General DescriptionHigh-quality 3D model of a classic and timeless solitaire engagement ring. The design features an elegant cushion-cut center stone secured by a sturdy 4-prong setting, seamlessly integrated into a smooth, comfortable half-round band profile.

This model was created with technical precision and realistic proportions, specifically designed for real jewelry manufacturing. It is optimized for resin 3D printing (SLA/DLP) and subsequent investment casting in precious metals.

Technical Specifications & DimensionsThe dimensions were carefully calculated to ensure both durability after polishing and comfort for everyday wear:

Ring Size: Inner diameter of 16.51 mm (Equivalent to US Size 6).

Band Width: 2.20 mm (measured at the bottom/base of the shank).

Model Features3D Print Ready: Watertight mesh, no open edges, and free of geometry errors. Ready to be imported into your 3D printing slicer.

Functional Design: The prongs feature sufficient extra material (allowance) for the jeweler/setter to securely fix the stone during the bench work process.

Applications: Ideal for casting in Gold (Yellow, White, or Rose), Platinum, or 925 Sterling Silver. It also serves as an excellent, highly-detailed asset for photorealistic rendering projects.
