Some feng shui practitioners recommend ammonite , an iridescent ammonite shell used as a gemstone, as wealth cures. Ammonite may be known by the trade name “kirin stone”, after the mythical Chinese composite animal, more commonly spelled qilin or ch'i-lin. They symbolize non-violence, virtue, and longevity. The iridescence of ammolite is said to resemble their fiery scales.
19th century English texts say the Chinese call ammonites the "kosmos stone", for its resemblance to their symbol for the cosmos. They mean its comma-like shape resembles the black and white sections of the taijitu (“yin and yang symbol”), especially as a pair. The spiral of an ammonite is believed to draw in chi (“spiritual energy”) and radiate it out, promoting abundance, health, and well being.
