this is my interpretation of Rainbow a crystal skull which I was privileged to hold during a visit of DaEl Walker is the Director of the Crystal Awareness Institute. He was visiting the area where I live which is close to the Ancient monument Stonehenge, DaEl was also whilst here to find a crop circle and walk within and place Rainbow in the centre. I found the skull fascinating to hold, it was so smooth with many highlights and colours.this is the link to the website which explains more about this amazing find. http://www.crystalawareness.com/crystal-skulls/index.html
