<h2>Physical Description</h2>
These crystal models are composed of a lightly colored Pearwood. Each model is precisely shaped with correct angles to illustrate various examples of seven different groups of crystal structures: isometric, tetragonal, hexagonal, orthorhombic, monoclinic, triclinic/trigonal, and twins. Some have been carefully sanded to represent natural curvature of face edges. Because each individual model is unique, the length varies from 3 to 7 centimeters, the width varies from 2 to 7 centimeters, and each has a unique weight. Some have identification numbers carved into them, which pertains to their original kit number given by the manufacturer. Some have hand written numbers in black ink on their flat faces, which identify the name of the crystal they represent.
<h2>Functional Description</h2>
These wooden crystal models were created as educational tools. The intent is to aid in the naming and identification of crystals by type. Each category of models is labeled in a separate box at the A.E. Seaman Mineral Museum. These models are still in use today at Michigan Technological University.
