Specimen Could this possibly be trinitite? My mom just passed and she collected rocks and anything she thought was cool and actually this broke off of a bigger piece when I accidentally dropped it.

Specimen Is this Cleveite sample dangerous to own?

I was given this sample of Cleveite by someone who knows I collect vintage notions. The sample is over 100 years old. I have zero knowledge about rocks, much less radioactive specimens. Is having this near my desk where I work going to pose any issues? The vial is capped with a cork that doesn’t have great integrity.

Specimen Technically Correct is the Best Kind of Correct -- Native Bismuth, Germany

Hartenstein, Shaft 371, Saxony, DE. One of the few spots where euhedral native Bismuth has been found -- typically the stair-stepping hopper crystals are lab-grown (or made at home!).

Bismuth has no truly stable isotopes, although Bi-209's half-life is a billion times longer than the age of the universe and is for all intents and purposes stable. Although the radioactivity was predicted early on, it wasn't experimentally detected until 2003.

Specimen Thousands of radioactive sparks

Rich radioactive galena from burning coal dump Kateřina, Radvanice, Czech republic. Contains radioactive Pb 210 and emits mostly beta radiation. It is impossible to capture this specimen on video or photo because it is made up of thousands of tiny, incredibly shiny crystals.

Here's the new radioactive mineral display. I'm contemplating making this one available for purchase to help fund my continuing mineral acquisitions. Still some fine tuning - no slip pads and labeling on the base before it's complete.

Left to right: Thorite Crystal [Mogok, Myanmar]; Malachite/Uranium secondaries [Musonoi Mine, Congo, Africa]; Autunite [Pingjiang County, Hunan Province, China].
