Creating a realistic crystal

I am trying to import a test object that I made in unity. It is a simple glass material that refracts light and has a displacement texture (to give it imperfections) and I wanted to know if there was a way I could import this into unity (or at least create something similar). I have a picture of the objects setup below (the red object is a test object that I put behind the crystal to make sure that it was refracting light correctly).[34872-screenshot+2014-11-08+17.39.18.png|34872]

I assume you meant to write that you created this object in Blender, not Unity.

You’ll have to create a Unity shader that replicates the functionality of the Blender shader shown. These are good places to start (both free)
