Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set three-stone ring foundation in 14K white gold awaits your choice of a 6 x 3 mm center stone, ready to frame it with two delicate side gems that enhance its sculptural elegance.

Crafted in our Williamsburg studio, the band’s smooth comfort fit and low-profile setting ensure daily wearability without sacrificing presence. Each curve is hand-finished to a soft sheen, balancing strength with subtlety, while the prongs are precisely shaped to cradle your center stone securely.

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

This design suits those who appreciate architectural lines and a refined silhouette that elongates the finger. Its slender band layers effortlessly with other rings or stands alone as a statement of modern romance.

Should you need resizing, our in-studio artisans provide careful adjustments to maintain the ring’s integrity and comfort.
