The crown chakra is located at the top of the head, aptly named, as it is at the position where you would place a crown on your head.
The colours that the crown chakra corresponds with are white and violet.
This chakra helps you connect with Spirit and receive Divine guidance and inspiration. It helps us open our consciousness and access the higher power of the universal mind.
Great crystals to use to help open and heal the crown chakra are clear quartz, diamond and amethyst.
