Fluorescent minerals can be fascinating to those who discover these hidden treasures and they often raise various questions. Here are some common questions related to fluorescent minerals.
Located in southwest Kentucky, the Columbia Mine was opened by Andrew Jackson in the early 1800's. It is situated in the famous Illinois-Kentucky fluorospar belt and is but one of hundreds of little mines that have operated in this area from 1800 to the late 20th century. Nearby are several other mines (Eureka and others) but the Columbia so far has been the only one to produce significant fluorescent specimens.
The list of fluorescents includes leucophanite and closely related meliphanite, feldspar, sodalite, rosenbuschite, helvite, apatite and zircon.

This same situation has led to the amazing and continuing underestimation of Ilimaussaq as a fluorescent collecting paradise.

Collecting Fluorescent Minerals is an exciting and very satisfying hobby that combines the appreciation of minerals and their unique optical properties. Fluorescent minerals can be found almost anywhere and are often there just for the taking. A spot picked over by daylight mineral rockhounds can be filled with glow rocks at night - the last person never knowing what was left behind.
"Howie and His White Whale" is a combined report of one man's initial trip and how it turned into a subsequent quest for "Ahab's white whale" of fluorescent minerals - and became an obsession. (Howie has visited the complex with us every year except for the first.)
What are the most common fluorescent minerals to be found with a 365nm UV flashlight? We’ve come up with a list of fluorescent minerals as a starting point. Fluorescent ruby, honey calcite, green opal, aragonite, fluorite, etc.
