Fluorescent Calcite from the Badger State

This is a single, colorless calcite crystal from one of the lead mines that used to operate in Shullsburg, Wisconsin. Under UV, this specimen shows a subtle, but beautiful, multi-wave response under all wavelengths. It also shows brief phosphorescence, strongest following short wave. The size of this specimen is 50.6 x 47.0 x 27.4 mm, and it weighs 71 grams.

Wisconsin’s nickname, “The Badger State,” has its origin in the lead mining that occurred in the Shullsburg area during the 1820’s. The lead miners came to be known as “Badgers” due to the numerous shallow pits and holes they dug in search of ore.
