This textbook-size (7.0" x 9.25 ") guidebook by Ronald Louis Bonewitz presents interesting facts about hundreds of different rocks, gems, minerals and fossils. Contains 360 pages with hundreds of full-color illustrations and an index - a very nice book at a bargain price. Highly recommended.
Smithsonian Rock and Gem
This is the book that we recommend to people who do not have formal education in geology but who are interested in learning about rocks, minerals and gems (although "mineral" is not in the title this book contains lots of information about them).
It is a great book for reading, reference or study. It has expert and accurate authorship. It is written in a very interesting style and has lots of excellent photos.
