 More studies were performed in 2008 and 2009 by a team consisting of members from the National Institute for Nuclear Physics and Engineering, Romania, the National History Museum of Romania, and the BAM Federal Institute for Materials Research and Testing, Germany.Researchers compared the gold composition, examining the trace platinum group elements, Tin, Tellurium, Antimony, Mercury, and Lead and comparing them with the corresponding elements of natural gold from Transylvania.This was done since these trace-elements are more significant for provenancing archaeological metallic-artifacts than the main element components.
