Yo! This is Fluf59001 here. I'm going to talk about a theory

What happens to a gem when chipped?

So, we seen a chipped gem ONCE (I think). 

So the Ice Monster's gem looks chipped (Like a piece broken off)

And so see that she... Broke apart..? She was defeated by Garnet and she literally broke apart, and her gem floated..? ERROR OR CLUE?!

I have a theory that the Ice Monster's gem was possessing some ice somehow. She has a light blue body, looking like ice and breaking when damaged (Like ice). She lived in a frozen cavern, (Ice everywhere and cold enough for the ice to not melt).

So what do you guys think?
