Elegant elongated cushion-cut solitaire engagement ring CAD model featuring a large cushion center stone secured by a clean four-prong structure. The open gallery and simple polished shank create a refined contemporary solitaire design that keeps the elongated center diamond as the primary visual focus.

The model is suitable for 3D printing, casting, diamond setting, polishing, finishing, and custom engagement-ring manufacturing. Center stone dimensions, prong configuration, ring size, and metal type can be adjusted according to production requirements.

If you would like any changes or specific customizations to this design, we would be happy to make them for you.
