A manufacturing-ready oval-cut engagement ring CAD model featuring a large oval center stone secured with four prongs. A delicate hidden halo of round accent stones is positioned beneath the center stone, adding extra sparkle while maintaining a clean solitaire appearance from the top.

The open gallery allows light to enter the center stone and provides practical access for setting, cleaning and finishing. The smooth rounded shank creates a timeless bridal design suitable for gold, platinum and other precious-metal production.

This model is suitable for resin printing, lost-wax casting, mold making, stone setting and professional jewelry manufacturing. Prongs, stone seats, tolerances and casting shrinkage should be reviewed according to the selected stones and production method.

Files included in STL and editable 3DM formats.
