Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This 9 x 4.5 mm center stone is framed by a delicate halo, amplifying its architectural brilliance with a modern-minimal clarity.

Set in warm 14K rose gold, the ring’s low-profile halo setting balances bold geometry with everyday wearability. The band’s smooth finish and comfort fit ensure it sits naturally against the skin, while the secure prong setting highlights the diamond’s crisp facets without excess metal.

Crafted in our Williamsburg studio, this engagement ring features a lab-grown marquise diamond—cultivated with precision to mirror the fire and scintillation of mined stones, yet with a lighter environmental footprint.

Its slender shape and refined halo make it ideal for those who appreciate structured elegance that complements slender fingers or pairs seamlessly with stackable bands. The ring’s design is glove-friendly and crafted for daily life, marrying form and function.

Should you need a custom fit, resizing is available to ensure comfort without compromising the ring’s clean lines.
