Pack of glass shaders with various dispersion algorithms and shades + some plastic materials.
Better use cycles but who am I to restrict you doing what You want :D
Uses HDRI from polyhaven.com(packed in rar)
Play with nodes parameters and maybe You'll get even more interesting results!
Good luck ladies and gentlemen.

Ever Yours,
Alexandr.
