The specimens used for gem-quality ammolite originate almost exclusively from the \u003cstrong\u003eBearpaw Formation\u003c\/strong\u003e of southern Alberta, Canada — a shallow inland sea deposit where exceptional preservation conditions allowed the original aragonite nacre of the shell to survive fossilization with its iridescent microstructure intact. The result is ammolite: an opal-like gemstone composed of thin-film aragonite layers that produce spectral color through light interference.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAge:\u003c\/strong\u003e Approximately 70–75 million years (Late Cretaceous)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineral composition:\u003c\/strong\u003e Aragonite (CaCO³) with trace silica, pyrite, and calcite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptical phenomenon:\u003c\/strong\u003e Thin-film interference (similar to labradorite and opal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary source:\u003c\/strong\u003e Bearpaw Formation, Alberta \u0026amp; Montana\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness:\u003c\/strong\u003e 3.5–4.5 Mohs (ammolite face); matrix varies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eHistorical \u0026amp; Cultural Significance\u003c\/h2\u003e\u003cp\u003eThe \u003cstrong\u003eBlackfoot Confederacy\u003c\/strong\u003e (Siksika, Kainai, Piikani nations) of the northern Great Plains have revered ammolite for centuries, calling it \u003cem\u003eIniskim\u003c\/em\u003e — the Buffalo Stone — and using it as a sacred talisman believed to attract buffalo herds and bring prosperity. Ammonites appear in the fossil records of nearly every ancient civilization: Roman naturalists called them \u003cem\u003ecornu Ammonis\u003c\/em\u003e (horn of Ammon) after the ram-horned Egyptian deity; medieval Europeans called them “snakestones” and attributed them with healing and protective powers.
