What is Ammolite?|
December 17, 2013 | Geology.com
Ammolite is a trade name given to a thin iridescent aragonite shell material that is found on two species of extinct ammonite fossils (Placenticeras meeki and Placenticeras intercalare). Gem-quality Ammolite produces a spectacular display of iridescent color when it is observed in reflected light. The colors of an individual stone can run the full range of the visible spectrum or be limited to just one or two colors. The color display can rival fine opal and labradorite in its intensity and beauty.
