    IRIDESCENT GEM AMMONITE
    Placenticeras meeki
    Cretaceous
    Bearpaw Formation, Southern Alberta, Canada

    An exquisite example of precious gem ammolite, one of the world's rarest gemstones. The shell of this ammonite has been transformed over millions of years from plain old mother-of-pearl to the wonderfully colorful iridescent material we see today. This process is observed only in specimens from a small area of North America, making them among the most sought-after by fossil collectors. Most are subjected to intense compression, many emerging almost completely flat, but the present example retains a good degree of three-dimensionality, and flashes with lovely golden greens and reds, and even a hint of the much less common purple and electric blue. Of attractive size, it measures 11 inches in diameter.
