Just like buying anything unique it comes down to the quality of the paper trail

This is a good answer, but I don't know if I accomplish the testing you describe.  How would I find a lab that can do the testing?

@John Can you give an example of a trustworthy paper trail for trinitite?

@Craeft A certified report from an accredited testing lab, or original government collection paperwork and a trail of receipts, collection photographs...

@Craeft: [This](https://www.gammaspectacular.com/phpBB3/viewtopic.php?t=755) might be of interest. As for a lab for testing, try an online search. Most of the ones I've found appear to be associated with universities.

@Fred That link includes a link to where the author bought the sample.  I suppose it would be safe to buy from that dealer?

# Avoiding fake trinitite

(Asked by: username_0 on 2021-05-02)

I would like to get some [trinitite](https://en.wikipedia.org/wiki/Trinitite) for my rock and mineral collection. The problem is that there is apparently a lot of fake trinitite for sale in the internet.

How do I avoid the fakes, and be sure I purchase real trinitite?

All radioactive elements have a half life. The radioactive elements produced by the Trinity Test on 16 July 1945 are also well know. To increase the confidence of testing, the amount of each radionuclide in each sample would need to be detected and compared with the expected amount that would be in true Trinitite given the elapsed time since 16 July 1945.
