I forgot how to...

Hey guys quick question.

What item (and how do you) lets you put it in a chest, and it'll convert everything into diamonds, or as high as it can get to diamonds? I thought it was the philosopher stone but I'm not sure how to use it. Can somebody please explain.

PS:

I'm talking about it automatically doing it in a chest, not in a crafting bench.

One of these in an alchemy chest or alchemy bag.
