Shungite supposedly has some interesting properties, like healing and electromagnetic resistance

Far stretch, but I think I remember a bit now, it was the aesthethic of the second international tournament, the aesthetic was silver/stone and cyan IIRC

Tigers eye was my favorite as a kid. Feels a bit weird having grown up and realized all the shops I used to buy my rocks from were selling them because of 'healing energy' hippy shit, I just thought they looked cool.
Pic related is my current favorite rock though, packs a real punch
(46.78 KB 500x540 cguucrP8w1ragjj861.jpg)
The structure of rocks can actually have many different effects
Crystals are piezo electric, if one hits a crystal it can grow a tiny bit and emit an electric pulse that effect is used in tiny speakers/microphones
Crystals are also used as oscillators for clocks
But yeah they look cool
(269.79 KB 1200x1200 neodymium-magnets.jpg)
Magnets also work because of their structure, they are polarized in such a way that their atoms align the electrons synchronously. A moving electric current always makes a magnetic field, in the magnets the atoms electrons make like a current within the material structure itself
(12.29 KB 338x201 c12a66193c8f.jpg)
Another really interesting thing is that bones are piezo electric

>bones are piezo electric
that is interesting tbh.
a) how does that happen
b) what effect might it have on living ppl
(106.31 KB 500x667 ga07kgCHHO1ql7t7zi1y.jpg)
Well, bones grow and have a structure, minerals go into building them so I guess it makes sense

I assume most of these specimens are far too fragile or otherwise sensitive to be on public display. Are they kept locked away in vaults or something?
I doubt it, maybe some of them are, but the hardness varies
I would think most of them are from private collections or if in public displays and fragile, that they're then stored in glass cases or monitored and guarded closely (like in the case of the crystal skulls maybe)
Crystals can sometimes chip or shatter but if you try to saw one, you'll find that its immensly difficult, even with a ceramic saw

A lot of these in the thread are some kind of quartz, fluorite, bismuth and tumbled stones of various types. Quartz, fluorite and tumbled stones I have a couple of in my collection and they aren't fragile at all. If you put them in a box they might chip or scrape a little but that's about it. Bismuth however, is really fucking fragile. When I first got mine it snapped in half just from handling it. I wasn't even throwing it around or anything like that. I was looking at it and it snapped in two.
(207.07 KB 993x594 theurgy-stones-to-purposes.png)
That's interesting, I've never handled or seen Bismuth in real life, but I read a lot about it
I found this interesting text about different kind of stones being used for different effects
I know there are lodestones and they're natural magnets. Quartz and some other crystals are used for clocks in computing which computers wouldn't work without
