The elders in the family like to buy gold, because the gold value, even if not worn every day, can also be a heritage for the children. Recently, I have mentioned that I have been living in the family for decades. I don’t know whether to keep it or send it to the gold store to replace it with new gold. I want to change it. I feel that the old gold is too old, the style is not trendy, and I don’t usually wear it. I don’t want to change it. I am worried that the future price of the old gold will grow very fierce. After all, it’s an old thing decades ago, maybe worth it. inestimable. Why do Chinese people like gold so much? There are roughly three reasons for this - 1. The nature of gold is stable and it is difficult to change color. 2, the price of gold is relatively stable, although it will not rise, but it will not fall, compare value. 3. The color of gold is rich and rich, and it is a symbol of wealth. However, because the nature of gold itself is too stable, the gold that existed decades ago or even hundreds of years ago still exists well. This kind of gold is the old gold we are looking for. First, the new gold vs old gold, are you clear? If the old gold and the new gold are put together, should ordinary people be able to distinguish them quickly? In general, the old gold color is yellower and the texture is softer. The new gold color will be lighter and the texture will be harder. Because the old gold has been worn for many years, plus decades of or even hundreds of years of preservation, the surface naturally forms a layer of patina. In the old days, some gold shops used turmeric powder to add a layer of color to the processed gold jewelry, which increased the color of the gold jewelry. Therefore, the old gold looks yellower. 1. Old gold toughness, strong new gold, high hardness The hardness of gold is only 2~3, which is very soft, so it is often deformed by wearing it. Ancient goldsmiths often used the soil method of biting the teeth to identify the true and false of gold - because of the low hardness, the real gold bite can see the tooth print. If there is no tooth print, it means that it is mixed with impurities. However, they all say that it is a soil method and cannot be 100% believed. After the completion of the processing process, the old gold is called a “temperingâ€. Tempering is to reduce the hardness of gold, enhance the toughness and ductility, which is more conducive to the production of rich and varied gold jewelry in the past when the technological level is not developed. Modern jewelry processing technology is getting higher and higher, completely free from the constraints of toughness, but more inclined to increase the hardness of gold, which is conducive to wearing. Therefore, there is now a new technology called 3D Hard Gold, which is an emerging variety produced by a special process. Simply put, the ionic structure of gold is destroyed during the production process, making the hardness extremely high and not easily deformed. And damage, the hardness can reach 4 times of ordinary gold. 2, the old gold color is yellow, the new gold is strong In the past, in order to make the color of gold look better, the gold shop will use some turmeric powder to color the processed gold jewelry. Therefore, comparing the old gold with the new gold, the old gold will be more yellow. In the aesthetics of modern people, the glittering visual effect of the new gold is more deeply rooted than the yellow of the old gold. Therefore, after the new gold is processed, polishing becomes an indispensable process. In addition, after years of wearing the old gold, which has been yellowed, the surface will be oxidized to form a layer of patina, which is worse than the new gold. However, some people think that such old gold is as valuable as antiques. What do you think? Second, is gold the older and more valuable? In China, as long as a certain thing exceeds a certain "age", it becomes an antique. Even if it is not worth the money, it will become valuable after a hundred years. Will old gold be like this? Although old gold does not have the bright luster of new gold, it may not have such high purity, but its real value lies in its craft and history. After the precipitation and polishing of time, the old gold shows a different beauty in front of the world. The value given by this history is unmatched by the new gold. If the process of an old gold is very good, its value is much higher than its own material. If you are a person who pursues the old sense of history, then you are advised to collect old gold. If you are a person who loves new things, then you still buy new gold, rich in style and wide choice.
