Misiones Argentina: mines of precious stones

This trip would be probably the most breathtaking for the women. To stay between big big "mountains" of precious and semiprecious stones... My God, is it possible? Oh yess, it's perfectly possible if you visit this province of Argentine, Misiones. It's a kind of corner between 3 countries: Argentina, Brasil and Paraguai. There are so many interesting places there, I just wrote about the waterfalls Iguazu. There are interesting ruins of the "town" of Jesuites and -these incredible places. I found this video in YouTube and think it's more clear then all the words.
