I’m totally amused how #quartz is catering the pity vote. All of #MinCup was created to make it feel special, yet every year other minerals win. Poor quartz.
Meanwhile #calcite is both fun & a climate indicator.

#Calcite is a mineral with neat optical properties, fizzes with acid, flags your attention when you stumble on to an ancient sea floor in the mountains, was a critical plot point for the premiere of #Stargate #SGU, and tracks climate.
But I lost a bet.
Whoo #quartz.

So. #Quartz.
It’s most of Earth’s crust. If you’re only learning one mineral, quartz is a good default guess.
I can’t help with ID more than”uh, it’s hard?” unless it happens to be a pointy crystal, but I’ve never found those in the wild. It’s the white bits of granite.

I had exactly 30min entry-to-exit to explore @hmns.
I’d heard they have a solid collection of trilobites & the massive cut blue sapphire Siren of Serendip is a special exhibit.

#Crocoite: Shiny red-orange spiketastic lead chromate.
Despite being named for colour-matching saffron, lead makes it firmly “Do Not Lick.”
This particular spikefren is from Adelaide Mine, Tasmania, sticking with “everything cute in Australia can secretly kill you” theme.

#Fluorite: a honkin’ massive cube of calcium fluorite with that particular dull-waxy translucence I wanna pet so bad.
No UV light to see if it’d fluoresce pretty colours for me.
From Nikolaevskiy Mine in Russia where hot sulfide solutions crystallized in limestone caverns.
