1st and 7th chaklras chakra.  These are rare and unsual healing stones composed of Iron Pyrite and Quartz. Super unique stones because Pyrite is grounding and Quartz is astral. During meditation I find that the Keyiapo stone allows me to venture into the higher plane of existence while feeling at ease and protected.  I was able to access the Akashic records (A theosophical term referring to a universal filing system which records every occurring thought, word, and action.) and actually remember what I discovered about myself.  To access the Akashic records via the Keyiapo Stone, place it above your head, the 7th chakra,  during your meditation.  I also feel that these stones offer the most protection of any healing stone against negativity and bad energy.
