Description

A small but nice greasy lustrous aggregate of demantoid crystals from Sondrio with some whiteish cover of fibrous asbestos. From a small lot in a box labeled to be from Sferlun, Campo Franscia.

I am not the Malenco/Lanterna valley expert so i don´t know if it comes from former Sferlun mine or Campo Franscia quarries.

Nevertheless a nice european classic.
