There have been a couple posts on diamonds the past couple days, so thought I'd give a quick explanation of fluorescence in diamond...

Over the 2018 holidays my daughters were in town.  One left after Christmas but was replaced by my BFF Howie Green and his wife.  Always looking for something to do besides explore the many fluorescent rocks down at my barn, this year we got lucky.  My local glowhound...

I’ve known more than one collector who has been enticed by the brilliant blue/green fluorescence of the mineral gaspeite.  In fact, under the light of a Convoy S2+ long wave flashlight, this material can produce one of the brightest fluorescent responses of any mineral...

A rock just went viral!  A fellow found some glowing rocks on the beaches of Lake Superior and quickly realized how neat they were.  He did some investigating, wandered over to the Facebook Fluorescent Mineral Group, had some ID work done, and confirmed that they were...

The Midwest Chapter of the Fluorescent Mineral Society (FMS) held its first annual meeting at the Ben E. Clement Mineral Museum in Marion, Kentucky, on Saturday, September 16th.  This location was chosen because of its central positi...

There's been some cornfusion about the fluorescence of pyromorphite lately. I'll try and summarize, but invite others to wikify. For our purposes the nicest pyromorphite comes from the Bunker Hill Mine, Kellogg, Idaho, from Cumbria in central England, and from Daoping...

Normally I do not send around a report, but now that I have some responsibility with the FMS, I consider it a duty (and a nice one).  I have been going to the Tucson shows for 30+ years and have seen just about everything, but every year is a...

[NOTE: This is an archive of a Facebook post with a great discussion about the fluorescence of rubies]  "The chromium present in ruby causes a natural red fluorescence which is stimulated by both visible and invisible (ultraviolet) light. However, when a ruby contains...

8/31/17 - A major component of rock collecting (for me) is simply getting out in nature.  A buddy dragged me out to a very remote area here in middle TN to hunt for agate.  Since I'm a pure "Glow Hound" I wasn't anticipating any glow rocks, just the beauty of the area,...

The promise of this year’s Super Diggg on April 29th was too tempting to resist-  over six million pounds of Mill Site rock material, purported to contain copious amounts of rare fluorescent Parker Shaft minerals, would be made available to collec...
