Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed tips tracing a delicate arc that seems to cradle the hand. This three-stone semi-set engagement ring in warm 10K yellow gold offers a graceful foundation for a 9 x 4.5 mm marquise center, poised to reflect light with a subtle, refined brilliance.

Crafted with a low-profile setting, the band’s gentle curve ensures comfort for daily wear while the three-stone design balances presence with elegance. Each prong is meticulously finished by hand in our Williamsburg studio, ensuring the mounting is both secure and smooth against the skin.

Our diamonds are lab-grown, embodying clarity and sustainability without compromise—an ethical choice that honors both beauty and responsibility.

The slender yellow gold band complements elongated fingers and suits those who appreciate a ring that layers effortlessly with wedding bands or stackable styles. Its modest height makes it glove-friendly and unobtrusive, ideal for a life in motion.

Should you wish to adjust the fit, resizing is available with care to preserve the ring’s delicate balance and finish.
