Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc that feels both bold and refined. This semi-set engagement ring foundation in 18K white gold offers a modern-minimal frame designed to highlight a 10 x 5 mm marquise center stone of your choosing, accented subtly to enhance clarity and structure without distraction.

Crafted in Williamsburg, the band is polished to a soft sheen with a low-profile setting that rests comfortably against the finger, ideal for daily wear and easy layering. The clean lines and precise angles reflect a quiet confidence, while the secure prong setting ensures your stone remains the focal point.

Each piece is finished by hand and inspected meticulously, embodying the studio’s commitment to thoughtful craftsmanship. The lab-grown diamond option aligns with a sustainable ethos, offering brilliance without compromise.

Designed for those who appreciate architectural elegance and understated strength, this mounting suits a variety of hand shapes and sizes, especially those seeking a ring that balances presence with wearability. Its slim profile pairs well with stackable bands or a simple wedding band.
