One day at work, I found out a work friend actually believed the whole "crystal energy" thing.
Since she was the first person I had ever met who actually admitted to that, I wanted to know more about what her specific beliefs about them were.
At first she was super bubbly about it, on par with her personality. But then as I asked a couple common sense questions about why science doesnt find anything measurable, and first she got hostile and mad that I would dare question another person's beliefs, but when I explained I was genuinely curious and had no interest in changing her beliefs she just kind of broke down because nobody ever takes her seriously or believes her about her "personal healing journey"
The way I see it, it's for adults who like pretty rocks, but can't come to terms with the fact that they like something "childish" (because for some reason a lot of adults call a rock collection cringe or childish or dumb, but clearly they've never met a geologist) so instead of having a pretty rock and mineral collection, they have "healing crystals", and eventually it just becomes kind of like part of their identity the way a religion is.
I will however, 100% giggle at their expense with my wife, later. Because anyone who buys $50 polished selenite ~~drink coaster~~ "charging plate", and a $200 brass pyramid to "recharge" their $50 "healing quartz wand" while refusing to listen to real science deserves to be giggled at.
