I gotta vote on this. I was gonna see if I could find my #dioptase specimen just for the show off potential (it's not big but it is pretty), but eh.

I don't think I'm gonna get science-y on this matchup, bc come on, I know there's literal geologists and *chemical geologists* at that who weigh in on this every year who know it all better. Anyway I'm not over how guano is a key part of #ammineite and I don't think I ever will be, so 🤣. #MinCup24

#Ammineite is amazing! It comes from #guano, which is also amazing! See thread 👇 to learn why #BatAndBirdPoop was a critical natural resource.

Sending #Ammineite some love in #MinCup24 ⚒️🧪

It's a amazingly rare mineral requiring a combination of copper mineralisation and nesting birds. It demonstrates the efforts the Universe goes to create fascinating complexity.

I'm also intrigued by the notation that somewhere out there this mineral may have formed with dinosaur poop... 🦕

Not only was #ammineite recently discovered, it's only been present for a short part of Earth history; it needs copper and guano in dry areas.

#ammineite vs #perovskite... absolutely just for shits and giggles I'm team ammineite.

(Absolutely none of you can tell me that funny chaos doesn't count. Are we really living as adults if implied poop jokes aren't hilarious?) #MinCup23

#MinCup23 Round 2 Match 6: Which delights you more: the unique incorporation of guano-born #Ammineite, or the technological potential of #Perovskite’s unusual crystalline structure?
