Gem Focus June 2021: Fluorite

Brightly colored crystals of fluorite, a.k.a., fluorspar, in large sizes have been a prized possession of mineral collectors for hundreds of years. This calcium fluoride mineral was first named by Carlo Antonio Galeani Napione in the late 18th century. He was inspired by the Latin word “fluere” meaning “to flow" because the mineral is used as a flux in iron smelting for industrial purposes.
