Lab-Grown Diamond Engagement Ring

The elongated silhouette of a 12 x 6 mm marquise diamond catches the eye like a whispered secret, its tapered points drawing light into a graceful, dramatic sparkle. This semi-set engagement ring offers a refined foundation in 10K white gold, hand-shaped and polished in our Williamsburg studio to a smooth, low-profile band that rests comfortably against the finger.

Each accent setting is meticulously crafted to complement the marquise’s distinctive shape, enhancing its vintage-inspired allure without overwhelming the stone’s natural brilliance. The band’s subtle curvature and precise finishing ensure a secure fit that pairs effortlessly with wedding bands or stackable rings.

Our commitment to sustainability is reflected in the choice of a lab-grown diamond, offering clarity and fire with a significantly reduced environmental footprint. This ring’s design suits those who appreciate artisan detail and a piece made for everyday wear, especially hands that favor elegance without excess height.
