I bought a collection last year from Metallium. It is a set of lanthanide-series rare-earth metal element samples.
The video shows the natural fragility of these metals. This set has been kept in a mostly dark room in arid Las Vegas, Nevada. The metals have never been taken out of their vials.
Some of the metals have discolored but it is hard to compare with how they originally looked when I bought them because I did not photograph them at the time. Rookie move. The samarium exhibits the most deterioration, some of it turning to powder.
I had to take the photos through the glass and plastic vials of the samples and in some cases, through a plastic bag as well.
People are always interested in seeing this collection, even geologists and professors at University Geosciences Departments. These metals are rarely seen.
This is an unsponsored video, I paid for my set and would do so again. This is Metallium’s website.
Here’s a longer version of the video, giving more time to look at the samples.
