Gold-covered silver necklace is a necklace used for fraud. There are two cents of gold outside and eight cents of silver inside, commonly known as "gold covered with silver". In fact, it's just a "gold-covered silver" necklace with less than 20 grams of gold.
There is a thick layer of gold outside, so it is difficult to tell the truth from the appearance color. When it burns with fire, the jewelry turns black instead of getting brighter and brighter as gold usually does. See really gold-plated silver, one is the purity of gold, the other is the hardness of gold, and the third is the purity of silver. Some cheap gold-plated silver on the internet is gold-plated with placer gold, not really gold-plated silver.
If the gold plated outside the jewelry is thick, it is difficult to verify the authenticity of the jewelry with a touchstone, and it will only be found if it is broken. However, because the density of silver is only half that of gold, if more silver is added, the weight of fake jewelry will be lighter than that of gold jewelry.
