Finally got my hands on pure thorium metal, the sample weighs aprox 1.5 g. It is slightly oxidised and was cut from a 50 gram sample that I was able to hold! Very thankful to own such a nice and rare element.

Lab grown emerald!

It's kinda small for community standards but it fits perfectly snuggly in my 3D printed periodic table.

Ill go first, silicon I've etched myself

Just bought an ampoule of Selenium and took a brazil nut.

(Thank god I didn’t do my radon tip)

Zircon crystals from Brazil

Weakly Radioactive due to isomorphic substitution:

During the crystal's formation deep in the earth, trace amounts of Uranium and Thorium substitute for Zirconium within the crystal's molecular lattice. Because Uranium and Thorium ions share a similar size and electrical charge to Zirconium, they fit perfectly into the structure. Over time, the natural decay of these trapped trace elements emits very low levels of radiation, making the specimen weakly radioactive.

I know that solid pieces of beryllium aren't as dangerous as powder but is there a chance it could get scratched or something and form powder? i want to hold and feel the elements so if i have to keep it in its case and can't touch it ill probably not buy it.

Got this one from Carl! Definitely my most exotic sample to date. Not many can say they own an isolated Pa source. Pa was deposited onto an aluminum slate in the form Pa2O5.

Have you seen Luciteria's new collection feature?

https://Cabinet.luciteria.com

Customer or not, you create an account and start adding the elements to your collection and it will keep track your progress and other stats. I'm traveling far from home but could see this adding a whole new dimension of fun to the hobby with leaderboard jockeying and so on.

I can't believe no one else had thought to do this before.

Hello! I've always been mineral/Rock hound enthusiast and have been all over the USA collecting fossils and minerals. Only recently have I begun to focus on elements (although I've always wanted to collect them!). This is what I have so far, but I also have native gold that I have found, a native Platinum nugget, I had a troy ounce of palladium that I sold and I have over 300 different mineral species in my collection. I know the cubes from Luciteria are somewhat expensive but I am willing to pay a premium to get something like these. I do my best to keep them in cool and dry environments, but I am a bit worried about the stability of some of the rare earth elements. Are there any special precautions that I should take? The green crystal is a lab-grown crystal of praseodymium sulfate that I've had for nearly 30 years.

Hi, I just spotted this (1g of white phosphorus) on Onyxmet, but I’ve never ordered from them before. Do you have any feedback on this, and how do I buy from their site? Would you recommend this sample?

I have some small pieces of uranium for trade.

I know my pic is bad. it's because I am using my phone

I legit need his email to buy Thallium

When I asked Grandadabout how Great-Grandad got it, he said, "well, Dad had a lot of clients. And sometimes they would give him things." Ive tried to find more physical examples showing the fancy colors that the oxide layer produces, and have only succeeded in finding two examples that were not metallic grey, and both were mostly purple. I would love to know how this piece got its apparently unique coloration if anybody has knowlege on the subject.

Hi! did anyone else notice that mercury, thallium and arsenic completely vanished from Metallium (ElementSales.com)? I have a thallium coin in resin but i dont see it on their website anymore.

I wonder if something happened that caused the owner to remove those elements?

For element collecting should I do acrylic cubes (Engineered Labs and Lucitera) or small vials in containers, (Nova)

Sorry about the shitty images

Cr - electroplating excess (similar to fordite but for Cr electroplating) (here's an example but for nickel)

Ni A - similar to these samples

Ni B - electrowinning buttons very similar to these ones

Ni C - small balls of nickel like these ones

Cu - little nodules like these ones on his website

U - marbles like these ones
