refraction and caustics in cycles
Remove your Solidify modifier.
Or just click that little camera icon to hide it in the render.
It's disabled in the viewport, so you don't see it, but when you render, it's still activated.

Give your object a Subdivision Surface modifier.
Then turn on Adaptive Subdivision. (Make sure you're using the Experimental feature set in Cycles.)
Don't forget to have a Displacement node connected ...
