This is a very entertaining and informative book. It includes everything and more on what I need to know about the properties of various rocks.

As I am a big fan of communal stoning this book proves to be an invaluable resource. There is nothing more embarrassing than choosing the wrong type of rock at a stoning. I unwittingly chose a rock of very brittle consistency during a recent stoning I attended. You can imagine how foolish I looked when my stone merely disintegrated as it bounced off of my intended targets forehead. I still haven't lived that painful episode down, much to the amusement of my fellow stoners. My nickname is "Ole Softie" now.

Take a lesson from my faux pas; pick up this book before you are made to look the fool.

This book is a must have for any experienced rockhound. The field guide sorts mineral specimens by color and then further subdivides them by crystal habit. The color plates are nicely photographed and direct the reader to the corresponding pages which contain all the mineralogic characteristics of the specimens. All the information a rockhound could possibly desire, including North American collecting locales is contained within.

This would not be a suitable book for a beginner in the field as the retrieval of information would not be easily done by a novice. As a long time serious collector, despite the approximately 800 pages, many popular minerals have been omitted.

This fieldguide is probably one of the best fieldguides out there on rocks and minerals. Being a geology student at Ohio State, I found this book very helpful in the identification of minerals and rocks. It contains an identification key according to hardness and cleavage for minerals, and a key pertaining to rock fabric and hardness for rocks. These keys are integeral to quick identification. One thing I don't like about this book is that the pictures and the text are in two seperate sections. That and the rock section of the book is somewhat lacking. But the main types of rocks are touched upon. However, the book is filled with information, and is very helpful. If you aren't a geologist of sorts, it is somewhat technical, but offers a good glossary of terms, and explains cleavage and other mineral properties well. Overall, an excellent fieldguide for identifying rocks and minerals.
