Fluorite with Calcite

A classic example of fluorite with calcite dating from the late 1800’s working of the Wheal Mary Ann .  The mineral specimens that came from these mines are now very rare , although if you read some of the old records from the mines there it is recorded that the crystal bearing cavities were often so large that they were utilized as ore passes and access from one level in the mine to the next!.  Incredible to think of this.  This specimen is typical of the association of calcite on pale green fluorite cubes from the location.
