General DescriptionA premium, high-quality 3D model of an extravagant and luxurious statement engagement ring. This masterpiece features a massive elongated cushion-cut center stone, gracefully elevated by a 4-prong setting that includes a sparkling hidden halo. The true standout feature is the intricate, wide eternity-style band, which showcases a central row of horizontally set emerald or baguette-cut stones, beautifully framed by two outer rows of round pavé-set diamonds.

This model is meticulously crafted with precise technical proportions, intended for high-end fine jewelry manufacturing. It is optimized for high-resolution resin 3D printing (SLA/DLP) and investment casting in precious metals.

Technical Specifications & DimensionsThe dimensions have been rigorously calculated to accommodate the complex stone setting while maintaining structural integrity:

Ring Size: Inner diameter of 17.33 mm (Equivalent to US Size 7).

Band Width: 4.90 mm (consistent width accommodating the three rows of stones).

Hidden Halo / Gallery Rail: 1.00 mm thickness, designed to hold round accent stones.

Center Stone Setting: Length of approximately 11.15 mm, designed to accommodate a large Elongated Cushion-cut diamond or gemstone.

Model Features3D Print Ready: The mesh is fully closed (watertight), free of non-manifold edges, and contains no geometry errors. Ready for immediate import into any 3D printing slicer.

Advanced Stone Setting: Features pre-cut seats and precisely engineered prongs/channels for a complex multi-stone layout (baguettes/emeralds and round brilliants). Note: Due to the high number of stones, this design is recommended for experienced jewelers and diamond setters.
