Also, use diffraction to get even more astounding looks (note: takes more computing resources)
How do I use Defraction and where can I find it in blender? Watching the link now! Thanks!
Sorry, my bad, that would be Dispersion.

Since the examples given there are limited to (optical) glasses, we also have a small list at the bottom of the following LuxCore-Wiki article:

For artistic purposes, you can try to exaggerate the "Dispersion" value. There is a gif of a diamond in the article to show the impact.
