Fluorescent Minerals are special kind of rocks that fluoresce
(glow) with beautiful colors
under shortwave or longwave ultraviolet light. What causes these
rocks to fluoresce is
based on the chemical composition and trace metallic elements in the
minerals. It is the
trace metallic elements called activators, that is causing
these minerals to fluoresce
under ultraviolet source. Some fluorescent minerals may have two
activators in order to
make them fluoresce.
About 10 to 15% of the minerals in the World are
A short list of fluorescent minerals just to mention a
Calcite - fluoresces a range of colors, either
longwave or shortwave ultraviolet.
Willemite - fluoresces bright green under shortwave
Esperite - fluoresces bright lemon yellow under
Fluorite - fluoresces bright, deep blue under
Diamonds - fluoresces either blue, light green, or yellow
under longwave ultraviolet
In August 1999, I went to Franklin-Odgensburg, New jersey. I
was there to visit the Franklin Minerals museum, Buckwheat Mine Dump
and Sterling Hill Mining Museum. Both museums were very interesting,
especially the Sterling Hill Mining museum.
You can tour through a real zinc mine at the Sterling Hill
Mining Museum. The day I was there, it was about 85 degrees outside,
54 degress and damp in the mine. There were ultraviolet lights in two
locations inside the mine. The Rainbow tunnel and Lanesbury

A Note from
I do want to say something about the
late Charlie Ward. I started collecting fluorescent minerals in 1997.
In order for me to have an excellent fluorescent mineral collection.
I have to search for a dealer who sells quality fluorescent minerals.
I searched on the internet and I came across Charlie Ward's site. I
made a phone call and Charlie answered. I introduced myself, then I
told him that I want to start a collection. He made recommendations
on what to start with and I went along with him. I placed the order.
When the order came, the first batch of specimens were unbeleivable
and the quality were excellent.
I have been ordering fluorescent
minerals every few weeks to build up my collection. To date, he never
failed to satisfy my requirements. We have became friends ever since.
We also made frequent contacts from time to
In November 1998, I stayed at his
home in Norwalk, CT, for the weekend. I was there to help him with
his fluorescent mineral display for the Fluorescent Mineral Society
meeting. We had a good time. I met Richard Bostwick, Dr. Kerry
Cooper, Jared Woodward and many other FMS members, but missed out
meeting Earl Verbeek.
After the meeting, Charlie and I
were in the dark. The only lighting we had were ultraviolet lamps and
the glow from fluorescent minerals. I was picking out fluorescent
minerals specimens for my collection. I went home happy with a lot of
new acquisitions from Charlie.
Sadly, Charlie passed away on April
2, 2013. I will miss the good times we had at the mineral shows and
Charlie, I will never forget you.
