This Round Halo Diamond Engagement Ring CAD model features a timeless circular silhouette enhanced by a perfectly proportioned round diamond halo. The round brilliant center stone is secured in a refined four-prong setting, designed to maximize light performance while ensuring strong structural integrity for manufacturing.

The halo frame is carefully aligned to maintain symmetry and consistent spacing around the center stone, amplifying brilliance and creating a bold visual presence. Round accent diamonds are evenly distributed throughout the halo and continue along the shoulders in a pavé setting, delivering continuous sparkle from every angle.

The elevated gallery structure allows optimal light entry beneath the center stone while providing reliable support during casting and everyday wear. The under-gallery framework is engineered for durability and secure stone placement. The shank features a smooth comfort-fit interior with optimized thickness suitable for gold, platinum, or other precious metal production.

This CAD model is production-ready with clean topology, accurate stone seats, and precise prong alignment. It is ideal for jewellery manufacturers, retailers, and CAD designers seeking a classic halo engagement ring with modern detailing. The design can be resized and customized for various stone dimensions and finger sizes without compromising structural strength.
