Gold is a very stable precious metal. From ancient times to now, gold is a symbol of wealth. Gold is also one of the rare and precious metals. Since gold jewelry was originally worn by rich and noble people, now the living standard has improved, and many people can afford to buy gold jewelry. At present, there are hard gold and thousand gold in the market. Although both hard gold and thousand gold are gold, the materials, processes and prices are different, so the quality is different. Let me distinguish the difference between them full gold is the purity of gold ≥ 99%. (in other words, gold or gold jewelry with a gold content of not less than 99% is called full gold.) Qianzujin is the purity of gold ≥ 99.9%. (that is to say, gold or gold jewelry with a gold content of not less than 99.9% is called full gold, which is the previous saying.) since May 4, 2016, the gold jewelry sold will no longer have the title of "thousands of gold", and all will be unified as "full gold", that is to say, there can be no terms of "thousands of gold" and "tens of thousands of gold". Now there are jewelry stores that publicize the purity of their gold, and then sell it at a high price. In fact, 99 gold jewelry and 999 gold jewelry are the same, and there is no difference in wearing them, and the recycling price is the same 3D hard gold is also called hard gold. It is the same kind of gold jewelry, but it is called differently. Hard gold is produced in the "electroforming" mode. It is formed by improving a series of factors such as gold content, organic brightener content, pH value, working temperature and stirring speed in the electroforming solution. The "3D hard gold" "Is the abbreviation of three -, which means three-dimensional graphics. That is to say, hard gold is hollow. Different processes are used in different positions of hard gold jewelry, some are frosted and some are polished, resulting in the contrast between the light and dark of the jewelry. It has a strong three-dimensional sense. When it is touched, some places are smooth and delicate, and some places have a slight frosting feeling, which makes it feel rich. the difference between thousand gold and hard gold: 1. From the purity, hard gold and thousand gold are both gold, and They are all full gold, and the amount of gold is the same. Therefore, some friends say that hard gold is an alloy, which is wrong. The words "hard gold" or "3D hard gold" are marked on the label 2. In terms of hardness, the difference between 3D hard gold and thousand gold jewelry is that the hardness is four times that of thousand gold. Therefore, hard gold has high wear resistance. Compared with thousand gold, hard gold jewelry has exquisite and light workmanship and is comfortable to wear 3. The difference between hard gold and thousand gold jewelry is that hard gold adopts hollow nano electroforming technology. So that the weight of hard gold jewelry of the same size is only 30% of the thousand gold. For example, the following thousand gold bracelet needs 20.29g, and it costs more than 7000 yuan if the gold price is 340 yuan. If it is made of hard gold, the maximum is 4G, which is about 1000 to 2000. Many people buy gold jewelry. 4. From the perspective of style, the difference between 3D hard gold and thousand gold jewelry is that hard gold uses wax model to reverse mold, So that gold can play a incisive role in space, and make art and jewelry better combined. Hard gold also adopts the advanced space dewaxing technology without solder joints and seams, which makes hard gold jewelry more vivid. Therefore, the styles of hard gold jewelry are diversified. The combination of hard gold and enamel makes hard gold jewelry colorful and makes hard gold jewelry more colorful and vivid.
The best gold is pure gold pure gold refers to 24 karat gold, which means its gold content is 100%. Theoretically, only 100% gold can be called 24 karat gold, but in reality, there can not be 100% gold. Therefore, China stipulates that only gold with a content of more than 99.6% (including 99.6%) can be called 24 karat gold Test Method: pure gold will not change when encountering dilute nitric acid, while the quality of gold and silver alloy will decrease when encountering dilute nitric acid, and the resulting liquid will be colorless, while brass will dissolve completely when encountering nitric acid, and the resulting liquid will be blue (due to Cu (NO3) 2), so dilute nitric acid can be used for test.
It depends on what occasion you use it. if it is an investment, it must be pure gold if it is worn daily as jewelry, the performance and style of K gold are more abundant however, no matter what it is used for, the pursuit of cost performance is the demand of most people if you are not a brand controller, it is recommended to purchase directly from the manufacturer our gold is directly purchased from Shangjin without intermediate links. Here you can buy the most cost-effective gold.
