I bought a ring in China gold today. There is no steel seal of Chinese gold on the inner wall. The inside is printed with many patterns and the word "Fu". Is this lucky character its steel seal?

    Gold jewelry generally includes full gold, thousand gold, K gold, etc., and the marks are also different:

    1. Full Gold: that is, the gold content is not less than 990, and the marks are "full gold", "gold 990", "G990", "au990"

    2. Thousand gold: that is, the thousand fraction of gold content is not less than 999, and the marks are "gold 999", "g999" and "AU999"

    3. K gold: that is, color gold, refers to precious metal with gold content from 8K to 24K. The gold content of 18K gold is 750 ‰, and the marks are "750" and "18K". The gold content of 14K Gold is 585 ‰, and the marks are "585" and "14K"

    maintenance methods for gold jewelry

    1. The chemical substance of cleaning essence will change the color of gold, so you should take off the gold jewelry before cleaning

    2. Avoid direct contact with perfume, hair gel and other highly volatile substances, otherwise it will easily lead to the fading of gold ornaments

    3. When swimming, take off the gold ornaments to avoid chemical changes on the surface after touching the seawater or pool water

    4. Wrap it with flannelette and put it into the jewelry box to avoid mutual friction and damage

    5. Gold is soft and easy to deform, so don't pull necklaces and other accessories to avoid deformation

    6. Pure gold jewelry will produce chemical reaction when encountering mercury, and white spots will appear. When cleaning, it can restore its original color as long as it is roasted under an alcohol lamp for a while

    7. Gold ornaments often lose luster due to dirt and dust after wearing. At this time, just put the gold ornaments in neutral detergent, soak them in warm water and clean them, then take them out and wipe them dry

    The mark of Chinese gold jewelry is Zhongjin
    China gold is mainly engaged in the survey and design, resource development, product production and sales, and EPC of non-ferrous metals such as gold, silver, copper and molybdenum. It is a comprehensive large-scale mining company integrating geological exploration, mining, mineral processing and smelting, product refining, processing and sales, scientific research and development, and engineering design and construction
    pure gold refers to 24 karat gold, which means its gold content is 100%. But there is no 24K gold in the world. Therefore, if there is gold marked with "24K gold" or "pure gold" on the market, it is not true
    the content of pure gold in decorative gold is called "gold position", which is karat in English, so it is called K gold. Generally speaking, pure gold is 24K, that is, the theoretical gold content is 100%
    the gold content of 22K is 91.6% (22 / 24 = 0.916)
    the gold content of 20K is 83.3% (20 / 24 = 0.833)
    the gold content of 18K is 75% (18 / 24 = 0.75)
    the gold content of 14K is 58.3% (14 / 24 = 0.583)
    the gold content of 12K is 50% (12 / 24 = 0.5)
    the gold content of 10K is 41.6% (10 / 24 = 0.416)
    the gold content of GK is 37.5% (9 / 24 =0.375)
    the gold content of SK is 33.3% (8 / 24 = 0.333)
    In China, 18K is generally used to inlay jewelry, so the fastness of inlaid jewelry is relatively high. Karat refers to an alloy in which gold and other metals are mixed together. Karat is the unit of measurement of karat, which divides pure gold into 24 parts. According to the gold content in jewelry, it is divided into different K-gold. Therefore, 24K refers to pure gold. For example, the gold content of 18K is 18 / 24 = 75.0%. Because the gold content of 18K is 75.0%, it is also called 750.
