1.	Scheelite — Val-d’Or, Quebec   
2.	Zincite in Calcite — Franklin, NJ   
3.	Fluorite — Durham, England   
4.	Scapolite (Wernerite) — Otter Lake, Quebec  
5.	Willemite — Franklin, NJ   
6.	Fluorite & Calcite — Sainte-Ursule, Quebec   
7.	Hackmanite — Mont Saint-Hilaire, Quebec   
8.	Aragonite — Sicily, Italy  
9.	Adamite — Mapimí, Durango, Mexico   
10.	Willemite — Mont Saint-Hilaire, Quebec   
11.	Chabazite — Cross Loop, Chelsea, Quebec

One of my coolest minerals purchased in Tucson this year.

I have a collection of rocks from my mom that was in an old box titled "rocks of Missouri". These photos are of one rock and I have a lot of them. I would definitely appreciate more information. If anyone can help that would be awesome. Thanks in advance!

The first pic is right after I turned off the uv. The second one is under direct 365nm light, and the last 2 are under a regular white LED light

Here are my recent finds at Sainte-Marie-aux-Mines Mineral & Gem Show 2026.

Pic 1 is under UV 365nm, pic 3 is under UV 310nm

From upper left to bottom right we have:

Hyalite opal from Mexico, Calcite on Pyrite from Peru, Adamite from Mexico, Pyrite on Calcite from Peru, a last Calcite on Pyrite from Peru (my favourite, amazing color under UV), Pagoda Calcite from China, Zincite from Poland (synthetic), Amber Selenite from Germany and the last, Blue Prehnite from Tanzania.

I PC Rogerley/Diana Marie Flourite from Durham, England. I love seeing the change in color when I take one of my pieces outside. I need to invest in a proper display case with black lights soon.

vanadium beryl from nigeria showing fluorescent bands under longwave uv

Hello all, I have a puzzle I'm trying to figure out. Wondering if anyone here has any clues.

This beryl was sold to me as a Hogg Mine specimen. However, after buying, I noticed it has a large section of high fluorescence under shortwave. I suspect the fluorescence is caused by a light coating of hyalite opal, though not positive on that.

Anyway, I'm pretty sure after doing some research and asking someone I know who works at the Hogg, that this specimen is probably not from that mine.

My question is, does anyone have any ideas about where this beryl could be from generally? Not looking for exact mines obviously as that would be pretty hard to determine. However, has anyone seen large beryl with high fluorescence before and happen to know where it might be from?

A friend of mine told me they found some chert nodules that were fluorescent at a local creek, so of course I had to check it out. I need to work on getting better pictures but there were a fun surprise.

Microphoto of autunite from Mina Assunçao, Aldeia Nova, Viseu, Portugal

A stunning find deep in the hills of the UK.

I was helping family in whistler over the weekend. Above their condo, there was what appeared to be a well weathered chlorite schist with small cubes of Pyrite with a large well formed Calcite banding next to it. I noticed that the calcite reacted to 265nm weakly, giving a pale orange in places, and blue in others. I managed to grab a piece of the calcite and chlorite-schist and this morning tried both under a 254nm lamp. The Calcite gives off both hot pink and blue, and the Schist gives off a pale yellow and pink fluorescence, likely as a result of Scheelite (CaWO4) and manganocalcite. There is evidence of pyrolusite in the calcite.
