It is best to buy gold through regular channels. Now online channels are developing rapidly, but mixed fish and dragons are not false, but there will be certain risks. It is okay to buy it in Chinese gold specialty stores or through banking channels. Of course, the relative handling fee for banking channels is higher.
This can be divided into pure gold, K gold, real gold and fake gold according to the different gloss and color of the gold. That is, gold is red (yellow -red), and the color is more than 95 %; the positive yellow color is about 80 %. The blue and yellow color is about 70 %; the yellow color is slightly gray and the color is about 50 %.
Therefore, there are tactics "seven green eight yellow nine five red, yellow leucorrhea ash pairs of gold". For a long time for gold jewelry, there will be a saying that "copper turns green, silver turns black, and gold will never change color".

The method of identifying golden and false:
1, see color
You can generally distinguish pure gold, K gold, real gold, fake gold. The old -fashioned old -fashioned "Qiqing Eight Yellow Nine Five Red and yellow leucorrhea gray pairs of gold" circulating is the purity of the gold.
2, listening to the sound
When a high -colored gold is thrown on the hard ground, it will make a tap sound, there is no rhyme or elasticity. The fake or low golden sound is crispy but no dullness. Generally, the sound of "Dangdang" is emitted, and there are surplus sounds.
3, weight
The density of gold is larger than other metal silver, copper, lead, zinc, aluminum, etc. Even more, real gold should have a sense of sinking, and fake gold jewelry feels light.
4, test hardness
The pure gold is relatively soft. The higher the gold content, the softer, and it is easy to bend with your hands, but its toughness is good and it is not easy to break. Conversely, the lower the gold content, the harder it is. It needs to be bent with greater strength, and it is easy to break. When scratching with hard things, scratches are not obvious.
5, density
The density of gold is 19.32 grams / cubic centimeter, which is about double the same volume of silver, lead, and tin. Available formula: The mass (gram) of a certain gold jewelry (gram) is equal to density than the volume (cubic centimeter) of a certain gold jewelry (cubic centimeter). Seeking the density of the gold jewelry measured, the density is about 19.32 grams / cubic centimeter, it is pure gold or relatively pure gold, otherwise it is a non -pure gold or color difference gold.
