The term is used for - at least - three different types of quartz: quartz crystals that appear blue due to the so called Tyndall scattering effect caused by tiny inclusions. Blue quartz brings this sense of order to all things, and releases fear, bringing courage to one's life. It is also a boost for creativity and expression. Emotionally, blue quartz greatly reduces problems with scattered mind and disorganization, and brings mental clarity.
