Editorial Reviews

Children's Literature - Carollyne Hutter
One of these statements is true: diamonds are the rarest of all gemstones; sapphires can be blue, yellow, green, purple, pink or colorless. To find out which one is true, the reader explores the topic of gemstones. The book is organized into five chapters: dazzling diamonds and elegant emeralds; out of the earth; animal, vegetable, or mineral; a rainbow of colors; and useful gems. It explores such topics the Mohs scale of hardness, how gems form, gems that comes from organic matter (such as pearls and amber), and cutting diamonds. Glossy colorful photographs capture the beauty of gemstones. There are special sections on birth stones and weighing gemstones. The book closes with a list of true statistics about minerals, a list of books for further information, and a glossary. At the end of the book it tells which opening statement is true. As part of the "A True Book" series this title can be used in science and geology units either alone or with other geology books in the series. Reviewer: Carollyne Hutter
