Or, it's just another spin of the anthropomorphism bias we have. If anyone found those mineral what, 50 years ago? or let's say 150 to predate every quantum theory possibility... well, they would have been just nice and weird crystals with 0 importance, just because we didn't know about their properties.

But now they have suddenly a meaning so hey, maybe it's somebody like us, smart as us, that created them many eons ago to harness quantum capabilities back in the day.

They were in fact discovered 54 years ago. The quantum properties weren’t recognized until 2012.
