About

There are over 6,000 different mineral species! You might be surprised to learn they crystallize in on of only 7 different crystal groups (called "systems"). Crystallography is a fun part of minerals and mineral collecting. In this book you will discover how crystallographers describe different crystal forms. The descriptions can be a challenge to understand, so the book includes 9 cut-and-fold crystal models so you can see the forms and symmetry that is described in the book. And there are many wonderful drawings of real crystal specimens so you can see and, if you want to, color.
