Some gold shops also launch free jewelry appraisal activities every year. Gold shop inspection is equivalent to an experience service, which helps you to see clearly the seal, gold content, color and weight of gold jewelry. If the gold shop where you identify gold is different from the one where you buy gold, there is usually a charge. But this charge also depends on the relevant situation. If you just ask the service staff at the counter to take a look at it for you, you don't need to use any instruments. Generally, there is no charge, but as long as you use the instrument, you will be charged.
There is no need to doubt whether the counter service personnel can judge the authenticity of gold. After all, they sell gold, so they have a certain understanding of gold, and sometimes they tell guests the identification method of gold authenticity.
How to identify gold
1, the authenticity of gold can be identified by sound. When gold is thrown to the ground, real gold will hear a dull sound and there will be no signs of rebound, while fake gold will hear a crisp sound and there will be signs of rebound.
2. You can also tell the true from the false according to the color. If it is high-purity gold, the surface will be red and yellow, and it will shine brightly under the irradiation of light, while fake gold is doped with many other metals, which leads to its dull luster.
Gold can be identified by logo. Real gold generally has relevant marks, the most common ones are au999 or 999 gold, and some even have the manufacturer's marks, while fake gold usually does not have these marks.
