Reference collection chemical elements, profi edition, 9pcs

This set comprises chemical elements which occur in their native state in nature (that means not as an oxide etc.). This reference collection is great for demonstrations and exercises in geology lessons, and for passionate collectors it might be the nucleus of a new systematic collection. The samples come in a stable, high quality wooden box with outer dimensions of 14.2 x 14.2 x 4.1 cm. It is comparted by nine folded boxes of 41x41 mm. We do our best to select minerals which optimally fill the space of the compartments. A label with name (English, German, Czech) and location is attached on the inside of the wooden lid.
Compared to our "value edition" of this teaching collection, the professional edition contains minerals from more rare locations and less micromounts (MM):
