Notes / Further information
An original Breithaupt specimen (labelled FR) was recently discovered in the Mineralogical Collection of the TU Bergakademie Freiberg under inventory number 21519. The previously mentioned #21359 (e.g. Anthony et al., 2000) is incorrect, as it refers to another piece from Hrbek, which was later added to the collections by Friedrich Kolbeck (1928). |
