A Masterpiece of Elegance and SymbolismPresenting a masterfully crafted 3D model of a luxurious three-stone engagement ring. This breathtaking design features a sweeping, organic trellis setting that gracefully elevates the center stone while seamlessly integrating two elegant pear-shaped side stones. Often representing the past, present, and future, the three-stone arrangement in this design is engineered to maximize brilliance from every angle. The intricate, branching gallery provides a delicate, nature-inspired aesthetic while maintaining excellent structural integrity, making it a perfect statement piece for high-end engagement proposals or exclusive fine jewelry collections.

Intricate Craftsmanship & Setting DetailsEvery curve and support in this CAD model has been meticulously sculpted with professional jewelry manufacturing and stone-setting in mind. The six-prong center setting and the angled side-stone seats are precisely calculated to ensure a secure hold while minimizing the visible metal, allowing the gemstones to take center stage. The open gallery beneath the stones is designed to let maximum light pass through the pavilion of the gems, ensuring extraordinary fire, brilliance, and scintillation.

3D Printing & Manufacturing Ready

The 3D mesh is a fully solid, closed, and watertight boolean union.

Zero naked edges, zero overlapping surfaces, and no non-manifold geometry.

Optimized for high-resolution DLP and SLA resin 3D printers (such as Formlabs, Asiga, Phrozen, and EnvisionTEC).

Proper shrinkage tolerances can be easily accommodated by scaling the model by your standard casting percentage prior to printing.

100% Customizable and Tailored to Your NeedsI understand that fine jewelry requires flexibility to meet specific client demands. This source file is highly adaptable and completely customizable.
