Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a marquise diamond catching light with every turn of the hand—its tapered points lending a quiet drama to your engagement ring.

This semi-set foundation in 18K white gold is crafted with a low-profile bezel setting designed for everyday wear, balancing secure hold with a sleek silhouette. The band’s smooth finish and comfort fit ensure it rests naturally, whether worn solo or paired with stacking bands.

Our lab-grown diamonds offer the clarity and brilliance of mined stones while reflecting a commitment to sustainable, ethical jewelry.

Measuring 10 by 5 millimeters, the marquise shape visually elongates the finger, flattering a variety of hand sizes with its architectural grace. The mounting’s subtle accents add refined detail without compromising its streamlined form.

Should you need resizing, our Brooklyn studio handles adjustments with care to maintain the ring’s integrity and comfort.
