Chalcopyrite

Purchased 2/10/2014 at a gem and mineral show for only a few dollars. Sizewise, this is around the same size as the average nail polish bottle. This piece is from the Zacataecas, Mexico area of the world. To be honest, I found it the prettiest piece they had in the section and I loved the blues and purples in it.

For a bit more info on this, this site is helpful or you can find it on wikipedia or elsewhere if you don't trust outgoing links. ^_^
