FE 1-4, April 1999
Fellergraben, Lungau, Salzburg, Austria
Large single crystal grown as a floater specimen. Colored slightly light green by chlorite in some areas, and reddish in other areas by hematite. One face of the calcite shows a special feature: increased growth at the edges. This rare kind of crystallization can be recognized very well in the photos.
