Tetrahedrite
A variety of Tetrahedrite Group
What is Tetrahedrite?
Tetrahedrite is a more complex mineral, as it contains iron, silver, zinc, and up to 15% copper. It is mined for its copper content, but occasionally heavy silver saturations make it even more desirable. The unique tetrahedral shape of the crystals makes them quite fetching additions to a rock collection.
Uses & Applications
Tetrahedrite has some electronic properties akin to a semiconductor, and is therefore sometimes of interest in a commercial capacity. This mineral is used in wiring, photoconductors, and conductive inks. It is also mined to sell as a collector’s item for home décor, because of its attractive crystalline texture and monochromatic color.
