Lab-Grown Diamond Engagement Ring

Light catches the elongated marquise diamond, its tapered points drawing the eye along a graceful arc that complements the hand’s natural lines. This 9 x 4.5 mm center stone is framed by a delicate halo of pavé-set lab-grown diamonds, enhancing brilliance without adding bulk.

Crafted in 14K white gold, the ring features a low-profile setting designed for everyday wear. The smooth comfort-fit band and secure prong setting ensure the piece sits close to the finger, minimizing snagging and maximizing ease of movement. Each element is meticulously finished and inspected in our Williamsburg studio, where precision meets subtlety.

Our lab-grown diamonds offer the clarity and sparkle of mined stones with a significantly reduced environmental footprint, reflecting a commitment to ethical jewelry without compromise.

This engagement ring suits those who appreciate refined geometry paired with practical design—ideal for hands that favor slender, elongated shapes and a ring that layers effortlessly with wedding bands or stackable rings. Its low profile makes it glove-friendly and unobtrusive for daily life.

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