Crystals are all around us -- in our plants, our homes, and even in our bodies! Eyewitness: Crystal & Gem describes the seven basic shapes of crystals and other aspects of crystallography, including how they form in nature, how crystals are studied and identified, what gives them their amazing color, and how they are used in everyday life. For over 25 years, DK's Eyewitness books have been the most trusted nonfiction series in classrooms, libraries, and homes around the world. In summer 2014 this award-winning series will get a fresh new look both inside and out. The introduction of paperback editions, eye-catching jackets, and updated interiors ensure that the Eyewitness series will continue to be relevant in the ever-changing world of education and remain the go-to source for homework help, research projects, reluctant readers, ESL students, and, as always, to satisfy the minds of curious kids.
