Robo Cop 2: What is that crystal thingie?

In Robocop 2, there’s a scene where he goes to find Kane in the sludge factory.

Right after his car blows up, he walks in a sort of shrine area.
It has the bones of Elvis and something about Mother Theresa.
Right after he sees the Elvis bones, he walks past some sort of glass-crystal thing. It’s about as tall as he is.
The camera sort of lingers on it.

What on earth is it??
