Blue quartz, also called Dumortierite, is a stone of peace, expression and order that can enhance organisational abilities, self-discipline, and orderliness. This enhancement is believed to be due to the effect it can have of balancing the throat chakra and enhancing communication between lower chakras (physical) and higher chakras (mental/spiritual). 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 disorganisation, and brings mental clarity. It also helps one to see and accept reality, and react to it intelligently on one's behalf. It can lift depression and replace it with peace and happiness. It also can help reduce stubbornness, particularly stubbornness that is ultimately bad for one.
Blue quartz helps reduce emotional tension. In the psychic and spiritual realms, blue quartz brings spiritual development, and contact with spirit guides and angels. It can also help you express your spiritual thoughts and dreams. Blue quartz is excellent for peaceful mindfulness or meditation.
Physically, blue quartz can help with cooling the body, throat, thyroid, and parathyroid, detoxification, over stimulation, hyperactivity, spleen, endocrine system, blood.
Blue quartz is associated with the throat chakra, and it enhances communication between the lower and higher chakras.
