A 74+g sample of Bismuth metal in the form of a beautiful and stunning crystalline dome sample.  This museum grade sample was produced by melting the metal onto the inside walls of the glass while slowly cooling, allowing the beautiful crystals you see here to grow.  The sample is sealed in a quartz dome under Argon to permanently preserve the shiny surface. Purity is 99.99%+.  This is a truly unique and one of a kind piece!  Pictures just don't do it justice.
