How to distinguish between gold and gold

Recently, there has been a kind of 'sand gold' on the market, which is golden and heavy, but in fact there is no gold in it. Meilong Town, Haifeng County, Guangdong Province, is a professional jewelry processing town, known as the "jewelry capital of China".

According to the person in charge of a local jewelry factory, the wholesale price of sand gold jewelry varies from a few yuan to tens of yuan according to different specifications, styles and weights. Not only their color and texture are very similar to real gold, but also their weight is almost the same. When they are retail, they can definitely confuse the real with the fake.

Many jewelry factories in the town do this business. A net red can sell 100000 pieces. A staff member of the appraisal institution told reporters that they can issue an appraisal certificate for sand gold jewelry to prove that it is real gold.

If there is a large amount of testing, the testing fee can also be preferential. If there are more than 100 pieces, 1.5 yuan per piece. As for where and how businesses use these identification certificates, they don't care.
