Is there anything that can stop honey from crystallizing?

I have a jar of raw, unprocessed honey that I like to use for my tea. This is the second jar I’ve filled from a local farmer’s market, and for some reason this batch is crystallizing a lot faster than the first one. It’s not because it’s cold – it’s actually unseasonably warm where I live, so I can’t figure out why.

So now, I just want to know if it’s possible to stop the progression or if there’s a way to reverse it?
