**Generally speaking, it can be divided into four types, of which pure gold is generally the most expensive because of its high purity.
1. Red gold. It is close to the meaning of pure gold, but due to the difference of time and place, the standard of red gold is different.
It is called red gold. And the red gold in the territory is generally in between.
2. Color gold, also known as "secondary gold" and "tide gold", refers to gold with low fineness. Due to the different content of other metals, these ** have a high fineness of up to 99% and a low color of only 30%.
According to the different divisions of other metals, cooked gold can be divided into clear gold, mixed gold, K gold, etc. Clear color gold refers to ** only mixed with ** ingredients, regardless of the color of the general term "clear color gold". Clear gold is more abundant and is commonly found in gold bars.
Gold ingots, nuggets, and various utensils and ornaments.
3. Mixed color gold refers to the fact that it contains copper, zinc, lead, iron and other metals in addition to the metal. According to the different types and quantities of metals contained, it can be divided into small mixed gold, large mixed gold, bronze large mixed gold, leaded large mixed gold, etc.
4. K gold refers to silver and copper in a certain proportion according to pure gold.
** formulated for a formula of 24k. Generally speaking, the greater the proportion of K gold in silver, the greener the color; If the proportion of copper is large, the color is purple red.
k-value. The percentage indicated.
It's just an approximate number, and it doesn't need to be very accurate. It is customary to use even K values, such as 24k, 22k, 20k, 18k, etc. The meaning of 18k means that 18 parts of gold are contained in 24 parts of alloy, which is equivalent to about 75% content. K gold.
Calculation method: You say that the formula for calculating the gold content of k gold is: k value 24 100% (i.e. k value

centimeters of bricks are dominant. The third category refers to alloy gold bars.
For newbies, which one is more valuable, gold bars and gold bricks? Let's give you a brief analysis. Judging from the news of this year's China ** Association, the BRICS framework will be accelerated. It may be the 14 BRICS countries that will be realized by the end of this year.
As the closest BRICS country, the BRICS integration strategy represents the overall strategy of national development, that is, the integration of politics, economy, culture, environmental security and social management. Building integration in the political, economic, cultural and environmental security of our country.
As a reminder, there is also the Republic of Panama of the United States. Panama is a federal protectorate directly under the United States, the United States manages Panamanian finance, the United States recognizes and protects Panama's sovereignty, and the United States can formulate and foreign products and other related rights and interests.
This is actually not a good thing for the ** market, at least for those who need money. **The market has just entered the integration of politics, economy and finance, in fact, the pressure on the domestic market has already begun.
And there is one place that can give us a little inspiration, that is, the ** origin. It is said that the more origins, the better, and the better the value retention. In fact, this is not entirely derogatory, which shows that our country's investment can not be integrated, because any country's ** reserves, basically will contain a lot of different origins of different metals, if only a single metal is invested, it will make the reserves dispersed, the total amount of reserves will not change much.
If you don't pay attention, only invest in the origin, you may encounter the situation of spending hundreds of thousands of dollars but only investing one or two hundred tons**. It turned out that it was possible to invest in copper like this, but later the first to adopt strict inspection and control of the origin, in fact, there were only more than 100 tons of copper left in the market, and there was not much more to use to make bulk consumer goods.
In terms of promoting integration, there is another aspect that the country needs to pay attention to, that is, alloy gold bars and gold bricks.
In fact, many people don't know that copper and lead are alloy gold bars issued by a country, and this alloy gold bar is the most valuable in the world.
Therefore, in addition to looking at the origin, we should pay attention to the alloy gold bars.

**Divided into red gold, color gold, mixed gold, K gold, red gold for the gold content of the above**, this ** because the color is red yellow and named. Colored gold is 30% of the gold content of 99%, mixed gold is contained in the metal in addition to copper, zinc, lead, iron and other metals, K gold is the alloy of smelting with other metals.

For many people who want to buy jewelry, they are very confused about which one to choose, and they don't know how to choose, and they are also confused about 18k** and **, because ** are not cheap, and they are afraid of buying it back and suffering a loss. Here, I will briefly talk to you about the difference between 18k**and**.
18k** yellow.
18k** and ** distinction.
Internationally, it is divided into 24k, and the content of each k is there, because there is no 100% pure gold, and the highest content is. And the **content of 18k** is only 75%, so if you just look at the **content**, it will indeed be more expensive.
18k** and **** comparison.
Purity. From the point of view of **content, 18k**** is lower than ****, unless there is crushing in the number of grams, otherwise **** is more expensive than 18k**.
18k** yellow.
Gemstone fee. Because of the physical properties, the higher the purity, the softer and easier it is to pinch and deform, so it is impossible to set gems in the current **jewelry, because it is very easy to fall off the diamond. And 18k**Because of the use of the exclusive research and development of K yellow patch, the hardness is more than 4 times that of **, so it is very suitable for inlaid gemstones, and the 18k** inlaid with gemstones is immediately **a lot, so the 18k** inlaid with gems is more expensive than **.
Which is better to buy 18k** or **?
If you are asking which one is better to buy, and you think it will be better to buy 18k**, it is recommended from these perspectives. First: high hardness, because of the high hardness of 18k**, it is more suitable to wear out, because it will not be deformed at will.
In addition, because of its high hardness, it can be made into a variety of shapes and inlaid with gemstones, making the styles more beautiful and diverse. Second: anti-wear, 18k** adopts the leading international electroplating process, so the surface of the jewelry has better anti-wear ability, and there will be no scratches when it is easy to rub, but it is very likely that a little friction will cause scratches.
The above two points are the recommended points of 18k**, and it depends on your own choice.

The common ** on the market is divided into two categories: pure gold and alloy.
Pure gold, that is, the so-called thousand pure gold and ten thousand pure gold, gold content, it is common in the market name pure gold 999, pure gold 9999, **, 24k gold.
K gold is an alloy, and the K value is 1-24, theoretically speaking, every K value can be deployed, but it is not necessary to consider the cost. The common karat gold in the market is 9k, 14k, and 18k.
**The main factor in pricing is the gold content, so the lower the k-value, the cheaper.

Summary. **Mainly divided into 24K, 22K, 18K, 14K and so on, of which 24K has the highest specific purity, but its hardness is low and should not be used for a long time; The ** specific purity of 22K is slightly lower than that of 24K, and the hardness will also be higher; 18k and 14k are the most commonly used ** jewelry, which is less pure than but has a higher hardness, making it suitable as jewelry.
