Agatized coral, Withlacoochee river bed, Florida

Not so much fluorescent minerals in Florida. This one is darn "purty", though: Agatized coral, Withlacoochee river bed, Florida. Photos in natural light, LW and SW/MW combo. Organic matter and some uranyl cause the fluorescence. (courtesy of the MKA)
