  1. As long as you buy authentic gold Liufu, it should be genuine.
    1. Six Football Gold 999 is a kind of pure gold, with a gold content of 99.9%.
    This has not yet reached 100 % purity gold. 999 gold is the highest value of jewelry in the market circulation. It is usually processed from welded welding processes.
    2. Six Football Gold 999 belongs to pure gold. Foot gold 999 refers to gold with a gold content of 99.9%.
    Theoretically the gold content of pure gold is 100%, but due to the influence of the gold purification process, the gold content of more than 99.6%of the gold content is actually called pure gold.
    The gold 999 is a high -colored gold, which is red yellow, and the texture is very soft. You can use your nails to draw traces on the surface. And after bending several times, obvious fish scales will appear in the bending part, which is not available for low -colored gold.
    Thenally 9999 gold than 999 golden purity, this is the highest value of jewelry in the market circulation. It is usually made of "no welded welding process". Red yellow, the texture is very soft and easy to deform.

    How to identify the authenticity of gold and silver jewelry of gold and silver:
    . Use physical knowledge to measure the density of gold and silver jewelry to identify the authenticity of gold and silver jewelry.
    The method is as follows:
    1. Install the jewelry to be tested into the amount of 200 ml of aquatic solution, the mm of the liquid level rises, that is, the volume of the water discharge of the jewelry is the volume of this jewelry. Here we assume that the size of the jewelry is V cubic centimeters. (Note 1 ml = 1 cubic centimeter).
    2. Use Tianping weighing to measure density jewelry quality. Put the jewelry in the balance of the balance, place an appropriate amount of method code on the right disk, and adjust the whole code to balance the balance. The quality of the jewelry is the number of grams of the method of the method of the method. Here we might as well assume that the quality of the jewelry is M gram.
    3. The density of this jewelry is M/V. Calculate the specific value. One cubic centimeter of real gold weighs 19.3 grams, and one cubic centimeter of silver weighs 10.5 grams. If you compare it, you will know the authenticity.
    . Use the method of fire to identify the authenticity of gold and silver jewelry.
    1. "Real gold is not afraid of fire" and burn the gold jewelry in the fire. After cooling, if the surface of the jewelry is still golden yellow, it is real gold. If it becomes black, it is fake gold.
    2. The silver jewelry does not change after the fire is burned. If the silver is low, it will turn black.
    . Use chemical knowledge to identify the authenticity of gold and silver jewelry.
    1. Gold jewelry, take 1: 3 nitric acid on a drop of object, stay for half a minute, if it is foaming, wipe it with cotton or white paper, if blue -green, it must be faked by copper or copper alloy; Nitric acid does not show the color and the color is both tough and quite hard.
    2. Silver jewelry, still take a drop of 1: 3 nitric acid, put it in light salt water in half a minute, if there is white turbid, it can be regarded as a real product.

  2. Whether it is investment, gifts or home biography, gold has always been sought after. In recent years, the demand for gold has increased steadily, and more and more people buy gold jewelry. However, is the gold you bought "real gold"?
    Recently, the Jinhua Market Supervision Bureau of Zhejiang Province launched a special supervision and random inspection of the quality supervision of gold jewelry products in the circulation field. The batch of unspeakable rates reached 43.75%. The brands involved in unqualified products in this sampling inspection include Golden Liufu, Saturdays, Lao Temple, Chinese Jewelry, etc.
    The results showed that one of the products involved unqualified purity. The purity indicates the minimum quality content of precious metal elements. The unqualified purity of this batch is the purity of the product label that is inconsistent with the actuality. The purity displayed on the product label is 24K, but 24K refers to the gold with a theoretical purity of 1000 ‰. In reality, it cannot achieve. The reason for the unqualified purity may be that the merchant is not familiar with the relevant standards, but it is also suspected of existing the subjective intentional intentional intention to make a false publicity and exaggerate the gold content.
    34 batches of products involved unqualified logos. Gold jewelry logo is the main channel for consumers to know product information and an important source of consumers' right to know. The national compulsory standards have clear requirements for it, including marks, labels and other logo. Unqualified imprints are information such as inconsistent marks and labels, unclear marks, and lack of manufacturers' code or purity. The label is unqualified, mainly the nameless name, the name of the name, the non -indicated material or the purity, the lack of product standard number or the product standard number is not related to the product, the lack of the name of the manufacturer (or sales enterprise), etc. Lack of addresses (or sales enterprises) address, product quality inspection certificates, and necessary Chinese warning descriptions on other logo or labels, and the necessary Chinese warning descriptions, etc. The reason why the product is unqualified in this sampling is that the identification is unqualified.
