Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc. This semi-set engagement ring foundation in 18K white gold frames a 10 x 5 mm center stone with subtle accent details that emphasize clarity and modern structure.

Crafted in Williamsburg, the band’s sleek profile offers a refined comfort fit, designed to sit low against the finger for everyday wear without catching. Each curve and facet is carefully finished by hand, ensuring a polished surface that complements the diamond’s dramatic shape.

Our commitment to ethical jewelry is reflected in the use of lab-grown diamonds, which provide exceptional brilliance with a reduced environmental footprint.

The elongated marquise shape naturally elongates the hand, making this setting ideal for those seeking a confident yet understated statement. Its low-profile design pairs seamlessly with stacking bands or a wedding ring, while the 18K white gold lends a cool, contemporary edge.

Should you wish to customize the fit, resizing is available to ensure the ring feels as effortless as it looks.
