I'm still salty that #Cupirte beat #Orpiment in the first round of #MinCup26 - so today's vote is for #Andalusite out of spite. Plus it has got a more interesting crystal structure, so there's that too.
Image representing the crystal structure of Cuprite - here red spheres represent oxygen atoms, and blue spheres represent copper atoms. The structure has been expanded over a,b and c axes to show off quite how boring it actually is. Just copper bonding to oxygen, not even making up a polygon. Literally without the magnetic properties of this mineral has it would be a right snooze-fest. The representation is drawn in VESTA from entry #7351 in the American mineral database Image representing the crystal structure of andalusite- here red spheres represent oxygen atoms, light blue spheres/polygons represent aluminium atoms and dark blue spheres/polygons represent silicon atoms. The representation is drawn in VESTA from entry #728 in the American mineralogist database
