Blue quartz, also called Dumortierite, is a stone of peace, expression and order that can enhance organizational 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.
It can help with releasing fear and bringing courage to one's life. It is also a boost for creativity and expression.
