Look at the 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 the golden gold. The so-called green gold is only a silver component in the gold); the dark red yellow color is more than 95%, and the light red yellow yellow 90-95%is 90-95% The pale yellow is 80-85%, the cyan is 65-70%, the color blue with white light is only 50-60%, and the slightly yellow and white are less than 50%. Generally, Qiqing, Eight Huang, and Jiu Chi can be used as a reference. Listening to the sound: The real gold with a color of more than 99%is thrown to the hard ground, which 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. ： 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. Themids: Domestic gold jewelry is all prepared according to international standards, and the killing records, such as "24K" indicate "foot red" or "foot gold"; Those who are lower than LOK can not play the K -printed number according to regulations. Gold used to measure the value of the rest can be traced back to ancient Egypt and ancient Rome. In modern times, it is used as a standard for measuring the value of other items. In the early 16th and 19th centuries, the gold and silver standard system or complexity system widely selected by various emerging capitalist countries was a relatively mature and perfect system.
It if there is a question for purchased gold, it should be tested in a timely manner. The gold jewelry testing agency under the national technical regulatory department is distributed in major cities, and it is easier to detect the composition of gold jewelry. When purchasing gold products such as investment gold bars and gold blocks, they must choose regular merchants who promise to repurchase. They can guarantee the quality of gold. For inspection of gold, the easiest technique is to put gold bars or gold jewelry on the fire for a while to observe its changes. The gold bars with insufficient purity will become gray; and the color of pure gold will be red after the fire is baked. However, this method may cause some damage to accessories.

In daily life, there are some specific methods for the authenticity of the authenticity of the gold jewelry. The introduction is as follows: (1) Fire burning method: "Real gold is not afraid of fire", and the jewelry is cooled through high temperature fire. Gold is still golden yellow and does not deform. This is the saying that the "fire is afraid of real gold". If it turns black, it is not real gold or other metals. (2) Eye viewing method: Gold has dazzling red yellow, and their luster and color are enduring. The lower the color, the worse the color, the "seven greens, eight yellow, nine red, nine reds, "". Gold jewelry with other metals can be recognized from color. (3) ear listening: Listen to sound to distinguish ingredients. Falling the jewelry from the height of naturally, if the sound of "tab" is made, and there is no rhyme and elasticity, it is gold with higher purity. If the sound of sinking rhyme has a long elasticity, it means that it is not high, and the jewelry contains more metals. (4) Hand: It is more weight with your hand. The proportion of gold is 19.3, which is much higher than metal such as silver, copper, and tin. Through a relatively heavy weight, you can identify whether it is faked in other metal gold jewelry, because gold of the same volume is much heavier than silver, copper, aluminum, etc. (5) Teeth biting method: Gold hardness, relatively soft, bite with teeth, there will be traces. Other imitation gold does not have this characteristic, and the higher the color of the gold, the softer.
