If anything is "glowing", I wouldn't want it anywhere near my lap! (Just sayin'!)  I've looked at several pictures of Nebraska Blue Agates lately...and you know I'm the furthest thing from knowledgeable about identification...but it looks very much like the pictures I've seen lately... It's gorgeous, whatever it is...  |

That's cool. I didn't know Nebraska had blue agate. I had to go look it up. Once again, I learned something new today. |

Interesting what different lights show us. Black light seems like an oxymoron. I wonder if any critters actually see the world through black light eyes....

I know that at least bees can see in the ultraviolet spectrum, don't know what else can. I've seen photos of how they perceive flowers.
"Their ability to see ultraviolet gives them an advantage when seeking nectar. Many patterns on flowers are invisible to humans."

Trying this again on PC www.beeculture.com/bees-see-matters/
While editing that, I ran across more info on other animals/insects that can also see in infrared.

"From insects to fish and even certain species of mammal, this trait is quite common."
Yes, interesting info indeed!

Pet stains on a rug will glow like that too.  |

So will certain other human bodily fluids, including blood.

Like others, it took me a minute to look, but there it is...Nebraska blue agate. Can't say I've seen anything about it here on the forum. A quick search shows there are a couple mentions, but nothing I've ever seen. Great finds, they light up under that UV.

I don't know about Nebraska Blue Agate but a lot of the material I have from Burro Creek, Arizona glows green under UV light.

I understand that deer see UV. Hunters that washed their camo clothes in "optical brightener" detergent wonder why they get spotted? Well, they glow.
I love putting collected rocks under UV. It opens up a whole new type of collecting. If I get back on my feet later this year, I want to search some creeks at night with UVB near where diamonds have been found, to see if one glows back at me. However, in the area other rocks also glow.

A quick search shows there are a couple mentions, but nothing I've ever seen. Great finds, they light up under that UV. I've found some before, I think I even made a cab out of it once. I'm going to order one of the lights and see what it does. Apparently fossilized teeth glow fluorescent orange,there are some of those around here also... |

I've looked at several pictures of Nebraska Blue Agates lately...and you know I'm the furthest thing from knowledgeable about identification...but it looks very much like the pictures I've seen lately... It's gorgeous, whatever it is... There is a difference between stuff that glows on its own, and stuff that needs UV to excite it. Plus, we all know from quality B movies that the dangerous stuff pulses and makes a woo-woo-woo sound. |
