A 20g sample of Cerium metal in the form of shiny pieces sealed in an ampoule under argon. Purity is 99.5%. Ce metal is very difficult to find in such a shiny state and the ampoule looks beautiful and will remain shiny forever. Please note that there is always a chance the ampoule can break during shipping, therefore the package will be fully insured against damage. The price includes free priority mail shipping within the US. Please check my Bonanza store for more element samples. I have almost every collectible element available. Thanks for looking.
