Idaho’s nickname is the “Gem State” because nearly every known type of gemstone has been found there. In addition, Idaho is one of only two places in the world where star garnets can be found in any significant quantities, the other being India. Idaho is sometimes called the “Potato State” owing to its popular and widely distributed crop.
