5 thoughts on “How to use a simple method to judge whether it is gold!”

  1. When weighing, the real gold feels like falling on the hand, and the fake is very light; Try texture and burn on fire. The true color will keep the original color, and the false color will change; When measuring the magnet, the real gold will not be attracted by the magnet, and the imitation will be attracted by the magnet. The weighing method can distinguish the authenticity of gold because the same volume of gold is usually heavier than other precious metals. The ratio of gold to other metals is about 19:32. When you hold it in your hand, the real gold should feel like falling, while the imitation gold is light. The easiest way to identify gold by testing its texture is to identify gold and test its texture. Real gold fears no fire. Put the gold on the fire for a while, the real gold will keep its original color and will not change color, while the imitation gold is easy to oxidize and change color once burned
    extended data:
    1. The simplest method to identify gold is magnet test, which can also be used to identify gold. Gold is a non-magnetic metal. When the magnet is placed on the gold, the real gold will not be attracted by the magnet, while the imitation gold will be attracted by the magnet in daily life. There are some simple and easy methods to identify the authenticity of gold jewelry, as follows: fire burning method: "real gold is not afraid of fire". After the jewelry is fired and cooled at high temperature, the gold is still golden yellow and does not deform. This is the saying that "fire fears real gold". If it turns black, it is not real gold or other metals. Visual inspection: gold has dazzling red and yellow. Their luster and color last for a long time. The lower the color, the worse the color, which is often called "seven green, eight yellow and nine red". Gold jewelry misnamed with other metals can be identified from its color. Ear listening: listen to sounds and identify components. If the jewelry falls naturally from a high place and makes a "click" sound, whether there is rhythm and elastic sound, it is high-purity gold. If the tone is deep, the rhyme is long and the elasticity is large, it means that the fineness is not high, and the fineness of other metals in jewelry is more. Manual weighing method: weigh by hand. The proportion of gold is 19.3, which is much higher than that of silver, copper, tin and other metals. Through weight comparison, we can distinguish whether gold jewelry is counterfeit with other metals, because gold of the same volume is much heavier than silver, copper, aluminum, etc. bite method: gold is low in hardness and relatively soft. If you bite with your teeth, there will be traces. Other imitation gold does not have this characteristic, and the higher the fineness of gold, the softer it is
    2. Check the appearance and check the official logo of gold. They are generally engraved with 999 or 990, or 10K, 18K, 22K, 24K. Do not consider below 10K, because the gold content is too low. If you look through a magnifying glass, you will see more carefully. Ancient gold jewelry does not have obvious official purity marks. Of course, fake gold jewelry will also have official signs, which need further inspection. Look for obvious discoloration. Check the worn area of the gold surface, usually at the edge of the gold product, and check for discoloration there. If the gold color gradually disappears and becomes another color, the product is only gilded

  2. Folk earthwork: if you bite with your teeth, the bite marks are gold. Or it can be judged to be gold by burning it and turning it black. But I suggest you go to the gold jewelry store to do an appraisal!

  3. In daily life, there are some simple and easy methods to identify the authenticity of gold jewelry, which are introduced as follows:
    (1) fire burning method: "real gold is not afraid of fire". After the jewelry is cooled by high-temperature fire, the gold is still golden and does not deform. This is the saying "fire is afraid of real gold". If it turns black, it is not real gold or other metals are mixed
    (II) eye observation method: gold has a dazzling red yellow color. Their luster and color are enduring. The lower the fineness, the worse the color, that is, people often say "seven green, eight yellow and nine red". Fake gold jewelry with other metals can be identified from the color
    (III) ear listening method: listen to the sound and identify the components. If the jewelry falls naturally from a high place, it will be high purity gold if it makes a sound of "rattling" without rhyme and elasticity. If the sound is long and elastic, it means that the fineness is not high, and the fineness of other metals in the jewelry is more
    (IV) hand balance method: compare the weight by hand. The specific gravity of gold is 19.3, which is much higher than that of silver, copper, tin and other metals. By comparing the weights, we can identify whether other metals are used to fake gold jewelry, because gold of the same volume is much heavier than silver, copper, aluminum and other metals
    (V) tooth biting method: gold has low hardness and is relatively soft. If you bite with your teeth, there will be traces. Other imitation gold does not have this feature, and the higher the fineness of gold, the softer it is,.
