Fluorescent LW

This Fluorite specimen is composed of a single large crystal. Like all of the Fluorite from the Rogerley mine, it fluoresces a brilliant blue under longwave This is large for a single crystal from this location. The specimen is in fairly good condition. Although the predominate corner is damage free, there is a small chip missing from one of the edges near it. The other corner has damage. It has been treated with a silcone spray which is the case with the vast majority of specimens from this mine which were imported into the US.
