12-23. Piypite #07
A strange but colorful and lively week! Piypite may be a rare and tiny mineral, its geometry is unexpectedly inspiring. All the more that I used only two resources in a rotation for these last seven days.
Credit should go to Effenberger & Zemann, Kahlenberg, Piotrowski & Giester, and of course to the program VESTA for bringing life to such interesting data.
