I am trying to make a scene of diamond animation. but i can't figure out how to make it realistic. i used glass material and modify IOR. but i can't make a real diamond material. please show me the way how to make it.

thanks-

Adding more Bevel to edges maybe can make better your result , Also I think using Glass diffraction shader can help you too , check this topic :

And you need to have much better background to reflect than what you have now.

And you need a few key point lights that are very bright to make the caustics pop. Not your standard even scene lighting.

Think MR16 ceiling lights. Small intense source. Every jewelry shop has these lights for a reason.

Maybe if the poster put up a scene file we could have a shared experience on how to light and render diamonds !

thanks for replying. Feeling more comfortable now. actually i want much more realistic shader/ material for diamond. but i can't achieve it. i have tried another process with material shader builder with refractive light. but can't get it.

thanks again for your valuable opinion. i am posting project file(*.hipnc)
