optical properties, Dana's New classification, Strunz classification, mineral
specimen images, and alphabetical
listings of mineral species. There also are extensive links to other
external sources of mineral data and information.

What is a Mineral ?
Selected mineral definitions spanning the last century defining the mineral kingdom as matter other than that of the plant or animal kingdom.
This section contains tutorials on the 36 crystal classes. Along with this information are links to tables
of each class with all the minerals in that class. Printer-ready PDF files of
paper crystal models (assembly required) of the crystal classes can be found here.
3D Crystal models of minerals use JAVA applets
that can be viewed in a browser window. The rotating form on your left is
an actual java applet and not an animated GIF image. If the model is not
visible then install JAVA on your PC.
