Collection de cristaux, 25 pièces

Collection of 25 pieces, housed in a case 170 x 245 mm, with plastic inseeeerts measuring 45 x 30 mm.
The crystalline form specific to each mineral reflects the molecular or atomic structure. With the user of appropriate ancillary equipment it is thus possible to demonstrate the physical and chemical characteristics of the crystals which are dependent on the structure. In additon, knowledge in the field of crystallography is one of the prime requirements for understanding mineralogy.
The collection contains examples of all seven classes of crystals. The Miller indices for the major facets are noted on the labels.
