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 rose gold offers a modern-minimal framework, where clean lines and structural clarity meet quiet confidence.

Crafted in Williamsburg, the band’s warm rose hue is polished to a soft glow, complementing the marquise’s distinctive 12 x 6 mm shape—an elegant balance of drama and refinement. The three-stone setting is designed with precision to cradle your chosen center stone securely, while maintaining a low profile that slips comfortably beneath gloves or daily wear.

Each piece is finished by hand and inspected meticulously, ensuring smooth edges and a comfort fit that feels natural on the finger. The rose gold’s subtle blush enhances the diamond’s brilliance without overwhelming it, making this mounting a versatile foundation for a statement ring or a stackable addition.

Our commitment to lab-grown diamonds means your ring begins with a stone of exceptional clarity and ethical provenance, reflecting a sustainable approach without compromise.

Ideal for those who appreciate architectural elegance and understated strength, this mounting suits hands that favor elongated shapes and a refined silhouette. Resizing is available to ensure a perfect fit, crafted with care in our Brooklyn studio.
