Ammonite is not a gemstone but a fossil. The name Ammonite was inspired by the spiral shape of their fossilized shells, which somewhat resemble tightly coiled rams’ horns. Pliny the Elder (d. 79 AD. near Pompeii) called fossils of these animals ammonis cornua (“horns of Ammon”) because the Egyptian god Ammon (Amun) was typically depicted wearing ram’s horns.
ammonites are considered a powerful feng shui cure! This basically means that ammonites have a very strong energy that can shift the energy of any space, be it home or office, to a much higher / better quality of energy.
