Trimerite

  

This specimen has a druse of gemmy crystals of trimerite to 4 mm in length. This specimen also appears to have either tilasite or manganberzeliite as indicated by the reaction under SW UV light. The best trimerite specimens, of which this specimen is, were found in the Hindenburg workings of the mine.
