Ammonite
The Ancient Coil of Spiral Wisdom
Also known as: Shaligram
About the stone
Ammonites were marine mollusks related to squid and octopuses, best known for their coiled, chambered shells; they flourished during the Jurassic and Cretaceous periods before becoming extinct about 66 million years ago. Their fossils have been recognized since antiquity, so no single discoverer is credited; their name derives from the “horns of Ammon,” reflecting their resemblance to the ram’s horns associated with the god Ammon. Found on every continent, famous collecting locations include Whitby and Lyme Regis in England, southern Germany, and Morocco. In English folklore, ammonites were “snakestones”—serpents supposedly turned to stone by Saint Hilda of Whitby—and some collectors later carved snake heads onto fossils to reinforce the legend.

Care and handling
Ammonite is a fossil and its condition varies. Calcite-preserved shells are relatively soft and can be damaged by acids, vinegar, harsh cleaners and prolonged soaking. Dust with a soft brush and wipe with a damp cloth, then dry. Some specimens are stabilized, polished or dyed, so avoid soaking and handle them gently.
Individual experiences with Ammonite vary. Use it mindfully as a symbol of deep time and quiet persistence.
