Differential gold requires some 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.
How to identify the silver, the true silver is very soft and easy to scratch. With nails gently, there will be scars. Teach you a simple way to gently draw the jewelry to the lime wall. Black scratches will be left on the wall, rubbing with toothpaste, it will become brighter. The color disciral method. Observe with the eyes, it looks white, luster, fine work, and printed 925 markers on the jewelry, which is high -colored silver jewelry; it looks slightly yellow, rough in workmanship, and is low -colored silver jewelry; poor color is poor; Most of the downed ones are fake silver jewelry. This bending method. Bend the silver jewelry with your hands, soft and waxy, easy to bend and not easy to break; stiffness, or barely move, and some can not even be folded with your fingers.
