Second, the more information on the screen, the more I have an urge to discard most of the peripheral objects to focus and capture the essence of the message.
I’m not sure I did it successfully, but it led me to quite a week of practice of minimalism style. Still surprised after 35 weeks in this Geometry of Nature projects! Thanks for the journey little crystal.
09-10. Chiolite #1.
Some say it’s a useless mineral. The industry has not found yet a way to exploit it; Gemologists finds it too difficult to cut. Maybe art can redeem chiolite, this tiny, rare, snow-like mineral first identified in the Ilmen Mountains, Russia in 1846.
It belongs to the tetragonal group and is of symmetry P 4/mnc. The VESTA 3D model shows some beautifully well-formed octahedra

Maybe its cognac or chartreuse yellowish green color had something to do with it – the story doesn’t say. Renamed titanite again in 1982, both names are still in use.
Titanite is a small monoclinic crystal of symmetry P2 and of medium hardness. The industry uses it in pigments while gemologists praise its exceptional dispersive power.
This is how the Hollabaugh and Foita resource from the Grisons, Switzerland, appears in the VESTA modeling program – quite an imposing crystal!

I’ve never found so many people associated with one single resource , but I’m going to credit them all anyway, they deserve it somehow: Hawthorne F C, Groat L.

09-24. Atheneite #1.
The making of a moiré!
23 atoms, 0 bonds, 0 polyhedra – that’s all this little crystal of Atheneite study of L. Bindifrom Florence U. has to offer for week #39 of this short tour of Geometry of Nature.
Atheneite is a rare mineral associated with palladium-gold deposits. It is so small, it was only first identified in Brazil in 1972. Today, tiny samples can be seen at the Natural History Museum in London.
Atheneite is named after the Greek goddess Pallas Athena, not because it could use all the protection and safety the goddess is supposed to bring, but because of its palladium content. Its structure is hexagonal and its symmetry belongs to the group P6.
In this visualization, I enlarged some of the atoms wireframe to create a moiré effect. I left the beautiful symmetrical display untouched and put the whole over a marble-like pixelated background and a fractal frame.
Interesting coincidence, in 1993, David Bowie wrote a song called Pallas Athena, a short sequence of superposed word & sounds in a very dark, bluish-purple-gray environment – the color of the mineral itself. The story doesn’t say if he was inspired by the Atheineite
