Under the invisible guidance of Chinese traditional thoughts, the elders in the family like to buy gold, thinking that gold preserves value, and feels that even if it is not worn every day, it can be passed down for children in the future. Recently, it has been mentioned that there are decades of old gold in the family. 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’m worried that the future price of the old gold will grow very fiercely. After all, it’s an old thing decades ago, maybe worth it. inestimable. If the old gold and the new gold are put together, should ordinary people be able to distinguish them quickly? Let's not say how the texture is. At first glance, the old gold color is not as bright as the new gold. The surface is imprinted with traces of the years, and the new gold has a strong sense of luster. Apart from its own pattern, there is no historical sense of oldness. 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. 1. It is also a gold product. Why does old gold look yellower than new gold? 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. Moreover, in the old days, some gold shops used turmeric powder to add a layer of color to the processed gold jewellery, thereby increasing the color sensation of the gold jewellery. Therefore, the old gold looks yellower. The new gold is lighter in color because the modern polishing process is more advanced than in the past, so the new gold becomes shiny after being polished. The higher the brightness, the lighter the color. 2. It is also a gold product. Why does old gold feel softer than new gold? In the past, after the processing of old gold, there will be an additional process called “temperingâ€. The tempering is a kind of metal treatment process, which can reduce the hardness of the metal and enhance the toughness and ductility. Tempering gold jewelry can make jewelry soft. Nowadays, when processing gold, the process of tempering is cancelled. On the one hand, it is desirable to keep the hardness of gold jewelry to be worn, and on the other hand, it is not to weaken the gloss of the surface of the jewelry. Is the old gold worthless or worthless? Some people say that the purification technology in the past is far less developed than it is now, so the gold content is not pure, so the old gold is not comparable to the new gold. Some people say that the past adulteration technology is also much worse than the present. Therefore, the old gold in the past is the real gold of the right, and the older the more valuable. Let's take a look at it together. In fact, purely from the perspective of purity, the purity of old gold is not as high as the current gold. The regular gold jewelry sold on the market today can reach 99.99% higher purity. In the past, such technology was not achieved, and the purity was naturally It is not so high. The true value of old gold is not reflected in the purity of gold, but in its process value and historical value. Old gold, after the precipitation of time, can withstand the wind and frost of history, in order to have a place on the historical stage. If the old gold with a long history has more good craftsmanship, its value is much higher than its own material. How much do you know the purity of gold? Gold jewelry sold in the market, under the same conditions, the higher the purity of gold, the higher the price, so there are many words in the market such as “Thousands of Goldâ€, “Wanquan Gold†and “24k Goldâ€. However, some of the nouns have been banned now, here with everyone, how to look at the purity of gold. pure gold. In the past, there were such sayings as “Thousands of Gold†and “Millions of Goldâ€. Consumers always thought that the higher the better, the better. Now this kind of statement has been banned, and the unity is called "full gold." This is the traditional name of China's gold jewelry materials for the highest gold. Pure gold, due to technical reasons, can not extract 100% pure gold now, always contains some other metal impurities. However, as long as it can reach the full gold, the purity is very high. K gold. The quality of the jewelry made of pure gold is soft, it is easy to deform when worn for a long time, and it is difficult to put other jewelry on it. Therefore, in order to increase the hardness of the jewelry, people will add a small amount of metal (copper, silver, zinc, etc.) to the gold. Gold ornaments made of other metals are called K gold. The color of K gold is white, yellow, red, etc. The rose gold that is very popular among young people is actually K gold. However, the white K gold and platinum are completely different. In short, gold symbolizes authority and honor, and Chinese people have been very fond of it for thousands of years. Gold is full of traditional Chinese history, and is a collection of gifts and gifts. Gone with the world, Shengshi antiques, no matter in which era, gold has a very high collection and investment value!
