Ammonite fossils predominately found Alberta (Canada) that display iridescence by compression and mineralization of the Ammonite fossil. These iridescent Ammonites are often of gem quality when polished. In no case would this iridescence have been visible during the animal's life; additional shell layers covered it.
The spiral shape of these fossilized creatures symbolizes continual change and evolution. The Ammonite draws off all negative energies. Think of the Ammonite spirals as a filter, drawing in these dense energies which are no longer needed, moving them through the spirals and releasing them as fresh, positive, loving life force energies.
The Ammonite is a very powerful earth healing fossil. Ammonites have absorbed cosmic energy over eons of time and help to stimulate the life force (Chi) within.
It is often recommended to keep an Ammonite in your home to attract health, prosperity, and success.
