For decades fluorite specimens similar to the one pictured below have been collected from numerous limestone and dolostone quarries in the northwest portion of Ohio and adjacent areas in Michigan and Indiana. The quarries are located in a geologic feature known as the Findlay Arch. In the most recent issue (Vol. 93, No.2) of Rocks and Minerals, there is a very good article about this area, describing many of the quarries, their history, and fluorite occurrences.

White Rock Quarry, Clay Center, Ottawa County, Ohio, USA

Lustrous cubic fluorite crystals to 1.0 cm with colorless transparent rims and root beer-colored interiors associated with minor pale blue celestine on a limestone matrix. Collected in the early 1960s.
