How to Make Realistic Diamonds in Blender (Full Process)

Learn how to render realistic diamonds and gemstones in Blender — materials, lighting, render settings and compositing. In this video I walk through my full process for rendering a diamond ring: how to set up caustics so the stones sit properly in the scene, building the shader with the right IOR and dispersion for each type of gem, and a three-point lighting setup made specifically for gemstones. I also show the part most tutorials skip — how to light metal and gems separately using collections and holdout, then combine both passes in the compositor. Plus the glare setup that gives every highlight a real sparkle. ⏱️ TIMESTAMPS 0:00 The result 0:13 The scene 0:37 Materials and Refraction 1:17 IOR and Chromatic Dispersion 2:58 HDRI as a base 3:47 Render settings & caustics 4:50 Three-point lighting for gems 5:50 Lighting metal separately with holdout 7:38 Compositing both passes 8:15 Glare — the finishing touch 8:40 Recap 🔗 LINKS Free project files → [https://motiondaniel01.gumroad.com/l/...] Studio → radiantframe.studio Instagram → instagram.com/motiondaniel 🛠️ Blender · Cycles #b3d #blender #blendertutorial #3djewelry #diamondrender #jewelryrendering #cycles #caustics #productvisualization #3dart
