What is Pure Gold? Is there any pure gold?

The gold content is not less than 1,000 parts of gold, which is the highest value of jewelry fineness in the market circulation. But it is not included in the national standard, and the imprint is 10,000 pure gold, gold, or. **Jewelry imprints include manufacturer code, material, and purity, such as:

X Gold 990, X Au990, X Pure Gold, etc. Among them, the letter X is the manufacturer code. When using different materials or different purity *** to make jewelry, the material and purity should be indicated separately.

When the jewelry cannot be printed because it is too thin or too small, etc., it should be accompanied by a logo containing the content of the imprint. With gold content as raw material, the jewelry processed by the "solderless welding process" has no electroplating and no solder, the overall quality is consistent, and the product fineness has all reached the highest jewelry. Basic Introduction:

**The purity of the product is called "finished" or "fine". Theoretically, we call 100% gold 24k; Therefore, the calculation method is 100 24 (the national standard in parentheses): the national standard GB11887-89 stipulates, per K (the abbreviation of English carat, German karat, often written"k"The gold content is, 9k k = 100% 24 * 14 = for the convenience of identification, set it at k k = 100% 24 * 22 = for the convenience of identification, set it at 100% gold in theory to be called 24k gold, but in reality there can be no 100% **, so China stipulates:

The content of the above (containing ** can be called 24k gold. These kinds of K gold content are the general specifications of jewelry, and the state stipulates that ** jewelry below 9K cannot be called ** jewelry. Pure gold:

The gold content is not less than 1,000 parts per thousand, which is the highest value in the naming of jewelry fineness. The imprint is pure gold, gold, or. Thousand-foot gold:

The gold content of 1,000 parts is not less than 999 called pure gold. The imprint is "Thousand Pure Gold", "999 Gold", "AU999" or "G999".

The logo and jewelry imprint should contain the manufacturer's code, the name and content of the material. The appearance quality is mainly the inspection of the specific process quality such as the overall shape and processing quality of the jewelry. The weight of jewelry, gold jewelry is calculated according to the weight and processing fee, the weight of jewelry is one of the important indicators, according to the standard The unit of measurement of jewelry weight is grams, and the tolerance of a single piece of gold jewelry is.

Gold content, the gold content in jewelry is an important indicator of its quality. There are many ways to test gold content, which can be divided into chemical analysis methods and instrumental analysis methods. According to whether the jewelry is damaged in the detection process, it can be divided into non-destructive testing method and destructive testing method, and the daily inspection of the jewelry quality supervision department is generally based on non-destructive testing method, density method combined with X-ray fluorescence spectroscopy, electron probe and other large-scale instrument analysis.

Market supervision and random inspection are mainly destructive testing, and the fire assay method is a national testing method for determining the gold content in jewelry. The latest revised version of the standard will be implemented on May 4, and the most important thing is to remove the standard of pure gold, and the highest standard of pure gold is only pure gold!

The difference between pure gold, pure gold and pure gold to buy ** jewelry, first of all, we must recognize the quality inspection mark of ** jewelry. The best jewelry sold on the market should be equipped with the inspection mark of the quality inspection agency, and the gold content and weight of the jewelry should be clearly marked with the logo. Pure gold:

The gold content is equal to or greater than the **, commonly known as the "10,000 pure gold series", and the mark is "10,000 pure gold" or "gold". Therefore, 10,000 pure gold is definitely 1,000 pure gold, but 1,000 pure gold is not necessarily 10,000 pure gold. There is a recipe for the identification of clear color gold in common cooked gold, which is:

Weigh the weight, look at the color, review the rhyme, fold the soft and hard, and use the acid point. Because the density is significantly greater than that of common metals such as copper, silver, lead, zinc, etc., it is about twice as heavy as silver and copper in the same volume. If the item is **, there is a heavy feeling, this is the "golden pendant" of the people's department, and vice versa.

What is Pure Gold? What is Pure Gold? What is Pure Gold?

We are also selling this, we have been selling for more than ten years, in fact, there is really no pure gold, the identification of the county appraisal can be identified with pure gold, only the provincial appraisal is more accurate, and the provincial appraisal is not up to standard. Many customers are stupid and say that there are thousands of feet, and we are also helpless! We sold it to him when we sold it to him, and he still stupidly believed that it would be good if the content could reach 1,000 pure gold.

To think like this, the bank we take the gold every time to the manufacturer to process, the manufacturer is equipped with spot solder, you say that you can reach 10,000 pure gold, some black manufacturers can not even reach 1,000 pure gold. . . Some stupid people think that they buy 10,000 pure gold, and some stupid people from Hong Kong go to Hong Kong to buy**The best to buy back** turned out to be 22k when 10,000 pure gold, running our store said that it was 10,000 pure gold, and also said**Hong Kong is cheap, **** In addition to gold bars, other finished products want to be cheap in the mainland, and insiders know. Some of Hong Kong's ** are also produced in the mainland, and some of our friends often receive orders from Hong Kong...

Unless the gold bar is worth it, see if it can be reached.

Ten thousand pure gold refers to the gold content of the first as raw materials, using the "solderless welding process" to process the jewelry, no electroplating and no solder, the overall quality is consistent, and the product color is all up to the top jewelry.

Pure gold is the highest value of jewelry in the market circulation. However, it is not included in the national standard, and the imprint is 10,000 pure gold, 9999 gold, AU9999 or G9999. **Jewelry imprints include manufacturer code, material, and purity, such as:

X Gold 990, X Au990, X Pure Gold, etc. Among them, the letter X is the manufacturer code.

The difference between 1000 pure gold and 10,000 pure gold is first of all in gold content. Ten thousand pure gold: the gold content is greater than or equal to, and the mark that appears on the ** jewelry and gold bar is "AU9999" or "Gold 9999".

Thousand pure gold: the gold content greater than or equal is called thousand pure gold, which is the most high-touch high value in the naming of jewelry fineness, and the imprint is "thousand pure gold", "999 gold", "g999".

The higher the purity of the **, the darker the color. The fineness of the thousand-pure gold is the best under the same circumstances, and the process required to obtain the fineness of the thousand-pure gold is more complicated if the gold content is to be guaranteed.

The softness and hardness of the texture, the higher the gold content, the softer the texture, which is also a means for the industry to identify the true and false.

In terms of the same weight, the pure gold of 10,000 gold is higher.

The so-called "gold is not enough", there is no content of 100% **, 10,000 pure gold can only be infinitely close to this value, everyone can choose their favorite products according to their own budget to decide whether to choose 1,000 pure gold or rent a tour of 10,000 pure gold!
