Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set three-stone ring foundation awaits your choice of a 6 x 3 mm center stone, designed to showcase the marquise’s signature drama and hand-flattering elongation.

Crafted in 18K white gold, the mounting features delicate prongs and a subtly raised gallery that balances presence with everyday wearability. The band’s smooth finish and moderate width ensure comfort, while the three-stone setting offers a harmonious frame for your selected center and side stones, emphasizing brilliance without bulk.

Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets artisan care. The lab-grown diamond option aligns with a commitment to ethical sourcing and environmental mindfulness, reflecting a modern approach to fine jewelry.

Ideal for those who appreciate sculptural elegance and a ring that sits close to the finger, this setting complements slender to medium finger sizes and layers beautifully with stacking bands. Its low-profile design also makes it glove-friendly for daily wear.

Should you need resizing, our in-house jewelers provide expert adjustments to ensure a seamless fit without compromising the setting’s integrity.
