Franklin & Sterling Hill

If you are looking for something in particular, please contact us.

Please note that a special lamp (filtered short-wave UV) is required to see the fluorescent colors of these rocks.  It's worth it to get a good lamp.
An ordinary "blacklight" will not work for most of these minerals.
