Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it draws the eye along a graceful arc—an elegant statement of refined drama. This semi-set solitaire ring offers a sleek foundation crafted from warm 18K rose gold, designed to cradle a 9 x 4.5 mm marquise center with precision and poise.

The band’s low-profile setting ensures the diamond sits close to the finger, reducing snagging and enhancing everyday comfort. Expertly finished in Williamsburg, the smooth shank balances durability with a subtle gleam, while the secure prongs are engineered for lasting wear.

Each lab-grown diamond embodies clarity and brilliance without the environmental cost of traditional mining, reflecting a commitment to ethical jewelry that aligns with modern values.

Ideal for those who appreciate a confident yet understated look, this mounting suits slender to medium finger sizes and pairs effortlessly with stacking bands or a wedding ring. Its streamlined design fits comfortably under gloves or sleeves, making it a practical choice for daily life.

Should you wish to adjust the fit, resizing is available through our Brooklyn studio with care taken to preserve the ring’s integrity.
