Erbium



Erbium Turnings
Source:  Donated, Friend's Lab
Purity:  99.95%

These turnings were given to me from a friend's lab.  Once he heard about my element collection, he allowed me to take tiny amounts of his rare earths to help complete the collection.  This metal is surprisingly shiny - I was under the impression that rare earths were a reactive bunch, but this one seems to hold up quite well.
