Description

Specimens from Vietnam are not really abundant. This very nice spinel crystal aggregate comes out of the collection of german mineralogist and former head of the Institute of Geosciences of the Mainz Gutenberg University Prof. Dr. D. Sc. h.c. Wolfgang Hofmeister. The pale pinkish (and partly sort of iron stained brownish) crystals are twinned and nicely show the re-entrant angles. Nice LW-UV fluorescence also!
