I thought the whole 'petrified wood' thing at the state park gift shop was a total tourist trap scam. Then I saw the cross-section under a loupe.
It was at the Petrified Forest in Arizona. I bought a small slice on a keychain for like five bucks, fully expecting it to be dyed plastic. But I had my 10x loupe in my bag, and under magnification, you could see the actual cell structure of the wood, perfectly replaced by silica. The rings, the grain, everything. It was a rock, but it was a tree. Blew my mind. What's something basic in geology that actually stunned you when you saw the details up close?

......and that's exactly why I don't buy rocks from gift shops anymore unless I can look at them through a lens first. I once bought a "geode" from a fair that was just a painted plaster ball with some quartz glued inside. My buddy still won't let me live it down, calls me "the guy who bought a fake rock." But honestly, seeing real petrified wood up close like that is something else. The cell structure part gets me too, like the tree is still there but it's stone now. It's the kind of thing that makes you feel small in a good way.
