Opalized Ammonite Fossil - I
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)
