Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to cradle the hand. This semi-set three-stone engagement ring foundation in warm 18K yellow gold invites your choice of center stone, designed to highlight the marquise’s graceful drama and vintage allure.

Crafted with a low-profile setting, the band’s smooth contours ensure comfort for daily wear while the three-stone layout balances presence with subtlety. Each prong is meticulously shaped and polished in our Williamsburg studio, where every detail is inspected to meet exacting standards of finish and durability.

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

The slender band suits hands that appreciate refined elegance and pairs effortlessly with stacking rings or a wedding band. Its gentle rise and secure setting make it glove-friendly and ideal for those seeking a ring that moves seamlessly from morning light to evening glow.

Should you wish to adjust sizing, our in-studio experts ensure a precise fit without altering the ring’s delicate proportions.
