Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that dances with every movement. This semi-set halo engagement ring foundation in 10K yellow gold frames a center stone measuring 15 by 7.5 millimeters, designed to amplify the marquise’s signature tapered drama and graceful elongation of the finger.

Crafted with a delicate halo setting in mind, the band’s warm yellow gold offers a subtle contrast to the diamond’s sharp geometry, while the low-profile mounting ensures daily wearability without catching. Each curve and prong is meticulously finished in our Williamsburg studio, where comfort meets refined craftsmanship in a piece meant to be worn close to the skin.

Choosing a lab-grown diamond for this setting reflects a commitment to ethical jewelry—minimizing environmental impact while celebrating clarity and brilliance. The semi-set design invites you to select a center stone that resonates personally, allowing for a truly bespoke expression.

Ideal for those who appreciate a statement ring that remains elegant and glove-friendly, this halo style balances boldness with subtlety, pairing effortlessly with stackable bands or worn solo. The elongated marquise shape flatters a variety of hand sizes, enhancing natural grace.

Should resizing be needed, our in-studio experts ensure a seamless adjustment without compromising the ring’s integrity. Typical lead times accommodate careful customization and finishing.
