In the last decade, the price of gold has increased from about 280 dollars per ounce to recent 1,600 dollars per ounce, with a rise of more than 3 times. It was really a gold decade of gold investment.

It has ever been circulated online that fake gold bars with tungsten as its core are likely to appear in the gold market. It is said that these fake can be tested by means of chemistry, weight and X-ray as the density of gold is 19.3 g/cm3 while that of tungsten is 19.25 g/cm3.

Besides, it only cost 50,000 dollars to manufacture a 400-ounce-weight fake gold bar with tungsten core, far cheaper than a pure gold bar with the value of about 480,000 dollars.
