Unlike the dense and highly technical academic tomes that are text-heavy, poorly organized and intimidating, this colorful and easy-to-use reference guide dedicated to collecting rocks, gems and minerals is ideal for readers who want to expand their understanding without getting lost in a labyrinth of science.
