'HERMANOV SPHERE' 

(PHLOGOPITE AND ANTHOPHYLLITE)

 

Heřmanov, Vysočina Region, Czech Republic

  

A very good example of what is known as a ‘Hermanov sphere’.

 

It consists of a core of phlogopite mica crystals with a shell of radiating anthophyllite crystals. These mineral curiosities are unique to this location.

 

This is a good example from an old university collection.
