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

Serious question here. I just had cataract surgery and can now only see FS with sunglasses on. Does anyone know if this will improve as I heal or am I doomed to wearing sunglasses to see my beloved rock? I am using a cheap harbor freight light but my husband says he ca...

Friends don't let friends use crappy unfiltered 390nm flashlights.

This is an educational post, directed towards folks new to the hobby. There has been discussion in our FB group lately about using cheapie 39Xnm flashlights for fluorescent minerals. I am passionate abou...

A pet peeve of mine is honesty in advertising.  Over the past 3+ months I’ve seen companies advertising ever higher power Convoy type flashlights – usually with an LG LED. Every single one of these ads is misleading – I could say downright lies but my bet is that the f...

People new to the hobby of fluorescent minerals typically have a lot of questions about UV.  What is the difference between shortwave (SW), midwave (MW), and longwave (LW)?  Is UV light harmful?  What kind of bulbs/tubes/LEDs are needed to generate UV?  I came across a...

There is something I call the "feldspar effect". When people first start collecting fluorescent minerals in the field they usually are amazed at the typical fluorescence of your average feldspar. As they gain experience and see more fluorescent minerals they realize th...

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...

Ultraviolation Fluorescent Mineral Only Show - "If it don't glow, you're at the wrong show"

Over the years most of the folks I meet in our hobby are old and retired (I'm one of the old ones).  We need yunguns to develop an interest so our hobby continues to grow and we have new blood around to carry our backpacks filled with rocks.

I came across a Youtube vide...
