Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that draws the eye along the finger’s natural line. This semi-set solitaire ring offers a refined foundation in warm 18K rose gold, designed to cradle a 10 x 5 mm marquise stone with precision.

Crafted with a low-profile setting, the band sits close to the hand, minimizing snagging while maximizing comfort for everyday wear. The rose gold shank is smoothly finished, its gentle curve balanced for a secure fit without bulk. Each mounting undergoes meticulous inspection in our Williamsburg studio to ensure flawless alignment and durability.

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

Ideal for those who appreciate a sleek silhouette and subtle elegance, this solitaire mounting complements slender fingers and pairs effortlessly with stacking bands or wedding rings. Its modest height makes it glove-friendly and unobtrusive for active lifestyles.

Should you wish to adjust the fit, resizing is available with care to maintain the band’s integrity and finish.
