This elegant Round Diamond Halo Engagement Ring CAD Design showcases a classic round brilliant center stone surrounded by a perfectly balanced halo of pavé-set diamonds. The halo enhances overall brilliance and visual size while maintaining a timeless and sophisticated appearance suitable for premium bridal jewellery.

The round center stone is secured in a strong, well-proportioned prong setting that allows maximum light entry and long-term stone security. The pavé-set diamonds along the shank add continuous sparkle and seamlessly connect the band to the elevated halo head, creating a harmonious and refined profile.

The ring structure is carefully engineered for professional jewellery manufacturing. The under-gallery is open and optimized to support smooth metal flow during casting, accurate stone setting, and efficient polishing access. All wall thicknesses, prong dimensions, and pavé spacing are designed to meet industry production standards.

This CAD model is ideal for engagement rings, bridal collections, and luxury fine jewellery. It supports easy customization for ring size, center stone diameter, halo thickness, pavé density, and metal type, making it suitable for both bespoke orders and scalable commercial production.
