Buy gold on Taobao, it is recommended to go to the mall. There is a guarantee point.
The identification of gold requires certain experience. Here are only some identification methods.
(1) See color: the higher the purity of the gold jewelry, the deeper the color. If there is no gold medal, you can determine the general color according to the following color (based on green gold. The so-called green gold contains only silver ingredients in gold); dark red yellow color is more than 95 %, light red yellow 90-95 % The pale yellow is 80-85 %, the cyan is 65-70 %, and the white light is only 50--60 % white light. The slightly yellow and white are less than 50 %. Generally, Qiqing, Eight Huang, and Jiu Chi can be used as a reference. (2) Type weight: The proportion of gold is 19.32, which is more important than metal such as silver, copper, lead, zinc, aluminum. The volume of gold is more than 40 % heavier than the silver, 1.2 times heavier than copper, and 6.1 times heavier than aluminum. The gold jewelry should have a feeling of sinking in the hand, and the fake gold jewelry feels lightly. This method is not suitable for gold jewelry inlaid.
(3) Look at the hardness: pure gold is soft and low. It can draw light marks with nails. Teeth bite can leave tooth prints. High -colored gold jewelry is low and soft, with copper with copper, contains copper containing copper, contains copper containing copper The harder, the harder, the bending method can also test the hardness, the pure gold is soft, it is easy to bend, the lower the purity, the less likely to bend.
(4) Listening to the sound: Real gold with a color of more than 99 % throwing it 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.
(5) Burning with fire: The jewelry will be burned red (do not melt the jewelry) with fire (do not melt the jewelry), and observe the color change after cooling. Dark or different degrees of darkness is not pure gold. Generally, the lower the color, the stronger the color, and the darkens are all, indicating that it is a fake gold jewelry.
(6) Seeing the mark: Domestic gold jewelry is allicized and prepared according to international standards, and the killing records, such as "24K" indicate "foot red" or "foot gold"; The word "18K" is marked, and those who have a lower color are lower than LOK. At present, illegal elements are commonly used to manufacture fake cards and imitation stamps in the society. They use rare gold, Asian gold, and even brass to impersonate real gold. Therefore, the identification of gold jewelry must be comprehensively determined according to the sample to determine the true and false and the quality of the real.
24K gold jewelry recognition method: K gold refers to gold and copper according to a certain proportion of gold, according to the formula of 24K formulas.

It can become a thousand -foot gold Thousands of gold is more pure, and the purity reaches 99.99%; the purity of the foot gold is 99.95%, and the price of thousands of gold is more expensive. The identification method is the following . View the mark The national standards, precious metal jewelry should be produced, manufacturers, materials, and content marks, and unqualified products are unqualified products. If a quality problem, quality inspection agencies may be given inspection and judgment according to the mark. Consumers should purchase the brand they need and the gold jewelry of different gold content according to the mark. . Sensory inspection method: 1.
