Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise shape, casting a subtle drama that draws the eye along its graceful silhouette. This semi-set solitaire ring in 10K yellow gold awaits your choice of an 8 x 4 mm lab-grown diamond, offering a refined balance between presence and wearability.

Crafted with a low-profile setting, the band sits close to the finger for everyday comfort without sacrificing brilliance. The smooth finish and secure prongs ensure durability, while the warm gold tone complements the stone’s fiery sparkle. Each piece is meticulously inspected in our Williamsburg studio to meet exacting standards.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, reducing environmental impact without compromising clarity or beauty.

Designed for those who appreciate subtle elegance, this ring’s slender band and modest height make it ideal for stacking or pairing with a wedding band. Its shape elongates the finger, enhancing natural grace while remaining glove-friendly.
