Today’s distraction:
The winner of this match will face #Magnetite for the finals with a shot at the #MinCup2020 crown. Both are beautiful & bizarre with odd properties and a lot of charm.

Both are Safe But Boring to lick. They even have similar texture (smooth). As far as your tongue in concerned, it’s a wash. You’ll need different criteria to pick your fav.
(One #MinCup we’ll have either a Fun To Lick or a Do Not Lick finalist and I will be overjoyed)

#Fluorite is a basic calcium fluoride (CaF2), which didn’t give me headaches when memorizing composition for mineralogy exams.
Amusingly, the element is named for the mineral, not the other way around. Same for fluorescence: the effect named for the rock’s distinctive property.

Both today’s #MinCup2020 contestants are Very Good Rocks.
#Kyanite: so finicky it’ll change structure to different minerals depending on temperature & pressure
#Corundum: a hard (Mohs 9!) workhorse with a shiny side when contaminated (aka, ruby & sapphire).

Both minerals seem very suitable as 2020 Champions.
Who among us isn’t a bit blue, spiked, & highly responsive to pressure? Congrats, #Kyanite is kin.
Yet we’re also surviving day after day without being ground down, and still finding moments of sheer beauty. That’s #Corundum.

I voted #Kyanite because I love unmistakable-to-ID minerals and appreciate when they shout their stories in case I’m being oblivious, but it could’ve gone either way.
