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 semi-set three-stone engagement ring foundation in 18K yellow gold invites your choice of a 10 x 5 mm center stone, ready to become a personal emblem of commitment.

Handcrafted in our Williamsburg studio, the band’s warm gold gleams with a subtle polish that balances artisanal texture and refined finish. The three-stone setting is designed with low-profile prongs that cradle each gem securely while maintaining a sleek profile, ideal for daily wear without catching or discomfort.

Each lab-grown diamond offers the clarity and brilliance of mined stones but with a lighter environmental footprint, reflecting a quiet commitment to ethical jewelry.

The gently curved band fits comfortably on the finger, its modest width allowing effortless stacking or solo elegance. The marquise shape’s elongated form visually lengthens the hand, making it a thoughtful choice for those who appreciate architectural lines with a touch of drama.

Should you need resizing or prefer a custom stone cut, our Brooklyn studio provides attentive adjustments and guidance to ensure your ring fits seamlessly into your life.
