Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc across the finger. This semi-set halo engagement ring in 18K rose gold frames a 10 x 5 mm marquise center stone, inviting your choice of lab-grown brilliance to complete its artisan-crafted embrace.

Hand-forged in our Williamsburg studio, the band’s warm rose gold is meticulously polished to a soft glow, complementing the halo’s intricate pavé setting that enhances the diamond’s length and sparkle. The low-profile design ensures comfortable daily wear, while the secure prongs cradle the stone with precision, reflecting careful inspection at every stage.

Crafted with lab-grown clarity, this ring honors sustainability without compromise, embodying a modern approach to ethical jewelry.

Its slender band and elongated shape flatter a variety of hand sizes, offering a graceful fit that pairs effortlessly with stackable bands or stands alone as a statement of refined taste. The halo setting adds dimension without bulk, making it glove-friendly and suited for everyday life.

Should you need resizing, our in-studio experts provide seamless adjustments to ensure your ring fits perfectly.
