Bismuth, small Crystal

Bismuth is an elemental metal, found on the periodic table of elements.  Curiously, it rarely occurs in nature as a metal; generally being found in Oxides, Sulfides, and complex minerals.  Once refined, crystals like this can be grown.  We like to describe them as forming in shapes similar to a 'step pyramid'.

These specimens have a maximum dimension of under 1inch, and have a variety of colors, due to surface oxidation.

Single small crystal will fit in a Small USPS Priority Mail Flat Rate box.  But, could easily be packed with other items.
