Design Inspiration & AestheticThis elegant engagement ring design puts a sophisticated twist on the classic solitaire. It features a stunning 8x7mm oval-cut center stone (approx. 1.5–1.75 ct diamond equivalent) held by a refined six-prong cathedral setting. The hallmark of this design is the intricate milgrain-style beaded inner sleeve and the vertical gear-track texturing along the interior of the shank, providing a hidden luxury detail that offers a unique tactile experience for the wearer while maintaining a polished, minimalist exterior.
3D Modeling & CAD TechnicalsThe model has been precision-engineered in MatrixGold/Rhino to ensure professional-grade geometry. It features a finger size of 16.00mm (approx. US size 5.5), but the shank includes a smooth sizing bar at the base for easy physical resizing. The CAD file maintains high-fidelity NURBS data for the .3dm format and high-poly tessellation for .STL and .OBJ files, ensuring that the beaded details and prong tips are crisp and free of manifold errors. The stone proportions are optimized for standard oval cuts, ensuring a flush and secure seat.
Manufacturing & CastingThis design is fully optimized for 3D printing (DLP/SLA) and investment casting. The inner beaded detail is strategically spaced to ensure clean burnout and easy polishing.
Metal Weights: The design is robust yet refined, weighing approximately 3.77g in 14K White Gold and 4.38g in 18K White Gold.
Assembly: It is a single-piece casting (monolithic), which reduces labor costs and assembly time while increasing structural integrity. The six-prong head provides superior security for the oval gemstone compared to traditional four-prong settings.
