COBALT AURA quartz: is quartz that has been treated with cobalt, resulting in the crystals having a deep indigo, cobalt blue, magenta and gold colouring. Sometimes this crystal is mistakenly confused with Flame Aura. This crystal shouts "Archaeon Michael" to me, with its deep blues and golds! Strong, protective, reflective and supportive, this is an ideal crystal to carry or wear for protection against unwanted negative influences or psychic attack. It will also support the upper chakras and provide protection and energy whilst channelling, journeying or communicating with Guides.
