A 40+g sample of Strontium metal in the form of a beautiful and stunning distilled crystal cluster.  This museum grade sample was produced by distillation of the metal and slow cooling of the vapor to grow the beautiful crystals you see here.  The sample is sealed in a quartz dome under Argon to permanently preserve the shiny surface. Purity is 99.9%.  This is a truly unique and one of a kind piece!  Pictures just don't do it justice.
