This little book was very interesting and provides information about the minerals in Arizona. I enjoy using rocks and gems in my jewelry making. The pictures were nicely done and the information easy to read and understand. I would recommend this book to anyone interested in rock collecting or jewelry making - good overview of natural stones. Although I normally prefer a more detailed reference, this is a very useful quick guide.
