Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shimmer that seems to stretch beyond the finger. This semi-set halo engagement ring in 10K yellow gold frames a 7 x 3.5 mm marquise stone, its pointed ends drawing the eye along a graceful, almost poetic line.

Crafted with a low-profile halo setting, the band’s gentle curve ensures a comfortable fit for daily wear, while the polished yellow gold offers a warm glow that complements the diamond’s crisp facets. Each piece is meticulously finished by hand in our Williamsburg studio, where precision meets quiet artistry.

Choosing a lab-grown diamond means embracing clarity and brilliance without compromise, reflecting a commitment to ethical jewelry that honors both beauty and sustainability.

The slender shape of the marquise naturally elongates the finger, making this ring especially suited for those who appreciate refined elegance with a subtle statement. Its halo setting adds a soft radiance, perfect for stacking or wearing solo with ease.

Should you need resizing, our in-studio experts ensure a seamless adjustment without disrupting the ring’s delicate balance.
