Shattuckite

Shattuckite is a copper silicate hydroxide mineral, Cu5(SiO3)4(OH)2. Wikipedia says it was first found in 1915 at the Shattuck Mine in Bisbee, Arizona, which gave it its name, that it is relatively rare, and that it usually occurs in a granular massive form or as fibrous needle-like crystals. Hall lists its colour as dark and light blue and turquoise, mottled, often small and tumbled, and from the United States. Hall associates it with a raised vibration, the third eye and throat chakras working in harmony, clear psychic vision and the ability to talk about what is seen, and strong protection during channelling. She also links it to automatic writing and telepathy, and to clearing past-life curses and commands to secrecy. She says to place it as suits the purpose. Her statements about health complaints and a spring tonic elixir are her own claims and are not vouched for here.
