If you find yourself intrigued by calcite crystallography, I strongly recommend browsing Goldschmidt’s Atlas Der Krystallformen, which has 150 pages of this.

When evaluating rocks for personal use, it’s not just about shape (although that better be gratifying).
Texture, strength, hardness, solubility (in water & acid) are all important considerations, occasionally along with more obscure characteristics like smell or stability under surface conditions.

My vote is for #adamite because of the adamite bat.
The bat is largely mummified but adamite has started to replace around its face - fluorescent light highlights the adamite.
Found by John Seibel, late 1980s at the Gold Hill Mine, Utah, collection of Mark Mitterman.

One of the coolest things about #Goethite is that it frequently replaces other minerals taking on their shapes as a psuedomorph. Below is Goethite after Marcasite, Goethite after Selenite, Goethite after Pyrite iron cross twins, & a lovely gothy Goethite crystal spray just for fun. #MinCup23 ⚒️

This round is going to break my heart because #goethite is the only mineral in the bracket I REALLY like, and it’s going to get beat out by a mineral I can’t see.
Vote #goethite to make me wrong, and thus happy. 🥺

Crocoite has an unusually frequent tendency to grow into such crystals so extremely hoppered that the crystals are HOLLOW.

This is what happens when stibnite “rusts.”
I had to unpack a backpack full of rocks for the TSA over this specimen once, and the man was so, so very disappointed when we opened the box and I’m still laughing about it.

Want an early start to #MinCup23? Read Howard Lee’s great article about U-Pb dating of zircons, and use of magnetic data to find out how surprisingly fast the Pilbara Craton was moving 2.7 billion-years ago. This incredible usefulness is why zircon is called the Time Lord. Expect more Time Lord soon

One of my favorite things, for being so plain but so incredibly cool: the oldest mineral yet found.
Jack Hills zircons have been dated to ~4.4 billion years ago. They were formed during the Hadean (all of earth was more-or-less molten), then cycled into sedimentary grains. #MinCup #TeamZircon

Oh, also, cinnabar isn’t toxic.
Containing an element that is harmful does not make a mineral harmful. This is a matter of bioavailability - whether the body can absorb any of the harmful element. Largely this boils down to solubility, and cinnabar isn’t very soluble. #MinCup23
