Lévyne

This page is currently not sponsored. Click here to sponsor this page.
Colour:
White
Lustre:
Vitreous
Hardness:
4 - 4½
Name:
Named by David Brewster in 1825 in honor of Serve-Dieu Abailard "Armand" Lévy [November 14, 1794 Paris, France - July 29, 1841 Pecq near Saint-Germain, France], French mineralogist and crystallographer, Paris University, France. Lévy used the nickname "Armand", partly as a personal preference and partly to avoid anti-antisemitism.
Zeolite Group.
NOTE: The zeolite mineral species epitaxially overgrown on levyne in all cases is identified as erionite (Passaglia et al., 1998).
