This engagement ring design features a refined three-stone layout centered around an elegant marquise-cut gemstone, accented by two round side stones for added brilliance and visual balance. The marquise cut, known for its elongated silhouette and pointed ends, enhances finger coverage while delivering a distinctive and sophisticated appearance suited for modern and classic bridal collections.

The center stone is secured using a carefully engineered prong arrangement that protects the tips while allowing maximum light entry for strong brilliance. Round accent stones positioned on each side soften the transition into the band and introduce additional sparkle without overpowering the center stone.

The band profile is designed for comfortable everyday wear while maintaining proper metal thickness for casting durability and finishing efficiency. Smooth shoulder transitions and a well-balanced gallery structure provide both aesthetic refinement and manufacturing reliability.

The CAD model is optimized for jewellery production workflows, featuring clean surfaces, accurate stone seating, and geometry suitable for resizing or customization. The design can easily be adapted for different stone dimensions or client-specific modifications.

This model is ideal for jewellery manufacturers, CAD designers, custom jewellery studios, and retailers seeking production-ready engagement ring designs for premium collections.
