Although platinum is identified by karat marks but stamped with "PT" or "plat" in the U.S. and "950" or "PT950" in Europe, other alloys are coming on the market. Dave Neuberg, Chief Executive Officer for Karat Platinum, put in a request to the Federal Trade Commission (FTC) to accept new technology for producing 585 platinum and 415 copper and cobalt product, 585 Plat.0 PGM, which will be stamped 585Pt.415Co.Cu (http://www.ftc.gov/os/comments/jewelryplatinum/517683-00054.pdf. ). This alloy stamp means the Karat Platinum is 58.5 percent platinum, and 41.5 percent copper and cobalt.

The Diamond Guy Diamond Cutters International refers to this controversy as platinum doping
