Prehistoric Venus figurines such as the Venus of Berekhat Ram may be as old as 800,000 years, and are carved in stones such as tuff and limestoneIntuitive sources believe that Shaman Stones are deeply connected with the Earth. The stones are both grounding and energizing. Shaman Stones may be useful in connecting with one’s animal guides, and in providing psychic protection. They may also help with the purification of negative energies. Use on the third eye is said to enhance psychic abilities. Shaman stones have been used for centuries by spiritual tribal members (Shaman) and other mystics. They are considered sacred among the sages of many ancient tribes.
