24K gold is only close to pure gold, and the proportion reaches 99.998%. The so -called pure gold does not exist. It has a little impurities. The following will introduce the category of imitation gold products and how to prevent. Ifging of golden products with a variety of jewelry, utensils, etc. with metals that are very similar to gold with gold, and have similar metals to gold. 1. The thin gold products are a kind of alloy made of copper raw materials made of bronze raw materials and mixed with rare earth and other elements. It is a new and high -quality imitation gold material for 80 years. The appearance can present a purity of 14-22K gold. Its wear resistance is better than gold, and has the advantages of quality light and hardness. Thin gold products are common in the inner ring with "CXXK", which means that this piece is equivalent to the purity of "XXK" gold, but it does not contain gold. 2, Yakin (tooth gold) Yijin refers to a alloy processed by copper and zinc as the main raw material, which is prepared by a certain proportion of smelting methods. The surface of the Asian gold products is golden yellow, which is often used in dental convergence and making jewelry. Compared with the real gold jewelry, Yajin has a certain sense of appearance in appearance. It is a common low -cost imitation gold material, but Yajin does not contain golden ingredients. 3, titanium titanium is a metal element, which has strong corrosion resistance. The chemical symbol is TI. If the surface of the metal products such as copper, aluminum, and iron is treated, the luster and color are very similar to gold. It is often referred to as titanium and does not contain gold. Narnever gold, Asian gold, titanium, and other accessories are characterized by beautiful shapes, clear purity, low price, and extremely golden. But light weight is easy to distinguish with gold products. If you use nitric acid points on these metal surfaces, plus salt, the metal is corroded. Manic value preservation effect of gold products and extensive use in the jewelry industry have always been used as an indispensable important content in the allocation of family assets. It has always been a topic of concern. I hope that the above will help you improve the ability of gold defense.
In strict sense, only gold with 100%gold content can be called pure gold, but in nature, there is no gold with 100%gold. Therefore, generally, we call 24K gold as pure gold. . The expression of gold purity: 1. "K gold" indicates the purity of gold The abbreviation of each opening (English cact, German Karat, often writing "K") gold content is about 4.166 %. 10k = 10*4.166%= 41.660%(417 ‰) 12k = 12*4.166%= 49.992%(500 ‰) 14k = 14*4.166%= 58.324%(583 ‰) 18k = 18*4.166%= 74.998%(750 ‰) 20k = 20*4.166%= 83.320%(833 ‰) 21k = 21*4.166%= 87.486%(875 ‰) 22k = 22*4.166%= 91.652%(916 ‰) 24k = 24*4.166%= 99.984%(999 ‰) 24k gold is considered a pure gold and became "1000 ‰", but the actual gold content is 99.99%, folded to 23.988k. 2. Use text to express the purity of gold The text marks on some gold jewelry, the regulations are: enough gold -gold content is not less than 990 ‰ thousands of gold —— The gold content is not less than 999 ‰ It, some are directly on the actual gold content. 3. Use scores to represent the purity of gold . If it is marked into 18/24, the color is 18K (750 ‰) If the marked to 22/24, the color is 22K (916 ‰) ) ) R n4. Use Arabic numerals to represent the purity of gold , such as 99 -indicate "foot gold" , such as 999 — indicating "Thousands of Gold" It is generally required that the production enterprise code, the name of the material, the mark of the content, etc. are generally required. The same is true internationally. But for some particularly small products, they are also allowed not to mark. . Testing method: people often use testing stones to determine the general content of gold. Testing gold stones are a mixed black mineral such as carbon -containing quartz and protein stones. Gold up is roughly color. Whether it is a natural gold or gold -made product, its color will change with the ingredients it contains. Pure gold: shiny dark yellow, thick yellow; silver gold: lighter color, slightly green; gold containing money greater than 25%: earth white; copper -containing gold: deeper color, red tone; silver containing silver; containing silver containing silver; Copper gold: yellow; gold containing zinc, copper, nickel: platinum. The golden color The higher the purity of the gold jewelry, the deeper the color. If there is no gold medal, you can determine the general color according to the following color (based on green gold. The so -called green gold contains only silver ingredients in gold); The pale yellow is 80 ~ 85%, the cyan is 65 ~ 70%, the color is only 50 ~ 60%white light, and the slightly yellow and white are less than 50%. It gold weight The proportion of gold is 19.32, which is more important than metal such as silver, copper, lead, zinc, aluminum. The volume of gold is more than 40%heavier than the silver, 1.2 times heavier than copper, and 6.1 times heavier than aluminum. The gold jewelry should have a feeling of sinking in the hand, 18K gold pendant, and fake gold jewelry feels light. This method is not suitable for gold jewelry inlaid. It gold hardness pure gold is soft and low. It can draw light marks with nails. Teeth bite can leave dental marks. Golden island, high -colored gold jewelry, low color, is low in color. The harder, the harder, the bending method can also test the hardness, the pure gold is soft, it is easy to bend, the lower the purity, the less likely to bend. Gold jewelry analysis: Gold jewelry refers to jewelry made of gold as the main raw material. The chemical symbol of gold is AU, the proportion is 19.32, and the hardness of Moh is 2.5.
24K gold can be said to be gold with very high purity, but not pure gold. Because there is basically no pure gold at present, the current thousands of gold, the amount of gold is not 99.9 % and 99.99 percent, the gold is very soft, and the pure gold cannot make the style. However, in theory, 24K gold refers to pure gold, which refers to gold with 100%gold content, but people are temporarily unable to refine gold with 100%gold content. gold. 999 gold is a thousand -footed gold with a gold content of no less than 99.9%, which is the highest value in the naming of jewelry. 24k what is gold? 24k gold is a gold product that is close to pure gold but not pure gold. 24K gold is considered to be pure gold, but the actual gold content is 99.998%. In theory, 100%gold can be called 24K gold, but in reality, it is impossible to have 100%gold. Therefore, China stipulates that the content reaches 99.96% The above (including 99.96%) gold can be called 24K gold. Also called thousands of gold. The understanding of 24K gold in society is thousands of gold. On the eve of the Spring Festival 2015, the National Standardization Management Committee announced the "Regulations on the Pureth of Puritatics and Naming" of GB11887-2012 "The Pigmentation of Jewelry Precious Metals and Naming Methods". It will be implemented on May 4, 2016. It can be marked as "foot gold", not called "thousands of gold", and there is no "24K gold" and "thousands of gold". 24k = 24*4.166%= 99.984%(999 ‰) 24K gold is considered pure gold, called "1000 ‰", but the actual gold content is 99.99%, and it is 23.988K. The purity (AU) 750 refers to the gold content range greater than 750.0 ‰ and less than 916.0 ‰. The minimum value within this range is 750 as the purity name. Gold with a content of more than 99.6%(including 99.6%) can be called 24K gold. Also called thousands of gold.
24K gold refers to 99.99%of pure gold, which is often called "foot gold" or "pure gold". The "K" of 24K gold is the writing of the word "karat". The complete statement: Karat Gold (that is, K gold). The characteristic of K gold jewelry is that the amount of gold is small, the cost is low, and it can be made into various colors. And improve hardness, not easy to deform and wear. K gold is divided into 24K gold, 22K gold, 18K gold, 9K gold, etc. It is understood that the method of using "K" to calculate the gold content is a kind of corner bean tree along the Mediterranean coast. The corner bean tree blooms a pale red flower, the nodular pod is about 15 cm long, and the bean kernel is brown, which can make glue. No matter where this kind of tree grows, the bean kernels they are concluded are exactly the same. Therefore, in ancient times, people used it as a standard for determining weight. Over time, it has become a heavy unit to measure precious and subtle items. In fact, as far as the level of science and technology is concerned, it is impossible to refine the pure gold material with a purity of 100%. Therefore, the golden position standard K in the gold content in the gold product generally refers to the pure gold as 24K gold, but it only contains 100%in theory, but it does not exist. Therefore, in the national standard, the gold content of the merchants that the gold jewelry must not use the irregular standards of "24K gold". Since the pure gold is 24K, that is, the theoretical gold content is 100%, then 1K means that gold products contain pure gold 1/24, about 4.16%. 18K gold represents the gold content of 18/24, which is 75%of pure gold, and the rest are other materials such as silver or copper.
First of all, let's talk about 24K pure gold. 24K gold is usually considered to be pure gold, but its actual gold content is only 99.99%. The pure gold here is not a single -quality element gold in the chemical sense, and there is no monocular gold with a purity of 100%in the world. At present, the only single quality that can be purified by 100%purity is to use a widely used single silicon in our electronic technology, which will not be introduced in detail here.
24k K is the purity of gold, and industry insiders also call it the saturation of golden colors. In fact, at the chemical level, K here means the English word "cact", which means the gold content. Internationally stipulates that each K represents 4.166%of the gold content. Obviously 24K means that the gold content is 99.984%, and it is generally considered to be 99.9%. Based on this type, 18K is also a gold code with the corresponding gold content.
It, we often hear codes such as thousands of feet gold and foot gold on the market. The thousands of gold here refer to gold with a gold content of 99.9%. Because the gold content is three 9, it is also called three 9 gold. Based on this type, the gold refers to the gold with a gold content of 99%. Because the gold content is two 9, it is called two 9 gold.
In short, we have to believe in one thing, gold is not red, even if the gold with a good purity is no matter how good the purity is, it is impossible to achieve 100 % purity.
24K gold is only close to pure gold, and the proportion reaches 99.998%. The so -called pure gold does not exist. It has a little impurities. The following will introduce the category of imitation gold products and how to prevent.
Ifging of golden products with a variety of jewelry, utensils, etc. with metals that are very similar to gold with gold, and have similar metals to gold.
1. The thin gold products are a kind of alloy made of copper raw materials made of bronze raw materials and mixed with rare earth and other elements. It is a new and high -quality imitation gold material for 80 years. The appearance can present a purity of 14-22K gold. Its wear resistance is better than gold, and has the advantages of quality light and hardness. Thin gold products are common in the inner ring with "CXXK", which means that this piece is equivalent to the purity of "XXK" gold, but it does not contain gold.
2, Yakin (tooth gold) Yijin refers to a alloy processed by copper and zinc as the main raw material, which is prepared by a certain proportion of smelting methods. The surface of the Asian gold products is golden yellow, which is often used in dental convergence and making jewelry. Compared with the real gold jewelry, Yajin has a certain sense of appearance in appearance. It is a common low -cost imitation gold material, but Yajin does not contain golden ingredients.
3, titanium titanium is a metal element, which has strong corrosion resistance. The chemical symbol is TI. If the surface of the metal products such as copper, aluminum, and iron is treated, the luster and color are very similar to gold. It is often referred to as titanium and does not contain gold. Narnever gold, Asian gold, titanium, and other accessories are characterized by beautiful shapes, clear purity, low price, and extremely golden. But light weight is easy to distinguish with gold products. If you use nitric acid points on these metal surfaces, plus salt, the metal is corroded.
Manic value preservation effect of gold products and extensive use in the jewelry industry have always been used as an indispensable important content in the allocation of family assets. It has always been a topic of concern. I hope that the above will help you improve the ability of gold defense.
In strict sense, only gold with 100%gold content can be called pure gold, but in nature, there is no gold with 100%gold. Therefore, generally, we call 24K gold as pure gold.
. The expression of gold purity:
1. "K gold" indicates the purity of gold
The abbreviation of each opening (English cact, German Karat, often writing "K") gold content is about 4.166 %.
10k = 10*4.166%= 41.660%(417 ‰)
12k = 12*4.166%= 49.992%(500 ‰)
14k = 14*4.166%= 58.324%(583 ‰)
18k = 18*4.166%= 74.998%(750 ‰)

22k = 22*4.166%= 91.652%(916 ‰)
24k = 24*4.166%= 99.984%(999 ‰)
24k gold is considered a pure gold and became "1000 ‰", but the actual gold content is 99.99%, folded to 23.988k.
2. Use text to express the purity of gold
The text marks on some gold jewelry, the regulations are:
enough gold -gold content is not less than 990 ‰
thousands of gold —— The gold content is not less than 999 ‰
It, some are directly on the actual gold content.
3. Use scores to represent the purity of gold
. If it is marked into 18/24, the color is 18K (750 ‰)
If the marked to 22/24, the color is 22K (916 ‰) ) ) R n4. Use Arabic numerals to represent the purity of gold
, such as 99 -indicate "foot gold"
, such as 999 — indicating "Thousands of Gold"
It is generally required that the production enterprise code, the name of the material, the mark of the content, etc. are generally required. The same is true internationally. But for some particularly small products, they are also allowed not to mark.
. Testing method:

The golden color
The higher the purity of the gold jewelry, the deeper the color. If there is no gold medal, you can determine the general color according to the following color (based on green gold. The so -called green gold contains only silver ingredients in gold); The pale yellow is 80 ~ 85%, the cyan is 65 ~ 70%, the color is only 50 ~ 60%white light, and the slightly yellow and white are less than 50%.
It gold weight
The proportion of gold is 19.32, which is more important than metal such as silver, copper, lead, zinc, aluminum. The volume of gold is more than 40%heavier than the silver, 1.2 times heavier than copper, and 6.1 times heavier than aluminum. The gold jewelry should have a feeling of sinking in the hand, 18K gold pendant, and fake gold jewelry feels light. This method is not suitable for gold jewelry inlaid.
It gold hardness
pure gold is soft and low. It can draw light marks with nails. Teeth bite can leave dental marks. Golden island, high -colored gold jewelry, low color, is low in color. The harder, the harder, the bending method can also test the hardness, the pure gold is soft, it is easy to bend, the lower the purity, the less likely to bend. Gold jewelry analysis: Gold jewelry refers to jewelry made of gold as the main raw material. The chemical symbol of gold is AU, the proportion is 19.32, and the hardness of Moh is 2.5.
