement ring offers a refined foundation in 18K yellow gold, designed to cradle a 9 x 4.5 mm marquise stone with precision and grace.

The band’s low-profile setting ensures the diamond sits close to the finger, reducing snagging and enhancing everyday comfort. Expertly crafted in Williamsburg, the smooth shank balances durability with a subtle curve that feels natural against the skin. Each piece undergoes meticulous finishing and inspection to meet exacting standards of fit and finish.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, combining brilliance with a reduced environmental footprint.

This ring suits those who appreciate architectural elegance paired with practical wearability—ideal for slender to medium finger sizes and compatible with stacking bands or wedding rings of similar profile. Its streamlined silhouette fits comfortably under gloves or sleeves, making it a versatile choice for daily life.

Should you wish to adjust the band size, resizing is handled with care to preserve the integrity of the setting and metal.
