Gold crystal looked too big to be real
April 11 , 2014
A single gold crystal, about the size of a golf ball, was found in Venezuela decades ago and the owner provided the 217.78-gram nugget to geologist John Rokovan so he could determine the crystal's authenticity.
The Miami University professor mentioned that he had never seen a structure this big before and took the pieces to a laboratory in order to employ neutron diffractometry. He found that three of the four pieces, including the big one, were single-crystal and further analysis will "also provide an understanding of how the rare pieces may have formed before they were slightly deformed while being washed down in ancient stream sediments."
