BigLeagueChewite with flakes of poprocksium.
Commonly occurring in the spring, largely in little league dugouts; not naturally-occurring or native, this is considered an invasive mineral deposit, spread by juvenile local fauna.
Lol at calling children "fauna".
My guess is pink cobaltoan calcite with malachite.
I used google lens & google image search.
Here's a similar image:
Thanks for the reply! It's not Calcite, but you sent me down the right path! Figured the green was malachite, and after some some tests, I'm pretty confident it is.
Your picture does have a striking resemblance, but the crystal structure in mine seemed off for Calcite. Figured you were likely right with the cobalt, that's what is causing the pink color. It has a hardness of 3.5 - 4 (penny does not scratch, Fluorite does), so that rules out Calcite. It also did not react to lemon juice, and it streaks white.
My current conclusion is that it's Cobaltoan Dolomite. It can look very similar to the Calcite. I'm still bothered, because I don't think that is the name it was sold to me as. Might take it with me next time I visit the shop (I think) I bought it from, and see what she thinks it is.
