AUSTRALIA and beyond - We need to assemble again for #Putnisite! This amazing structure needs your support in today's #MinCup26 battle. For shear density and novelty in its strange/wonderful crystal structure it should get your vote over #Julienite
Image representing the crystal structure of putnisite - here red spheres represent oxygen atoms, light blue spheres/polygons represent calcium atoms, dark blue spheres/polygons represent silicon atoms, brown spheres/polygons represent carbon atoms, green spheres/polygons represent strontium atoms. There is also some chromium hiding in the structure that is in part represented by a yellow triangle. The representation is drawn in VESTA from entry #20044 in the American mineralogist database
Image representing the crystal structure of julienite - here red spheres represent oxygen atoms, dark yellow spheres/polygons represent sodium atoms, dark blue spheres/polygons represent cobalt atoms, yellow spheres represent sulfur atoms, brown spheres represent carbon atoms and light blue spheres represent nitrogen atoms. The structure is viewed down its c axis and shows that there are sodium/water(oxygen) units surrounded by cobalt complexes with nitrogen, carbon and sulfur attached. The representation is drawn in VESTA from entry #9760 in the American mineralogist database

Split photo of tiny grape-jello purple cubical crystals with a rough surface. The crystals are poking out of a massive rough rock with areas of fuzzy green and broad purple, all with a grainy coating of white as though it were rubbed with flour. The other photo is saturated cobalt blue needle-line crystals in a narrow fan sparkly and rough on a smooth creamy background

A tough decision in #MinCup26 today, as they're both so pretty. Do you go Julienite with the tragic backstory, or Putnisite, discovered on Polar Bear Peninsula (because Australia is famed for its polar bears) and is "utterly unrelated to any known mineral or synthetic compound"? I'm team #Putnisite

And when I reach Australia I'll go and search for gold And maybe find some putnisite Or so I have been told And when I've spotted purple I'll be sure to take you there 'Cause it's found no place but what looks from space Like Australia's Polar Bear #MinCup26 #putnisite #parody

Widgiemooltha is a 1897 historic town in Western Australia’s goldfields that arose during the gold rush, & was named the aboriginal name for a nearby hill. This pretty purple putnisite crystal was found there. This mineral has a completely unique chemical structure found nowhere else in nature.
This tiny purple putnisite crystal is from the Armstrong Ni Mine, Widgiemooltha, Coolgardie Shire, Western Australia, Australia. It is unique in chemistry and nature, and found nowhere else. From Mindat: https://www.mindat.org/photo-543393.html

Revenge for calcite! Vote #putnisite! Long blue minerals are so #MinCup25, and at least #kyanite could handle pressure. Julienite knows only death—and not even a cool goth way. #MinCup26 can do better.
