Lab-Grown Diamond Engagement Ring

Light catches the elongated marquise shape, casting a slender, graceful silhouette that seems to float above the finger. This semi-set solitaire ring offers a refined foundation in 14K white gold, its cool sheen a quiet contrast to the warm glow of rose gold accents, inviting your choice of a 9 x 4.5 mm marquise diamond to complete the vision.

Crafted with a low-profile setting, the band’s subtle curvature ensures comfort for daily wear while allowing the stone’s tapered points to command attention without overwhelming. Each piece is meticulously finished in our Williamsburg studio, where hand polishing and precision inspection guarantee a smooth, enduring surface.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint.

The slender shape and moderate size suit hands seeking elegance without excess, pairing effortlessly with stackable bands or worn solo for understated drama. Its balanced proportions make it glove-friendly and ideal for those who favor a sleek, modern silhouette.
