Description

The Mambertiite is an extremely rare mineral with a close structural relationship with Gelosaite. It was only found in its type loclity. Only two samples of this mineral of Mo and Bi have been found. I picked up these small fragments when I broke the sample (the olotype) in two parts and as they were not necessary for the analysis I kept them in my collection until today. I personally collected the sample in the old mine's dump. It is accompanied by a label of my collection. In the small capsule are contained in addition to the two fragments of Mambertiite also small fragments of quartz and molybdenite. In the photos I highlighted with a red arrow one of the points where crystallinity is most valuable.
