From a resource Sokolova and Hawthorne: crystal structure of a scapolite from Monte Somma, Italy.

Even the local crystals reflect on the elegance of the Italian lifestyle!

A crack in the wall!

The scapolite geometry is very intense if anything. Inspiration sometimes just has to follow what shapes dictate.

A mad architect’s design? No, just the inside of a scapolite unit cell.

I would not recommend it for a building – but in nature – it seems to works. Scapolite minerals grow in column-like shapes and their hardness is enough to sustain the pressure of time.

Scapolite – a strange and very busy mineral!

Hard to capture, it comes in many colors. Its structure leads to an odd and complex geometry. It will be the mineral of week #22 of this 52 weeks tour of the geometry of Nature.

The scapolite group includes crystals such as meionite, marialite, and silvialite. The name comes from the Greek skapos (shaft) because of the stumpy nature of its crystals. Colorless in its pure form, inclusions give it a bluish gray, greenish yellow, pink, violet, golden yellow color.

It belongs to the tetragonal system – three axes at right angles, two of them equal.

The best scapolites have been found in Madagascar, Myanmar, Tanzania, Tajikistan, and Peru.
