Look up Tungstent Gold. Here is what it looks like when you open it up. So instead of being pure gold all the way through the gold bar. You have this.

There's a company in China selling Gold Bars made of gold plated tungsten that advertises large quantities for sale to nations and hints at replacing their gold stocks with look alike tungsten bars and that no one will know the difference. . . they also sell tungsten Double Eagle $20 gold coins. . . with the exact weight guaranteed to look just like the "real thing." I posted an article on it several years ago on Freerepublic with a link

.

There was an article just last week about some phony gold bars being traded as real in New York. Those faux gold bars are merely 100% tungsten with a 24K (100%) gold plating. . . or sometimes with a 1mm to 2mm surface casting of real 24K gold to pass a preliminary scratch test.

You can alloy Gold with tungsten and have a legitimate 18K gold so long as the gold content is 75% gold and 25% tungsten.
