Description

From the abandoned Valletta mine, well-known for exotic manganese arsenates, we have this excellent occurrence of the rare tourmalne bosiite, described in 2015 and found at just three world localities.

Bosiite from Valletta is manganese bearing, hence the deep wine-red color, with nice radiating groups of thin prismatic crystals on quartzite.
