    You can use the naked eye to distinguish it by yourself, and the tips for identifying the authenticity of the gold jewelry are as follows:
    1. See the color
    according to the different luster and color of the gold to generally distinguish the pure gold and K gold, real gold, real gold, real gold , Fake gold. The old -fashioned old -fashioned "Qiqing Eight Yellow Nine Five Red and yellow leucorrhea gray pairs of gold" circulating is the purity of the gold.
    2. Seeing the mark
    The domestic gold jewelry must be used as a kill. It indicates that 24K means that the purity is above 99.6%and indicates that the purity is above 75%.
    3. Look at the hardness
    The gold with high color, can leave traces with large head needles or nails. More than 97%of gold jewelry, after twisting two or three times, wrinkles appear at the bending, also called fish scales; about 95%of gold jewelry, it feels hard when bending, and the fish scales are not obvious; about 90%of the golden gold golden gold; The jewelry is very hard when the bending is bent, without fish scales; gold jewelry containing more impurities, bend twice or three times to break; if it is made for raw gold, the bend is broken.
    4. Listening to the sound
    The real gold with a color of 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. The weight of the
    The proportion of gold is 19.3g/cm3. The color and proportion have a large relationship. When the proportion is close to 19.3, the higher the pure gold. Looking at whether it is commensurate with the size of the size, the shape is large and lighter may be adulterated. But generally in the hands, if you feel slightly sinking, you can perceive the real gold jewelry, which shows that the gold body is small and heavy. You should be vigilant for the stupid and light jewelry, and carefully discern whether for fakes or semi -fakes.
    6. Try soft hard
    The higher the color of the gold jewelry, the softer, and the more elasticity. The real gold bite or the needle will have light marks. Low -colored steel is hard; those with heavy mixes are elastic, crispy and easy to break. The pure gold is soft, and it is generally not used to make embedded jewelry. Therefore, all inlaid gold jewelry claims to be 24K and there must be fraud.
    7. Scraping porcelain plate
    In finding an unbuused porcelain plate. If not, you can buy a piece of porcelain at home in the home improvement store. Scrape the porcelain plate with a golden device. If the black scratch is left on the porcelain plate, your gold ware is not a real gold. If the scratch is golden, it is true gold.
    This can make the fake golden shape reveal, but your gold ware may be scratched.
    8. The nitric acid test method
    The gold ware is placed in a small stainless steel container, a drop of nitric acid is on the goldware to observe the reaction. If the acid is green, then this golden device is either made of ordinary metals or gold plated. If it is golden, it is gold -plated copper. If it presents milk, it is gold -plated silver. If there is no reaction, then this golden device is true.
    This nitric acid test is a good way to distinguish the authenticity of gold, but because nitric acid is not easy to obtain, and it is also dangerous to operate at home, it is recommended that you give it to the jewelry dealer to do it.
