Speaking of "black people" and "poverty and backwardness" is not discrimination. Due to the historical problems left over from the African continent and frequent wars, Africa's economic development really cannot advance.
However, this part of Africa is rich in mineral resources, especially local jewelry resources. Then, because of Africa's own economic development problems, these jewels are sold very cheaply locally, but even so, not many people buy their gold and diamonds. Why?
First of all, straight women in science and engineering will tell you what diamonds are. What are the four factors that determine the value of diamonds?
In terms of chemical composition, diamond is the simplest of all gems, which is simply crystalline carbon. The crystal structure of diamond endows it with enviable characteristics, such as hardness, heat and pressure resistance, sparkle and fire color, which are incomparable in nature.
The quality and value of diamonds are usually determined by four factors, which are called "4C standards" and are usually as follows:
1. color, representing the color of the diamond itself or colorless;
2. Clarity, which represents the flaw degree of the diamond;
3. Cutting and punching represent the process quality;
4. catwig means that it has an influence on the size of diamonds. From a purely aesthetic point of view, the order of these elements should be:
1. Cutting and proportion; 2. color; 3. clarity; 4. Carat weight;
Because African diamonds are mostly the most primitive diamonds that have just been developed, they really look rough and feel rough and have no ornamental value. The most primitive rough diamond needs professional processing to present the beauty of diamond, but the processing cost of diamond is very high.
In fact, the road to buy a diamond and realize its value is still very tortuous. Sometimes, the price of the processed rough stone is higher than that of the finished diamond. Many people think it is better to buy the finished diamonds directly.
Therefore, China tourists with ancient civilization and wisdom will certainly not buy African diamonds!
