Bismuth, Medium Crystal (BiB)

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'.

This specimen is about 4cm x 2.5cm x 1.5cm, and has a variety of colors, due to surface oxidation.

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