Manuel Quiring

L'intensité des couleurs n'est pas mis en valeur sur ces photos, elle est vraiment flamboyante.
L'ammolite est une pierre ornementale d'origine biogénique, d'aspect rouge-verdâtre et irisé. Elle provient exclusivement de l'est des Montagnes Rocheuses, au Canada et aux États-Unis. Elle est issue de fossiles d'ammonites (70 Millions d'années), des Placenticeras de la formation géologique de Bearpaw Shale. Ces fossiles contiennent de l'aragonite, soit le composant principal de la nacre.

Elle est considérée comme une gemme officielle par la CIBJO depuis 1981, l'année qui a vu commencer son exploitation commerciale. En 2004, elle a été désignée comme la gemme officielle de la Province de l'Alberta, Canada. En bijouterie, l'ammolite rivalise même avec l'opale.
