How To Make A Diamond In Blender
Video How to make a diamond in a blenderYou need dispersion Dispersion is the multicolored bright spots you see in most transparent substances, caused by different colors (frequency of light) refracted at different angles (prism effect). Your reference image doesn’t have this, which makes it immediately noticeable as a CG. I would suggest starting with a reference like the following instead. Read: how to make a diamond in blender The first person to do it was probably Kirado who shared the node setup. Here’s the basic node setup – note how the IOR values differ:Going further…After doing some rendering with the above setup, I felt that the material still looked too dark, so I decided to try mixing it with a plain white Glass Shader in a way that wouldn’t affect the highlights. colorful. The Light Path Node’s “Is Camera Ray” output seems to work pretty well for this. What it does is take any areas where the RGB composite color hasn’t reached the camera and allow the Glass White (clear) color to shine right through those gaps. The diamond IOR is 2.4175 and the dispersion is 0.044. So using these values, as well as the actual diamond size, we can get something much more precise. Make sure to apply a scale (CtrlA) to your diamond object if you want the most accurate refraction possible.
Remember we are still “faking” by only setting three IOR values (for red/green/blue). But in practice, this turned out to be quite enough. For gems like diamonds, the cut determines how the light is reflected. Geometry plays an important role in the appearance of this material.

Luckily, creating an ideal diamond mesh can be done in Blender in no time. Just enable the Extra Objects (Mesh) add-on and it will be an option in your Add Mesh menu.
Now pressing ShiftA in the Viewport will give you new options:
In my example, I slightly chamfered my diamond, which allowed me to use Smooth Shading instead of Flat Shading. This eliminated the angular “CG look” and scattered the light in more directions, brightening the gem. However, user Thom Blair III noticed to me that diamonds are ground down to the molecular level, so a bevel is imprecise. Consider using Simple Subdivision instead.
Lighting Issues On an environmental map HDRI will provide a more diverse light palette for your scene, so consider using a palette if you want more realistic lighting. Adjust the color using the Hue/Saturation/Value button. In my case the sky was too blue, so I reduced the saturation.

Many thanks to the developers of Blender. (Okay, I mean keeping them less ridiculous.)
Setting Indirect Clamp to something like 10 also helps reduce fireflies.
CompositingIf you want to adjust the exact color of your gem or add bloom and streak effects, you can use the compositor to perfect the final strokes.
