Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a delicate dance of light that feels both intimate and expansive. This five-stone semi-set engagement ring in 10K yellow gold frames an 8 x 4 mm marquise center, its tapered points drawing the eye along the finger with subtle elegance.

Crafted with a low-profile setting, the band’s gentle curve ensures a comfortable fit for daily wear, while the warm glow of yellow gold complements the diamond’s crisp facets. Each side stone is carefully positioned to enhance the center’s architectural grace without overwhelming it, finished by hand in our Williamsburg studio where every detail is refined and inspected.

Choosing a lab-grown diamond means embracing clarity and brilliance with a lighter environmental footprint, reflecting a modern approach to ethical jewelry.

This ring suits those who appreciate a slender, elongating shape that flatters a variety of hand sizes and pairs effortlessly with stacking bands or a wedding band. Its low profile makes it glove-friendly and unobtrusive for everyday life.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure your ring fits just right without compromising its delicate balance.
