Found in a mine in Mexico. Now lost again as the mine got flooded.

If not the best, certainly one of the weirdest! I hate to ask, but can we assume they are real, rather than AI'd ??

Definitely real, cave of crystals in Mexico. Discovered years ago though, not sure why the sudden interest with this post though 🤔

No idea how accurate this is, but it was found in April 2000 and reflooded in 2015:

There were a couple of TV film documentaries (Nat Geo?) released about 15(?) years ago.

I think I found the first one on YouTube but only in French.

Here's a link to the second one Naica 2 - Beyond the Crystal Cave in English.

And another adventure type program Angry Planet
Skip to about 7mins to see the start of the journey underground in the mine and then the cave.

I thought the Bristly Table in Easter Cave WA was pretty spectacular! And the cave is young by geological standards as it has formed in what are is essentially limestone formed by sand dunes from the Pleistocene.
