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 for such a small crystal – almost like little gems within its crystal structure.
Chiolite will be the mineral of week 37 of this short tour of the Geometry of Nature. Maybe it will reveal some other hidden surprises art and art lovers can be inspired from.
