When you say that it would be better to buy from other people who extract it, I totally agree, the people who work in this sector have to face many difficulties.The gold metal makes some people lose their reason, greed envelops them in such a way that they even lose their lives, sad but very real.
I bought the Gold Nugget from the person who found a large pocket of Nuggets under a Big Rock... He had a Gift Shop next to the North Fork of the Yuba River in Downieville, California...
