Chalcopyrite Balls - E

"RARE" Chalcopyrite balls cluster from the Tonglushan Copper mine near Daye, Hubei Province, China. 

This has to be the coolest formation I've ever seen. It's a must-have for your collection, not only because it's cool but also due to its rarity. This fun and unique mineral specimen is one you will be proud to display. China hit a small pocket of these amazing little gems earlier this year.
