Description:
This fine example of fluorescent Alabama calcite was found in limestone riprap in the City of Birmingham and was likely quarried somewhere nearby, as there are many limestone quarries in the area. It illustrates the rich and subtle mix of pastel colors that one typically sees in so many of Alabama\'s fluorescent calcites, and it is exceptionally bright. Shown here are the LW and SW UV fluorescences and the view under room light.
