Orange Calcite.

This is one of the exhibits in the Sedgwick Museum of Earth Sciences, Cambridge. Calcite is common throughout the world and this is a lovely specimen of the orange variety. Healers often use it for problems with kidneys, pancreas and spleen. Also to treat depression. I'm not sure how they use it though. It's Magical use is to remove obsessive behaviour, invocation and manifestation. It is an interesting place to visit.
