They will prepare copper or silver jewelry first, and then apply a real gold water to the ornaments, then they will hide the original color of copper or silver ornaments. If they look at the surface, they will find the appearance is exactly the same as the real gold jewelry, so that they will be false. Now. How to distinguish? If it's more violent, just use a needle or a knife to cut it to see if the color inside is the same as the color outside. Of course, in addition to this method, you can also prepare a harder sponge, which can be coated with toothpaste or lipstick, rubbed, and the gold plating on it can also be wiped off. It's easy to distinguish!
The second: Gold Technology
The principle of this method is similar to that of the above method. The biggest difference is that the cost of this method is much higher. Because this is a thick layer of real gold wrapped with gold flakes by extrusion on the surface of copper or silver ornaments, which is particularly time-consuming. Therefore, this method is generally more than 10 grams for jewelry with heavier grams. If it is too light, it will not be cost-effective. Moreover, this method is used to make jewelry with heavier grams It's hard for ordinary people to find out the fake gold jewelry made by this red method, even if it can't be found with a blade or a live fire, but it also has a hole. The fake gold jewelry made by this red method is generally ugly in appearance, large in size, and gives people a feeling of light in grams!
Third: genuine gold adulterated
The real gold is adulterated. As the name suggests, gold is still used as the raw material, and then a large number of copper and silver raw materials will be added In order to increase the number of grams for profit, for example, if you want to make a 10 gram gold, you will prepare 5 grams of gold, and then add 5 grams of copper or silver. This method is very simple, and it is easy to distinguish. As long as you burn it with a lighter, you can know whether it is true or not. Generally speaking, the real gold will not change color when encountering fire, but will be mixed with other materials The phenomenon of discoloration of the golden flowers appears. If you burn them in the same place for 20 seconds, you can see the effect!
The above methods are all made of highly imitated gold. When you buy gold jewelry, you must pay attention to it. You'd better go to some gold shops with good reputation to buy it
