Introductory Rock Kit
Cornerstone's Introductory Rock Kit includes sixteen numbered and hand-selected samples from all over the U.S. representing each of the major rock groups (igneous, sedimentary, and metamorphic). The generously sized specimens (1-2 inches each) are housed in a compartmented tray inside a sturdy box for years of use.
Plus, the Introductory Rock Kit includes a full-color image key, numbers for labels
- and many more!
Instructions come in each box, but we know sometimes things can disappear. So if you need another set of instructions, let us know and we would be glad to email you a new copy.
