Gold Alloy Forensics Leads to Source in Cornwall, England One of the most interesting aspects of this discovery is the nature of the gold used to make the jewelry piece. Chemical analysis revealed that the gold was a naturally occurring alloy. Its chemical composition included 20 percent silver, between one and two percent copper, and smaller quantities of platinum and tin. Gold alloys that have been mined but not processed have unique chemical “fingerprints,” which often allows researchers to trace their origins to specific geographical areas. When the archaeologists traced this particular alloy to its source, they were completely surprised! It seems this alloy’s “fingerprint” matched that of gold that comes from the Cornwall region in the southwestern United Kingdom. More precisely, this gold likely would have been panned from the Carnon River , which at one time produced significant quantities of this most desirable precious metal.
