I am the vice-president of the 4M association (Micro Mounters of Minerals of Montigny-le-Tilleul).
I am collecting minerals since 1995. This collection is based on micro-minerals and thumbnails.
I have a considerable collection of calcite from Landelies (B). I live near Charleroi in Belgium.
I search contacts with other collectors to make mineral's exchanges ( micro & macro).
