1 thought on “Which three numbers indicate the thousands of gold in gold”

  1. 1. What is thousands of gold?
    The gold content of not less than 999 ‰ is called thousands of gold, which is the highest value of jewelry named names. It is often called thousands of gold, 999 gold, GOLD999 or G999. Use numbers 999 to represent the thousands of gold in gold, commonly known as "three nine golds".
    The gold content is not less than 990 ‰. It is often called "foot gold", "990 gold", "GOLD990" or "G990", commonly known as "two nine gold".

    . What is the difference between foot gold and thousands of gold?
    Thousands of gold must be foot gold, but foot gold is not necessarily thousands of gold. Although Foot Jin and Qianzujin are only one word, there are still many differences, which are mainly reflected in the following three aspects:
    1. In terms of gold content
    99, and the gold content of thousands of gold is relatively taller, up to 99.9 percentage. Therefore, there is still a significant gap between the gold content of the two.
    2, price.
    Because of the different gold content, it also leads to the difference in price. Because the gold content of the sufficient gold is not as high as high, the price will be relatively low.
    3, in terms of color
    . The other reflection of the color is called purity. Generally speaking, the purity of gold rises, and the color will be deeper. The purity can be reflected by the gold content. The higher the gold content, the higher the purity. Therefore, the color of the foot gold is not as deep as the color.

    . How to choose a good -footed gold jewelry?
    The people commonly used in cooked gold in the cooked gold, that is: weighing weight, looking at color, discussion rhyme, softness, and acid.
    The gold density is significantly greater than common metals such as copper, silver, lead, and zinc. Compared with the same volume of silver and copper, it weighs about twice as much as possible. If the items are gold, it feels heavy.
    Thousand -footed gold has its unique golden brown luster (low color exception). Pure gold is shining with dazzling light under the strong light. This is not available in other metals, including copper inside.
    The thousand -footed gold with a high color, no rhyme and elasticity when the sound is thrown in the ground, and the sound quality of the low -footed gold is slightly brighter, and when the copper product is thrown on the ground, the sound is loud. Therefore, according to the sound of the knocks, we can help us distinguish between common metals and gold.
    Thousand -footed gold has the characteristics of good ductility and small hardness. Pure gold is folded and soft, and the bronze strips are laborious. Or use large head needles (nails are also fine). If the force is not large and the traces are obviously golden, the copper is slightly stronger and the traces are slightly worse. It is only difficult for gold bars, gold coins, bricks, and the like. The authenticity of the first judgment of gold is also effective, but it is necessary to use different orientation of the inspection objects. If the color of several grinding roads is obviously different, adulteration is undoubtedly mixed.
    Is do not believe the identification method of the above -mentioned cooked gold, you can only use nitric acid, that is, the nitric acid point its grinding road to determine its true or false.

    The above is the introduction of thousands of gold. Finally, remind everyone not to follow the trend blindly, just choose according to your own economic conditions.
