A section of an Ammonite with mixed colored iridescence (which is more noticeable and attractive in person than the photos). In a couple of small places, the iridescent layer has flaked off and the underlying darker colored layer with suture marks can be seen. The open end of the specimen is filled with yellow colored Calcite crystals which fluoresce under LW.
Condition: Fairly Good
Flaws: The iridescent layer has flaked off in places.
