"...a pretty compendium of exceptionally fine full-color photos of a large variety of minerals and gemstones, some in their native matrixes or in a natural state, and others shown polished and burnished and faceted, glittering as jewelry, coins, unset gems, or decorative objects....informative captions. Longer texts introduce various groups of minerals and gems and are followed by paragraphs on specific types....Attractive and readable...includes such details as preparing for a field trip, cleaning and displaying a collection, and a helpful glossary."-- School Library Journal .
Conversational, and hard to rate. In some ways it rubbed us the wrong way, with incomplete information and generalizations, but to be fair it's probably a good book for beginners and simple public reference. Wouldn't trust it for details. You can easily read it straight through, unlike with some other reference books. It has a reasonable amount of photos. 3.5 to 4 stars, a good junior library general title, gift shop book, etc.
