How to render a jewelry 3D model?

To render a jewelry 3D model, use software like Blender or KeyShot to apply realistic materials (metals, gemstones) and lighting, emphasizing facets and shine. Start with smooth geometry—clean surfaces are critical for accurate reflections. Assign materials: metallic shaders for metals (add subtle scratch maps) and refractive shaders for gems (match properties like diamond refraction). Use soft lights or HDRI maps to highlight sparkles and avoid harsh shadows. Adjust render settings (resolution, anti-aliasing) before exporting. New to rendering? Use KeyShot’s jewelry presets—they simplify material and lighting setup for quick, realistic results.
