The identification method is as follows: (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 marks. High -colored gold jewelry is low in color. 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: Throwing the real gold with more than 99 % to throw 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: Burn the jewelry to burn red (do not melt the jewelry) with the fire (do not melt the jewelry), and observe the color change after cooling. The degree of darker 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 all prepared according to international standards, and the killing records, such as "24K" indicate "foot red" or "foot gold"; 18K gold, "18K", indicate "18K" Words, those who are lower than LOK, can not play the K -printed number according to regulations.
Differential gold requires some experience. Here are only some identification methods.

(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 make 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 color of the color.
The above is only available to determine the gold with too much fake color. If you want to judge the difference between thousands of gold and sufficient gold, it is difficult. The difference between 0.9999 and 0.9990 in 1 gram of gold. There must be instruments to distinguish.
The methods commonly used in life are: 1, color method: observe with the eyes, look white, shiny, work finely, for high -colored silver jewelry; poor color, no gloss Most of them are fake silver jewelry. 2. Bending method: Lightly folded silver jewelry with your hands, easy to bend and not easy to break; stiff and barely folding color is low; It is not lighter, and it is easy to break. 3. Nitric acid identification method: Use glass rod to drop the nitric acid at the mouth of the silver jewelry, which is brown rice and slightly green. It has a dark green and black color. 4. Throwing method: Throw the silver jewelry from top to bottom on the table. The bouncing is not high, and the sound is smooth as a high -colored silver jewelry; Or low -colored silver jewelry.
1 Looking at the color, gold is yellow with yellow. This means that if the gold contains insufficient gold, the color will not be the same. The gold density is not high. The items should be heavy. 3. Seeing that the chemical reaction gold will not change color, not afraid of burning. Don't pinch it with your hands when you buy it.
The first look at the density, the second is burning, and the third is weighing. Be sure to keep the ticket when buying. Pinching with your hands, soft is the truth
Put it in dilute hydrochloric acid or dilute sulfuric acid. If you are bubble, you will definitely be greasy The bites that you can't bite with your teeth must be fake silver gold abbreviated.
