This Marquise Halo Engagement Ring CAD model showcases a refined and elongated design, centered with a stunning marquise cut diamond surrounded by a delicate halo of round accent stones. The marquise shape enhances finger length visually, offering a sophisticated and graceful bridal aesthetic.

The center stone is secured with precisely engineered prongs positioned to protect the pointed tips—ensuring both elegance and durability. The halo frame enhances brilliance by reflecting light into the center stone, creating maximum sparkle from every angle.

The shank features a continuous micro-pave diamond setting that flows seamlessly along the band. The stones are evenly spaced with proper seat depth to ensure secure setting and clean finishing after casting. The elevated gallery structure supports the halo and allows optimal light entry beneath the stone.

The basket is carefully structured for strength while maintaining a lightweight and balanced profile. Proper metal thickness and smooth transitions make this model suitable for high-quality casting and professional production.

This design is ideal for jewellery manufacturers, retailers, and CAD professionals looking for a premium marquise halo engagement ring ready for customization and production.
