A sample of Eu metal in the form of a shiny 1in engraved cube sealed under argon in a glass dome. Purity is 99.99%. The metal has an iridescent surface and has the element name, symbol and atomic number engraved on the cube.  You almost never see Eu metal in this form! Please check my Bonanza store for more element samples.  I have almost every collectible element available. Thanks for looking.
