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.
