There is a lot packed in one mineral all of which are rare tin minerals. Tin minerals such as these, which were tested, are very rare. It carries a University of Salzburg label as seen in the provenance tab. My guess is that it originated with the well-know mineralogist, Werner Paar. I don't think any of the minerals can be easily discerned with the eye. However the microprobe disc is proof enough for identification. The specimen is sawed on one side. It is very heavy and is dark goldish metallic.
