Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your hand framed by a 9 x 4.5 mm marquise diamond, its tapered points softened by a delicate halo that catches light with quiet precision. This semi-set engagement ring foundation in 10K yellow gold offers a low-profile silhouette designed for everyday grace.

Crafted with a focus on comfort and durability, the band’s gentle curve and secure prong setting ensure the stone sits close to the finger, minimizing snagging while maximizing wearability. Each piece is meticulously finished in our Williamsburg studio, where expert hands inspect every detail before it leaves the bench.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, combining clarity and sustainability without compromise. The marquise shape lends a refined drama, elongating the finger with its elegant, pointed form—ideal for those who appreciate architectural lines paired with subtle sparkle.

This ring suits a wearer who values a balance of statement and practicality, pairing effortlessly with stackable bands or standing alone with quiet confidence. Its low profile makes it glove-friendly and comfortable for daily life.
