Main DescriptionThis professional-grade jewelry CAD asset features a sophisticated solitaire engagement ring design characterized by an emerald cut center stone held in a secure four-prong setting. The architectural highlight of the model is a fluid, intertwined bypass split-shank that seamlessly integrates with the basket layout. This design maximizes structural durability while maintaining an elegant, continuous profile, ensuring that the final physical piece offers excellent balance and comfort on the finger.

Engineered strictly according to modern jewelry manufacturing constraints, the model guarantees uniform wall thickness and optimal material distribution. The sweeping wire profiles avoid thin, brittle cross-sections, minimizing porosity risks during vacuum casting. Prongs are intentionally left elongated and upright to provide setting masters with sufficient material to seat, trim, and burnish over the emerald cut gemstone flawlessly.

The model's geometric integrity has been completely optimized and verified using industrial software. All contact zones between the bypass shank and the central basket are completely booleand and unified. This strict engineering approach ensures a reliable transition from digital file to high-resolution resin or wax 3D printing, eliminating the casting failures common with unoptimized models.
