Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with subtle drama. This semi-set engagement ring frame in 18K yellow gold awaits your choice of a 9 x 4.5 mm marquise center, designed to cradle the stone securely while maintaining a low profile for everyday ease.

Crafted with precision in Williamsburg, the band’s smooth finish and balanced weight ensure comfort without sacrificing presence. The setting’s gentle curve and secure prongs keep the diamond close to the hand, minimizing snagging and making it ideal for daily wear. Accents along the shank add refined detail without overwhelming the stone’s distinctive shape.

Each ring foundation supports a lab-grown diamond, reflecting a commitment to ethical sourcing and sustainability without compromising brilliance or clarity. The marquise cut’s elongated form visually lengthens the finger, flattering a variety of hand shapes and sizes.

Its streamlined silhouette pairs well with stacking bands or stands confidently alone, while the comfort fit band adapts naturally to movement. Resizing is available to ensure a precise fit, crafted with care in our Brooklyn studio.
