To be honest, this thing can only be tested on the surface, and the words inside should be cut out for testing. There are more gold wholesalers there. Actually okay. Many people buy it there. There are no big brands outside. They bring the goods there. If you have high requirements, you can buy Liu Fu or Zhou Shengsheng and Zhou Dafu.
1. The gold content of not less than 999 is called thousands of gold, which is the highest value in jewelry quality. The logo is thousands of gold, 999 gold, GOLD999 or G999. The logo of gold jewelry includes manufacturers' code, materials, purity, etc., such as X Gold 990, XAU990, X Manjin, etc.
2. Among them, the letters X are the manufacturer code. When jewelry is made of different materials or different purity precious metals, the material and purity should be represented by the material and purity. When the jewelry cannot print because it is too thin or too small, it should be attached to the mark containing printed content.
The expansion information:
2015 The Spring Festival, the National Standardization Management Committee announced the first revision of the "GB11887-2012 Jewelry Jewelry Purification and Naming Regulations" and will be implemented from May 4, 2016. In the future, even the gold jewelry with a purity of 999.0 ‰ can only be marked as "full gold", and cannot be marked as "thousands of gold".
1. The jewelry logo should include the name and content of the manufacturer code and the precious metal material. It is mainly the test of specific process quality such as the overall shape and processing quality of jewelry.
2. The price of gold jewelry is calculated at weight and processing costs. The weight of jewelry is one of the important indicators. According to the standard, the metering unit of jewelry weight is grams, and the allowable deviation of single -piece gold jewelry is 0.01 grams.
3. The gold content of jewelry is an important indicator of its quality. There are many methods for testing gold, which can be divided into chemical analysis methods and instrument analysis methods. Depending on whether jewelry is damaged during the testing process, it can be divided into non -destructive testing and destructive testing. In the daily inspection of the jewelry quality supervision department, it is generally based on non -destructive testing method. The density method is analyzed by large -scale instruments such as X -ray fluorescent spectrum and electronic probe. Market supervision and random inspections are mainly concentrated in the detection of injury. Fire inspection is a national test method to determine the gold content of jewelry.
This thing is that the real detection can only be measured on the surface, and the inside should be cut to test. There are more gold wholesale over there. In fact, you can still pull it, and many people buy it there. The shops that are not big brands outside are all over there. If you ask for a high demand, you can buy Liufu, or Zhou Sheng Sheng Zhou Dafu.
