Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a subtle, tapered glow that draws the eye along the finger’s natural line. This semi-set engagement ring in 18K rose gold offers a delicate framework designed to showcase a 10 x 5 mm marquise center stone of your choosing.

Crafted with a low-profile setting, the band sits close to the hand, reducing snagging and enhancing comfort for everyday wear. The rose gold’s warm blush complements the diamond’s brilliance while the mounting’s precise prong work ensures security without bulk. Each piece is finished by hand in our Williamsburg studio, inspected for smooth edges and balanced fit.

Our lab-grown diamonds provide the same optical clarity and sparkle as mined stones, with a fraction of the environmental impact—an ethical choice that quietly elevates your commitment.

Ideal for those who appreciate a refined silhouette, this ring’s slender band and subtle accents harmonize with slender or average finger shapes, and its low profile fits easily under gloves or alongside stackable bands.

Should you need resizing, our in-house artisans accommodate adjustments with care to maintain structural integrity. Typical lead times reflect the custom nature of your design.
