On this #MineralMonday I offer you my latest green aquisitions (and one impostor)

In order: #Demantoid, (Oxy-) #VanadiumDravite, #Arsenopyrite, #Peridot!

Any other #MinCup26 match, I'd vote #arsenopyrite all the way. BUT this year I visited the #Wieliczka Salt Mines in Poland. And we were explicitly told that it was "okay to lick the walls" if we wanted. So #halite all the way this #MinCup.

Yes, these sculptures are made of salt.

Cannot believe that people are voting for boring old salt instead of stinky poison gravel

#Arsenopyrite

#MinCup26

#Arsenopyrite because poison! But so is #Halite in the right dose!

#MinCup26

I was nearly swayed by #arsenopyrite in today's #MinCup26 match, I do like the wavey AsS arms sticking out of the iron units. But for a crystallographer #halite is the ultimate classic, literally the first crystal structure ever determined (by the Braggs) so that gets my vote today

#MinCup26 Round 1 Match 13
It's a match between a mineral you want to be cautious breathing near and one you eat every day as arsenic-rich #arsenopyrite is against table salt #halite.
