Team #cuprite , le quartz c'est une fête commerciale désolée :)

Things that make me laugh:
Every time #Quartz has been in the #MinCup finals, it’s been against a mineral with the composition X₂O.

This is particularly funny as ice and #Cuprite are the only two minerals with this composition, & ice took #MinCup19.

Win some, lose some?
Or history repeats?

Quartz? Basic as hell. #Cuprite is where it's at.

Haha, if #cuprite loses, that's the angle I'm taking. At least I don't have to hear quartz mentioned for a loooooog time.

#MinCup26 Vote for the shiniest, most brilliant, and #TTRPG diciest mineral in all the lands! Vote #cuprite!

Silicon dioxide? No thanks.

Team #cuprite since I love an underdog

Vote for the rock in your heart! #Cuprite for me. Best mineral wins! #MinCup26

#MinCup26 FINALS!!!
We have a pair of geometric beauties as deep red #Cuprite is against versatile #Quartz.

Despite the difficult choice I will keep my position from the QF: #cuprite it is for me.
While not good as jewellery its high IOR does it for me.

Plus we need to appease our mechanical overlords 😉 and cuprite is easy to obtain copper from!

Don't be swayed by #Cuprite's pretty looks; #Halite can be just as beautiful and is essential to life. Besides, imagine chips, crisps, or indeed any meal without salt. You've got just under 3 and a half hours to vote: don't delay!
#MinCup26

Gotta go for #cuprite.

The complex crystal shapes look so mesmerizing.

Plus it forms cubes/octahedra so it can look like dice, granted #halite can too! But it can become malachite so turquoise color dice :)

How are we on #MinCup26 semi-finals ALREADY? I voted #Halite, but I've also been team #Cuprite up to this point and won't be sad about either outcome.

We're at the point where only bad bitches remain and there are no wrong answers...but also #Cuprite is the MORE correct answer!

#Cuprite may be the “flashy” colourful mineral, but I am #TeamHalite because it is an essential mineral! I live on the edge of Cheshire, and #Halite has been an important part of local industry for millennia! If you vote #Halite I will go to Nantwich tomorrow and show you proof!

I am truly torn here. #Halite is just so good and useful and not thought about as much as it deserves... But #cuprite is so pretty and interesting.

Semi final #MinCup26 match up between #Cuprite and #Halite - I'm now fully behind the magnetic #Cuprite - and have dug out that neutron diffraction discovered it has nearly ZERO thermal expansion from 200-300 K link.springer.com/article/10.1... WEIRD!

Let's see #Cuprite in #MinCup26 finals! Jauch and Reehuis used γ-ray diffraction to revisit how electrons are arranged in Cu₂O, finding incomplete ionization of Cu and O but no Cu–Cu charge build-up to support covalent bonding. Reported in @actacrystb.iucr.org: journals.iucr.org/paper?S20525...

#Halite!! Though I just purchased this lovely little specimen of #Cuprite #MinCup26
