This premium cushion halo diamond engagement ring CAD design is created to deliver a bold, luxurious presence with refined craftsmanship. The design features a round center stone framed by a cushion-shaped halo, enhanced further by a split shank band adorned with precisely aligned micro diamonds. The layered halo structure adds depth, brilliance, and a high-end bridal appeal.

Every element of the ring is modeled with real jewellery manufacturing in mind. Accurate stone seats, well-balanced prongs, smooth inner comfort fit, and optimized wall thickness ensure dependable casting and secure stone setting. The split shank not only elevates the visual elegance but also strengthens the structure for long-term wear.

This CAD model is suitable for high-end engagement, bridal, and statement ring collections. Clean geometry and professional topology allow smooth finishing, polishing, and easy customization. The design can be resized or modified for stone size, band width, or overall proportions as required by jewellers and brands.
