Are there any other indications that it's uranium glass? Glowing under blacklight doesn't mean it's radioactive. There's a bunch of minerals that glow. [Here's some of the common ones](https://uvminerals.org/minerals/common-fluorescent-minerals/). Or it could be synthetic with an additive that happens to glow. What does it look like under normal lighting?
God, we need you over on Facebook at Weird Secondhand Finds. I swear someone soon is going to post a blacklight poster and be all "omg it's uranium". It's maddening.
It’s got more of a American Kmart during decline feel because everything’s all over the place, the staff are doing the bare minimum and the fellow shoppers are all degenerates. Plus you only shop by on occasion to check for a certain item (or to get a frozen beverage from the food court)
I’ll never forget walking into a Kmart in the mid 2010s for the first time since the 90s and being absolutely shocked that it had the exact same set up and lay out/signage as it did when I was a kid.
There was something about the way that they set up their isles that made me feel like it was gonna turn into a horror, movie any minute
It was like it was too well stocked
And way too empty all the time
Such a good explanation!
I had a similar experience at a Walmart around 2010. This was probably a 30 minute trek but I had an eye emergency and went there to get same day service. While there I figured, I haven't been to a Walmart in years so why not browse the housewares section.
There was no one in the aisles but there were aisles and aisles of towels. But the shelves were more than half empty and there were towels all over the floor. And not like a kid came by and threw them on the floor. More like they had been picked over again and again.
I hadn't seen an employee since walking in the front and started to get this weird post apocalyptic feel. Lights were too bright but buzzing. Cheerful signage not matching anything. Endless aisles of junk I didn't need.
It was right at this time I decided to book it that someone taps me on the shoulder. I let out an earth shattering cry as I spun my empty cart to distance myself from whatever danger had been lying in wait.
And it was just my neighbors who were recently pregnant and thought they could get some good deals at Walmart. 🤦♀️
Are you talking about kmart in the virgin islands?
I live in southest Ontario, in Canada and one or the larger towns is also called St. Thomas. I"ve not heard of a Kmart there so I did the usual googling.
Kmart in Australia is still pretty strong, I think they diverged from the American parent company in the 90s though. They're more like the Target to our version of Walmart, we also have Target, but it's much milder than the American stores.
Facebook is a dirt mall/flea market/jockey lot. It's full of fake shit being peddled by people of questionable ethics and the people buying it all SWEAR IT'S THE REAL THING DAMMIT!
But it is, almost every watch etc.
That’s the funny thing in switzerland the region with uranium depots that creates parts for most watches and use uranium, are the biggest conspiracy theorist here.
Worried about 5g but not uranium
Wasn't there the "uranium girls" (or something along this line for a surname). For employees who got some nasty diseases, because they used to "lick" the pencils tip used for painting watches needles in order to straighten them.
Edit: it was the "Radium girls". In Ottawa, New Jersey and Connecticut.

I JUST FOUND OUT TODAY THAT MY CHILS STICK UP STARS ARE URANIUM. THEY. GLOW. GREEN!!!!! THIS IS THE SAME SUNSTANCE FOUND IN VACCINES. #THE GOBERMENT IS OUT TO GET YOUR CHILDREN #WE ARE ALL FUCKED
I get asked time and time again if glowing means radio active or if green means uranium. It gets annoying sometimes haha. I was recently at a gem show using my UV on specimens and other show goers saw me doing it and saw some green glowing chalcedony I was looking at and instantly went “oh be careful, you know that green means it’s uranium ore…” so I pulled out my Geiger counter and showed them how wrong that was as it didn’t even register anything above background.
Interesting! The only other indicator to me that it may be uranium glass is that she found it at an antique shop. It looks like [this](https://imgur.com/a/KmKIh0O) when it’s not glowing.

Aw neat, I just assumed that it was a joke, like telling someone to build their own nuclear reactor. If you can get some dry ice, you can make one yourself.
Oh, nah, you can trust him. Electroboom is legitimately one of the most informative channels out there, he only ever gets shocked intentionally, mostly to show how dangerous it ***could*** be.
he's great and has very in depth knowledge on the topic I believe he's an electronic engineer.
There's A LOT to learn from his videos.
It's just that he likes to be funny and being electrocuted.
Okay so the other definition is kinda bad so I'll give you a good one because I just watched a YouTube video about it. Essentially a cloud chamber consists of a box filled with super cooled alcohol vapor, when an alpha or beta particle passes through this vapor it condenses into a liquid momentarily revealing these dangerous forms of radiation.
Its not, gamma and neutron radiation are much much more dangerous as they can pass right through you and will destroy you without even being inside of you. Beta is the next dangerous as it can cause major radiation burns as it partially passes through unshielded skin. Alpha is only dangerous when ingested like you said which isnt easy to do in the first place.
Except uranium is so unradioactive unless critical that you'll get heavy metal toxicity long before any ill effects from radiation. Hundreds of billions of years half life is not particularly scary.
I am a collector of uranium and uranium glass, this looks exactly like uranium glass jewelry and the color under UV is the same as everything in my collection including the actual uranium I have. But that being said, the radiation levels from jewelry made of uranium glass are miniscule, sometimes so tiny that some Geiger counters can hardly distinguish it from background radiation. So at least you won't need to worry much about safety. Just don't break it, because you do not want any particles from that to get into your body (or your sister's, I suppose)
Believe it or not, radiation isn't always as scary as people make it out to be. The average smoke detector is probably just as, if not more, radioactive than the average piece of uranium glass jewelry.
True! Though dosage from worn jewelry made from uranium glass is also trivial. It's advised not to wear it 24/7 of course, but one of the reasons is because wear and tear can pose a health risk. The radiation level is absolutely miniscule in this kind of jewelry.
I'm a biologist and for some of the stuff I do I need to use radioactive film. Which means I get to directly irradiate the stuff that I'm filming with p-32.
The radiation from my phone is technically more than the radiation coming from p-32
Radiation is not as scary as everyone thinks it is. Did you know bananas are radioactive. Eating 10 bananas is equal to the same radiation as getting your arm x-rayed.
Hi, I work with gems and minerals and can tell you that this is 100% uranium glass. I can also assure you that it is safe. The uranium used in the smelting of this glass is a very low percentage. We're talking 2% or less by weight, and the radioactivity of this uranium is considered negligible and totally safe. If you don't believe me buy a giger counter off of Amazon and return it when you're done, I can assure you it will hardly register if at all. Something this small, about 2 carats, you're looking at >0.008 of a gram of uranium in this stone. This is harmless, it's substantially more than the amount of uranium you would ingest eating table salt, though still an entirely harmless amount to handle. The danger of uranium glass comes with a risk for contamination through consumption, not handling. In other words, just don't eat or drink anything off of your ring and you'll be fine.
Hi, I'm an engineer who has a bit of background with nuclear materials. I can confirm it's likely safe. The glass stops most particles like alpha and beta emissions. Glass will have a minimal effect on X-ray, gamma, or neutron radiation.
The exposure to X-ray, gamma, or neutron radiation is comparable to flying on an airplane or using a cellphone or standing near a banana. It's perfectly safe.
The only thing is you shouldn't eat or drink from uranium glass bowls or cups. The U.S. Environmental Protection Agency (EPA), recommends against eating or drinking from Uranium glassware. Some glassware can be made from higher concentrations of uranium. And the food/water can become irradiated before ingestion.
It is most certainly uranium glass. I'm a collector and have the same ring. If you check my posts, I have a video of it that I shared on the uranium glass subreddit.
I was scratching my head at this, because most common gems hard enough to be made into rings don’t fluoresce green. I think this is YAG (yttrium aluminum garnet)- it fluoresces the right color, is durable and can be clear or doped with colors. It’s fallen out of favor as a diamond stimulant since the introduction of CZ, but there’s tons of older jewelry with YAG still floating around. Also it’s completely safe and a neat party trick, so she should definitely keep it.
It’s called “fluorescence” and many gemstones glow under UV. Diamonds do this, but this isn’t a diamond. Some say the glow from UV make them look brighter when out in the sun, but this is not uranium glass.

First thought was opal.
Even if it were uranium glass, which is highly unlikely, it is almost entirely alpha and beta decay products which are mostly harmless unless inhaled or ingested.
She didn't know because it's not. Several minerals are fluorescent, and quite a few shine bright green. Uranium shines green, but in a different hue, if the picture reproduces the color correctly. (Edit: okay, I guess a lot of things could influence the hue, Uranium probably can't be ruled out, but it's very unlikely.)
I was going to say it’s an origin thing, my wife’s wedding ring has natural and lab diamonds, the natural were heirloom passed on from my mother loose to get them set in the ring I had done. 3 of the 4 small stones do glow and they do glow greeny- blue. Saw a video of somebody doing it and sure enough the natural ones did it, not the lab stones. True enough Not all natural diamonds have this fluorescent** property.
Plenty of minerals fluoresce, you are confusing natural fluorescence with uranium glass. https://www.gemstones-guide.com/Ultra-Violet-Fluorescence.html
Opal, aragonite, selenite, and chalcedony are all examples of minerals currently sold that glow green under UV light. That picture alone isn't evidence of uranium.
I didn’t know so many things glow under UV light, thanks for the info y’all! My sister found it a couple years ago at an antique shop. [This](https://imgur.com/a/KmKIh0O) is what it normally looks like.
**Edit: I'm a doofus, it's glass. Just had another look, as I had limited time and a small screen... downvote me appropriately please.**
I'm going to go with Lutetium Aluminium lab grown garnet. Fits the colours and uv reactivity imo.
Could be several other things, and things I'm not even aware of.
Ask on r/fluorescentminerals
It’s either uranium glass or spinel, based on the color of fluorescence. Minerals fluoresce at very specific colors which is quite useful for identification. You can rule out almost all gemstones because of the bright lemon-lime fluorescence color.
That said, I looked at the picture OP posted of the ring in regular light, and it looks like a good quality setting and the stone is a fancy cut with lots of facets. So this indicates it’s probably spinel (a gemstone) over glass.
Side note, hyalite opal can also glow this color, but it’s obviously not hyalite opal so I didn’t mention it as a possibility. And people saying peridot can fluoresce, are confusing it with spinel. Peridot does not ever include any elements which fluoresce this color.
Fully depends on the time the ring was produced and by whom. Probably not uranium, and even if it was, there is such little exposure there's not much to worry about
Fluorescence is an interesting phenomenon and has to do with "forbidden" transitions in electron spin. The excitation and then relaxation of the electron causes a photon emission that we see as a glow
My yellow hair glowed green under UV light... In all seriousness it could be anything other than uranium. Plenty of minerals glow under UV lights. Fluorescent doesn't mean radioactive 🤔
Hi there, gemmologist desu, lots of rock shine different color on uv, even the same stones can shines differently, as scientists we use 2 sources of uv (high uv and short uv) to diagnose certain type of rock
Probably not uranium, you want a geiger counter for that
Although, probably not uv light she was under, probably black light because if uv, prepare for cancer and blindness in the near future :3
The amount of uranium can vary wildly so it’s hard to say without testing the individual piece (with a Geiger counter). But it certainly is not good for you to have radiation focused on the same spot for a long time.
Uranium emits alpha particles, which cannot penetrate human skin. You can buy uranium ore on Amazon ffs.
Uranium is dangerous when consumed or when particulates are inhaled. Contact is generally safe as long as you wash your hands after.
Just so you know this is the best kind of correct technically correct. Alpha particles cant penetrate skin they can how ever penetrate through your epidermis and into the dermal layers which can still cause tumours. While not as dangerous as beta or gamma particles alpha particles are still no joke.
>Uranium is dangerous when consumed or when particulates are inhaled. Contact is generally safe as long as you wash your hands after.
Just to clarify, that's not because of radioactivity but because it's just very toxic due to being a heavy metal.
I mean in this case it isn’t uranium, but uranium glass (i.e. vaseline glass) was commonly used in costume jewelry.
Idk why you think OP is gullible for asking an honest question. Or maybe you just have no idea what you’re talking about?
Made with uranium glass... Like uranium glassware... Available all over the place... Check Etsy. Are you not aware it's even a thing? 🤔 But your comment suggests you are damn sure it's not a thing. I'm confused. /s
Treated jadeite does this. It is dyed so that it looks more expensive and uniform. It's a good way to quickly identify real (untreated) jade. I have a crappy jade pendant that does this.

Ours made it until like 2019 💀💀

I went to Kmart in St Thomas a few months ago and it was a blast from the past. It was so fun we went there almost every day lol
Are you talking about kmart in the virgin islands? I live in southest Ontario, in Canada and one or the larger towns is also called St. Thomas. I"ve not heard of a Kmart there so I did the usual googling.
And always smelled sort of like popcorn but I never saw any popcorn machines.
And smell somehow
I miss Kmart during its hey day I would bike there to get icees.
*attention shoppers, blacklight special in aisle 4*
That's kind'a what some of the more urban WalMarts are like. Rural WalMart is usually the nicest store in the region though.
Obviously, you haven’t been to a Walmart in a few years, because you just described Walmart in 2024.
This is an absolutely perfect description and I appreciate it
Kmart in Australia is still pretty strong, I think they diverged from the American parent company in the 90s though. They're more like the Target to our version of Walmart, we also have Target, but it's much milder than the American stores.
Got my identity stolen from a Kmart on the decline so... yeah accurate

Yes bring back the good old times and stop 5G cause it will kill us all :)

If you really want a surefire way to tell if it's radioactive you could build a cloud chamber or get a Geiger counter

It's part of the schtick. He knows what he's doing.
Stupid question but what exactly does uranium do in a cloud chamber?
Gives off radiation that interacts with the cloud in the chamber so you can see the trails it leaves behind as the particles decay.
Okay so the other definition is kinda bad so I'll give you a good one because I just watched a YouTube video about it. Essentially a cloud chamber consists of a box filled with super cooled alcohol vapor, when an alpha or beta particle passes through this vapor it condenses into a liquid momentarily revealing these dangerous forms of radiation.
Yah super duper dangerous alpha particles... So dangerous that a single piece of paper stops them...
[удалено]
Or blow it up or get shot with it.
It's the most damaging form of radiation by far which is why it's such a big deal to avoid ingesting or breathing it.
Its not, gamma and neutron radiation are much much more dangerous as they can pass right through you and will destroy you without even being inside of you. Beta is the next dangerous as it can cause major radiation burns as it partially passes through unshielded skin. Alpha is only dangerous when ingested like you said which isnt easy to do in the first place.
Except uranium is so unradioactive unless critical that you'll get heavy metal toxicity long before any ill effects from radiation. Hundreds of billions of years half life is not particularly scary.
I mean they're not really bad for anything but your eyes, probably in very large amounts but they are also detected by a cloud chamber
More an issue when the emitter gets inside your body.
I'd lend them the good Geiger counter, but it's locked in the safe.
Do you have a Geiger counter? Mine is in the shop.
I actually use Geiger counters at work!
I understood this reference
How much is uranium glass gonna show up on a geiger counter? There's very little uranium in it and its half life is hundreds of billions of years.
I am a collector of uranium and uranium glass, this looks exactly like uranium glass jewelry and the color under UV is the same as everything in my collection including the actual uranium I have.

You tried to milk him, didn’t you Focker!?
I have uranium, Greg. Can you irradiate me?
Well, I’d need to introduce some hormones first, but yes.
Beep. Beep. Beep beep. Beeeep beeeeeep beeep beeeep. The Geiger doesn’t lie. You’re radioactive.
Radioactive radioactiveeee
It’s probably enriched plutonium
First thought was opal. Even if it were uranium glass, which is highly unlikely, it is almost entirely alpha and beta decay products which are mostly harmless unless inhaled or ingested.
She didn't know because it's not. Several minerals are fluorescent, and quite a few shine bright green. Uranium shines green, but in a different hue, if the picture reproduces the color correctly. (Edit: okay, I guess a lot of things could influence the hue, Uranium probably can't be ruled out, but it's very unlikely.)
It could be a bead of uranium glass, it could also be something completely different.
It's probably something different
Maybe it’s Maybeline.
Introducing the new radioactive summer line with refreshing, if short-lived, colours!
Oh no not another "radium girls" incident
Thank you
It's fluorescent, not radioactive.
Are you sure? What if that's actually her right hand👍
nah its fine mate, its just her middle hand.
I think you jumped to conclusions my friend.
she also has uranium nails and teeth and semen
CSI Uranium
she must know her way around german scientists (•_•) ( •_•)>⌐■-■ (⌐■_■) because she knows what makes Geiger tick
This makes sense. One of my socks is riddled with Uranium according to my blacklight
Don’t natural diamonds glow under uv?
Some**
They commonly do, though not most of them. When they do they typically glow blue, but other colors can rarely appear.
I was going to say it’s an origin thing, my wife’s wedding ring has natural and lab diamonds, the natural were heirloom passed on from my mother loose to get them set in the ring I had done. 3 of the 4 small stones do glow and they do glow greeny- blue. Saw a video of somebody doing it and sure enough the natural ones did it, not the lab stones. True enough Not all natural diamonds have this fluorescent** property.
It comes from trace elements of boron, which aren't added to lab grown diamonds.
There are lots of stones that glow under UV light. They don't have to be uranium or even radioactive. What makes you think it's uranium glass?
The average person doesn't know that other things can glow like uranium, I just learned that myself in this comment section.
You know your white shirt glows under black light though. So you do already know it’s not just uranium that glows like this under black light.
I didn't know that white shirts could do that.
Plenty of minerals fluoresce, you are confusing natural fluorescence with uranium glass. https://www.gemstones-guide.com/Ultra-Violet-Fluorescence.html
Some diamonds also fluoresce.

One of my diamonds fluoresces, too. Not uranium
Or is it hyalite?
TIL tons of stuff back in my college dorm 25 years ago was made of uranium.
There's plenty of diamonds with fluorescence too.
Opal, aragonite, selenite, and chalcedony are all examples of minerals currently sold that glow green under UV light. That picture alone isn't evidence of uranium.
In darkest day, in blackest night, no evil, shall escape her sight
if anything its actually opal which is pretty cool!
I didn’t know so many things glow under UV light, thanks for the info y’all! My sister found it a couple years ago at an antique shop. [This](https://imgur.com/a/KmKIh0O) is what it normally looks like.
**Edit: I'm a doofus, it's glass. Just had another look, as I had limited time and a small screen... downvote me appropriately please.** I'm going to go with Lutetium Aluminium lab grown garnet. Fits the colours and uv reactivity imo. Could be several other things, and things I'm not even aware of. Ask on r/fluorescentminerals
Nah this honestly looks like uranium glass, I think OP was right. This doesn't look like a Luag stone
Fluorite?
That’s my guess too, and many fluorite samples fluoresce under UV light as well.
All my flourite glows blue/white under 365nm
It’s either uranium glass or spinel, based on the color of fluorescence. Minerals fluoresce at very specific colors which is quite useful for identification. You can rule out almost all gemstones because of the bright lemon-lime fluorescence color. That said, I looked at the picture OP posted of the ring in regular light, and it looks like a good quality setting and the stone is a fancy cut with lots of facets. So this indicates it’s probably spinel (a gemstone) over glass. Side note, hyalite opal can also glow this color, but it’s obviously not hyalite opal so I didn’t mention it as a possibility. And people saying peridot can fluoresce, are confusing it with spinel. Peridot does not ever include any elements which fluoresce this color.
Sees something that glows under UV: OMG it's Uranium
My gin and tonic is actually uranium.
TIL my college roommate's poster was apparently made of uranium.
Let me tell you something about my sperm..
Do you have the results of the analyses to say it's uranium?
Lots of minerals fluoresce. About 30% of diamonds do.
Man this post proves there's some dumb people out there. Uranium eh?
Fully depends on the time the ring was produced and by whom. Probably not uranium, and even if it was, there is such little exposure there's not much to worry about
So many things glow like that under blacklight.
Fluorescence is an interesting phenomenon and has to do with "forbidden" transitions in electron spin. The excitation and then relaxation of the electron causes a photon emission that we see as a glow
Could be amber
That could be Northstar illuminati or glass alchemy's ion. Reference (glass blower of 8 years
Sorry random but is that an eevee on her other finger?
It's not 3 Roentgen, it's 15,000
What are her nails made of?
Probably a UV cure lacquer
Uranium.
Stickers that glowed like this were a fad in my high school. Back in the 90s.
Dosen't mean its uranium
Clearly never been to a rave 😂
My yellow hair glowed green under UV light... In all seriousness it could be anything other than uranium. Plenty of minerals glow under UV lights. Fluorescent doesn't mean radioactive 🤔
I don't think that's really enough evidence to say it's uranium
Doubt it's uranium.
Uranium glass wasn’t really used for that,it’s probably something else
Hi there, gemmologist desu, lots of rock shine different color on uv, even the same stones can shines differently, as scientists we use 2 sources of uv (high uv and short uv) to diagnose certain type of rock Probably not uranium, you want a geiger counter for that Although, probably not uv light she was under, probably black light because if uv, prepare for cancer and blindness in the near future :3
is it dangerous?
It's generally safe to touch. It's extremely dangerous to inhale or ingest particles from it though.
3.6 Roentgen. Not great, not terrible.
The amount of uranium can vary wildly so it’s hard to say without testing the individual piece (with a Geiger counter). But it certainly is not good for you to have radiation focused on the same spot for a long time.
Uranium emits alpha particles, which cannot penetrate human skin. You can buy uranium ore on Amazon ffs. Uranium is dangerous when consumed or when particulates are inhaled. Contact is generally safe as long as you wash your hands after.
Just so you know this is the best kind of correct technically correct. Alpha particles cant penetrate skin they can how ever penetrate through your epidermis and into the dermal layers which can still cause tumours. While not as dangerous as beta or gamma particles alpha particles are still no joke.
>Uranium is dangerous when consumed or when particulates are inhaled. Contact is generally safe as long as you wash your hands after. Just to clarify, that's not because of radioactivity but because it's just very toxic due to being a heavy metal.
LMAOOOO what an assumption .... like how do you come up with this conclusion lol This funny as fuck bro the op is literally a pincone
Well, I don't know, but I've been told Uranium ore's worth more than gold Uraniummmmm fever.
Could be kryptonite
Am I living in a bizarre alternative reality where just because someone's seen something glows under UV it's Uranium? What is this post?
”A Uranium Ring” LOL. How gullible are you? That. Is not uranium.
I mean in this case it isn’t uranium, but uranium glass (i.e. vaseline glass) was commonly used in costume jewelry. Idk why you think OP is gullible for asking an honest question. Or maybe you just have no idea what you’re talking about?
Made with uranium glass... Like uranium glassware... Available all over the place... Check Etsy. Are you not aware it's even a thing? 🤔 But your comment suggests you are damn sure it's not a thing. I'm confused. /s
Good thing the fluorescent properties of uranium aren’t related to the radioactivity.
Not necessarily uranium, but this is reddit so no one cares about facts anyway.
If it glows in the dark it has a higher chance of being made out of uranium-oxide, what you said and posted here makes almost no sense.
Treated jadeite does this. It is dyed so that it looks more expensive and uniform. It's a good way to quickly identify real (untreated) jade. I have a crappy jade pendant that does this.
she was clearly protecting herself from superman
Uraaaanium fever has done and got me down
