Bismuth is a semimetal/metalloid that occurs as a native element.  It has a metallic luster, bright silvery color & streak, is soft (H=2 to 2.5), has one cleavage plane, and is relatively fragile/brittle.  This is the principal ore mineral for bismuth.


Bismuth (1.7 cm across) from Wolfram Camp, northern Queensland, northeastern Australia.  Bismuth from this locality occurs in a quartz-rich molybdenite-wolframite-bismuth pipe in altered roof zone rocks of the Elizabeth Creek Granite.  The granite body contains pinkish monzogranites of Pennsylvanian to Early Permian age.
