12-18. Piypite #2.

Quite a complex architecture to build a tiny mineral glass blade!

12-17. Piypite #1.

This is what it takes for nature to create a mineral grass blade!

Piypate is a very unusual mineral that grows in tiny green crystal blades bunch. It was first found in 1982 in the confine of Russia by the sea of Bering, very close to China and Japan. Some Piypite has also been found near Napoli, Italy, since. It’s named after Boris Ivanovich Piyp, vulcanologist, and past director of the Russian Far Eastern Institute of Volcanology.

This tetragonal-pyramidal mineral contains copper, oxygen, potassium, and sulfur. I mention its chemical composition because last week, green atoms (CI-Chlorine) were prevalent in the Vanadinite crystal and gave us a warm, red mineral. This week red atoms (O- Oxygen) create a green crystal. Nature has a way to handle color that we still have a lot to learn from!



12-16. Vanadinite #7.

A green (CI) Chlorine molecule at the center of the vanadinite very dynamic symmetry!

How does that mineral come in such warm and pleasant red-ochre? Colorist need to go back to the drawing board!

12-14. Vanadinite #5.

Tiling may seem like a very abstract challenge for some. Nature knows different. This is a front view of a Vanadinite crystal unit cell. A stable and sturdy prismatic hexagonal shell is all that was needed to contain this busy pack of unruly atoms.

It makes for quite an uncommon and beautiful mineral too!

12-13. Vanadinite #4.

A very playful & Christmassy crystal of Vanadinite. Unit structure, atoms, even the Van der Waal force curtain between atoms in on! Bold maybe, but nature knows best!
