You can take it to the gold shop to identify the color. Gold shops are usually identified by being divided into two parts.

Identify adulteration:

1. Does gold have white highlights?

Cut the gold bars or jewelry with scissors, and observe the section with a magnifying glass. If you see white bright spots, because gold and iridium can't blend together, it means that gold is doped with iridium.

2. Specific gravity measurement:

First, measure the weight of a pure gold bar with a balance, then put the gold bar into a measuring cup and pour water to drown it. Then put the detected gold bars into a measuring cup and observe whether the scale of water rises or falls. As long as there is a change, it means that gold bars are not pure gold. But if it is gold jewelry, this method is not applicable, because there is air in gold jewelry.

Extended data

There are few fake cases of gold, including sterling silver, and silver is also a veritable precious metal. It is a very extravagant situation to pass off silver as gold. With the rebound of gold prices in the past six months, social capital loans have increased, and many cases of gold bar fraud have been discovered.

Lawyer Sun of Guangdong Huajing Law Firm believes that precious metals have a high melting point, so it is extremely difficult and costly to fake with gold and silver. Similar phenomenon should not be a single accidental fraud, but an organized, premeditated and large-scale vicious fraud by illegal institutions, which has seriously violated many criminal laws and should be severely punished.
