How to distinguish the authenticity of gold ornaments
1, identified with a needle
Gold has a soft texture and a low hardness. Even if it is made into jewelry, the surface is easy to be scratched. So we can use a needle to slide on the surface of gold. If there are traces, it means it is real gold. If there is no trace and the surface is too hard to scrape, it is fake gold or gold with low purity.
2. Listen to the sound
Real gold is very textured and heavy. If you throw it on the ground, there will be a dull click and it will not rebound. And fake gold or gold with low gold content, the sound of landing is crisp, just like the sound of a steel shovel landing, and some gold will rebound or jump violently.
Step 3 look at the weight
When buying gold, you can also feel the weight of gold. Under the same volume, gold is about twice as heavy as silver, so it will feel flat when held in your hand. And gold or fake gold with copper, lying flat on your hand, has only weight and no feeling of falling.
4. See if it's deformed
Gold is soft, it is easy to deform with a little force, and it has no resilience, so it can only be broken back by manpower. It is difficult to deform fake gold or low-content gold, even if it is slightly deformed by force, it will rebound immediately.
Step 5 use magnets
Real gold will not attract magnets, and many fake gold ornaments will attract magnets by adding metal substances such as aluminum alloy. So when you buy gold jewelry, you can put the magnet in your pocket and try it a little when you buy it. If the magnet is not attracted by gold ornaments, it means it is real gold.
