Did you know that in the 1600's, French and Italian kings believed diamonds and gemstones had supernatural power? The gemstones were worn for protection in battle. The first bride was presented with a diamond in 1477. However, it took almost five hundred years for diamond rings to become the popular engagement symbol. This book, part of the "Rocks, Minerals, and Resources" series, will engage young readers with many facts and great visuals. The topics covered include everything from the processing of gemstones to the lore and legend of the stones. The simple text reads easily and offers fascinating facts on each topic. Young readers will be engaged with the pictures of X-ray machines scanning mining workers for stolen diamonds. A glossary lists unfamiliar words. The book would be a perfect supplemental text for any fourth through seventh grade science curriculum. 2004, Crabtree Publishing Company, Ages 8 to 12.
