Bounjour,
sorry i not speak French, but this forum is very interesting.... Sorry i`ll write in English, if i use a translator from German to French the results are not very good to understand..
I´m living in Germany not very far avay of the Lorraine (Dept. 57) and so i have some minerals from there to show you, too. The last posting minerals are also very nice, special the Quartzes from Sierck-les-Bains and Contz-les-Bains. I also have some speciems from there.. but not so good as the findings 20 - 30 years ago. Do you know how large the biggest Quartzes are???

So, here my pics:
first a about 3 cm large clear Quartz with phantoms of Chlorite/hematite inside from the old carriere of Sierck-les-Bains
then a single small Quartz xl but with nice green phantom from the same place, 2 cm large
