Method for distinguish gold from real gold:
1. Look at the official symbol: it depends on the official symbol to distinguish the authenticity of gold. In the process of buying gold or jewelry, the store will stick the official logo, which will indicate the purity and carat number of gold. If it is not marked, it means that gold is fake.
2. Fading: To identify the authenticity of gold, you can observe whether it fades. In the process of wearing gold jewelry, there will be wear, but the worn gap still shows the color of gold, which means it is true, but if the worn gap shows other colors, it means it is false.
3. Whether there are bite marks: To identify the authenticity of gold, you can bite gold with your teeth. Generally, real gold is bitten with teeth, and there will be bite marks. The higher the purity of gold, the deeper the bite marks. But some gold-plated lead has low hardness and bite marks, so this method can only distinguish most gold.
