<p>[QUOTE=&quot;rmpsrpms, post: 3177638, member: 31773&quot;]I would think that crystallized gold would be fairly pure, correct? One of the interesting things about different regions is that you can identify where the gold came from by analyzing what else is in it. So in theory, unless it is mixed with gold from other sources, you could identify the source from a sample such as a coin. I don&#039;t know how destructive it would be, but perhaps a good XRF machine would work without much damage.[/QUOTE]</p><p><br /></p>
