This Princess Halo Engagement Ring CAD model features a bold and elegant design centered around a princess-cut diamond. The sharp square geometry of the center stone delivers a modern and sophisticated look while maintaining exceptional brilliance.

The princess-cut center stone is secured with four strong corner prongs designed to protect the edges and ensure long-term durability. A precisely aligned halo of round accent diamonds surrounds the center stone, enhancing overall sparkle and creating a larger visual appearance.

The band is adorned with micro pave diamonds along the upper shank, providing continuous brilliance from every angle. The elevated gallery structure allows maximum light entry beneath the center stone, improving fire and reflection. The basket and under-gallery are engineered with balanced metal thickness to ensure casting strength while maintaining a refined profile.

This CAD model is optimized for professional jewellery manufacturing, with clean geometry and accurate stone seats for smooth production, setting, and polishing. The design can be easily resized or customized according to specific stone dimensions.

Ideal for engagement collections, bridal jewellery lines, and custom manufacturing projects.
