Luc Yen minerals - the Hofmeister collection

Hi All,

Here you´ll find a small update with some gem minerals like spinel, ruby and tourmaline out of the collection of Prof. Dr. Wolfgang Hofmeister, former head of the Institute of Geosciences at the Gutenberg University 
in Mainz. Specimens from Luc Yen are not really abundant so take your chance to pick some nice examples.

Wolfgang Hofmeister brought these specimens from his numerous trips to gem stone occurrences worldwide and has published on the Luc Yen occurences as well. See for instance: Hauzenberger, Ch.A., Walter, F., Hofmeister, W., Phan Tien, D. & Kienzl, N. (2005): Mineralogical, petrological and crystallographic investigations of two amphiboles from ruby and spinel bearing marbles, Luc Yen, Province Yen Bai, Vietnam. In: Hofmeister, W. et al. (ed): Proceedings of the third international workshop on gem-materials and modern analytical methods. Hanoi, Vietnam. 3-8.

If you have any questions please feel free to contact me (as usual).

Enjoy! Cheers, Roger
