Everyone likes showing photos of clear quartz, but I love #quartz because it can be purple (and other colors)! Just look at this amethyst! Stibnite is cool looking, but it isn’t this lovely color. #MinCup23 https://www.mineralcup.org/2023/campaigns/campaigns/round-2-match-2

Kaolinite gets my vote today for #MinCup23. It’s used to make paper, ceramics, paint, and lots of other things. In some places in the US you can go into a convenience store and buy a bag to help with tummy troubles. Go team anti-diarrheal!
Providence Canyon in Lumpkin, GA (USA) was formed by bad farming practices in the 1800s. It’s 150 feet deep and one of the exposed formations contains lenses of kaolin. It was one of my favorite geology field trips!
Easy vote for me today. My choice is the absolutely gorgeous pink #rhodochrosite which I fell in love with as soon as I saw samples from the Sweet Home Mine in Colorado. #MinCup23 https://www.mineralcup.org/2023/campaigns/round-1-match-16

Tough choice today for #MinCup23 Both are gorgeous and no matter which one wins, it’s a blue mineral! My choice for today is trusty index mineral #kyanite which always gives me a clue to how a rock was formed. And it has different hardness depending on which direction you scratch it (insert your own naughty joke about hardness here). https://www.mineralcup.org/2023/campaigns/round-1-match-15

I’m going with #Neptunite for today’s #MinCup23 matchup. It has beautiful crystals, is friends with Benitoite, and it’s named after the Roman god of the sea because of its close association with aegerine (named after the Norse god of the sea) at its type locality.

I’m choosing #dioptase for today’s #MinCup23 match. I just love its pretty blue-green color and it gets bonus points for being a copper mineral.
I also found a piece in my car once. Who knows where it came from or who left it, but that little chunk of dioptase has become one of my favorite minerals to display.
