Labradorite – the schiller effect gets my motor running. I haven’t tried licking it. But probably should. ;)
Holy shit, labradorite is beautiful. We have a company here in town that does ‘granite’ countertops and I was always in love with it since my undergrad. I want countertops of it. However, the correct thing to say would be your favourite mineral is feldspar - no?
I mean, it’s sort of like saying selenite when it’s the gem quality gypsum. There’s nomenclature distinction, even if the chemical distinction is trivial.
Fair enough, just razzing anyhow.
Beryl! And chrysoberyl, and bertrandite, and helvine… (there is a theme here).
No, I do not lick these or other rocks, heh. The last time I was collecting halotrichite, there was enough dust kicked up I could taste it in the air, if that counts.
