UPDATE (November 2013): The web sites seems to have changed the location of the embedded video here is a link if above does not work: http://sciencefriday.com/blogs/10/24/2011/mineral-madness.html
Science Friday on NPR posted a very informative yet brief video about the minerals at Franklin, New Jersey. When it comes to shortwave ultraviolet fluorescent minerals, it is hard to top those found in Franklin/Sterling Hill, New Jersey. It is fun taking pictures of these minerals when lit up with ultraviolet light.

Here are some more pictures of a friend's mineral from that area. It is for sale if any one is interested. Note you need a shortwave ultraviolet light to view the fluorescent colors.
