Glowing rocks! [Best viewed in dark mode]
Fluorescent minerals emit colorful visible light when exposed to invisible ultraviolet light. Shortwave mineral lights, longwave LEDs, and even ordinary black lights can activate this luminescence.

Brief phosphorescence of a calcite chunk
I just noticed that if I hit this guy with some strong white light it’ll phosphoresce a bit.

This is my piece: Colemanite (phosphorescent), Furnace Creek Borate District; Death Valley Area, Inyo Co., Ca - Size: 3.2" x 2.3" x 2" - Hardness 3.5 - 4 .. Luster of the mineral vitreous to adamantine. --- In Long Wave, it phosphoresces a pale green. -- In Short Wave, it phosphoresces a pale blue.

Is taking a UV blacklight torch to a rock beach at night a good start?
I have just barely started the hobby of beach combing and collecting sea glass and cool rocks and thought my trip to Maria Island, Tas, in a few days would be a cool opportunity to try something new. I have a little UV blacklight torch that I use to see scorpions at night and figured I'd take it and check out Fossil Beach at night. Am I likely to find much in the way of fluorescing minerals or glass with this torch? I'm sorry I don't know the specifications of the torch just that it's fairly small and was quite cheap.

Midnight Minerals FULL-WAVE Triple UV LED Flashlight reviews?
Anyone ever buy/use the full wave light from Midnight Minerals?
Pretty expensive, so wanted to see if anyone had tried it out yet. Battery life, output, etc.

How was the Ultraviolation show?
For those who went to the Ultraviolation show, I was wondering how it was. I hope to go to one in the next few years, and think it's awesome they have a show dedicated to fluorescent Minerals!
Did they have some cool displays or talks?
Was there a lot of unique stuff that you normally don't find other places?
How were the prices? Were there deals to be had or were they typical eBay or other online market type prices?

In 2015, FMS Member, Jennifer Moore came up with this very cool way to display your Glow Rocks. There are 24 cars including the Engine

A huge stupid mistake by me.
I went to a mineral show today hoping to find some nice fluorescent rocks. I made sure I got my powerful UVLW light with me and we headed off. At the show, I find some interesting pieces. I take my LW out to see how they fluoresce. I click on and no light! I have been using it a lot and didn't realize I needed to charge the batteries. Worse... I have an extra pair already charged I could have replaced and no worries. So I had no way of finding anything I may have wanted to purchase. I have many specimens and hard to find something new as it is. But a major rookie mistake not to check your light? DUH to me! That was a first... AND LAST!

First post here, Hyalite opal!

Is the flash just the camera, or is it typical for minerals to flash UV back. All my other pieces just fade away this one almost pulsates. Self collected honey calcite, CTX.
It’s honestly too dim to see without the camera so I’m just asking if other minerals are known to do the same. Or if I need to get a new phone for minerals lol

Obsessed with how petroleum included fluorite looks like a beautiful galaxy

Looking for advice- self built display lights
Hi all, I would like to build a lighting system for my display. It has two levels and the shelves are 1 m wide. I would like to have high CRI visible light, 365 nm and 255 nm UV light. I‘m looking for advice on emitters, power source and any additional electronic components needed. If the questions didn’t make it obvious- I‘m a complete noob when it comes to building anything electronic.
