Opalized Ammonite Fossil - B

An opalized ammonite fossil. Look for the iridescent rainbow sheen on the shell. Each one is around 1 inch across.

Stone Facts:

  • "Opalized" is a trade description: the rainbow sheen comes from the shell's original layered aragonite (nacre), which splits light like mother-of-pearl
  • Ammonites are extinct marine molluscs, related to modern squid and nautilus, that lived from about 400 to 66 million years ago
  • The shell was replaced by minerals during fossilisation, preserving the spiral chambers
  • Ammonites are widely used by geologists as index fossils to date rock layers

Traditional & Folklore Properties:

  • The ammonite spiral appears across ancient cultures as a symbol of continuity and growth
  • Traditional associations: in crystal tradition, linked with the Root chakra and Capricorn (shared as folklore, not as a claim of any effect)
