This sophisticated marquise cut halo engagement ring CAD design features a clean open gallery structure with refined halo detailing. The marquise-shaped center stone is set securely in a strong prong setting, enhancing its elongated brilliance while allowing maximum light entry from all angles.

The open gallery beneath the center stone adds both visual depth and functional light performance, making the design elegant and modern. A delicate halo with precisely placed accent stones frames the center stone, adding extra sparkle without overpowering the overall silhouette. The smooth, well-balanced band ensures comfort and durability for daily wear.

This CAD model is professionally engineered for jewellery manufacturing, with accurate stone seats, optimized wall thickness, and clean geometry to ensure reliable casting and high-quality finishing. The design is suitable for yellow gold, white gold, and rose gold, and can be easily customized for different stone sizes, metals, or ring dimensions.

Ideal for engagement rings, bridal jewellery collections, and luxury custom jewellery production.
