South Red Agate has become a "black horse" in the wenwan collection in recent years due to its oily texture, attractive color, and rare mineral reserves. It is precisely because Nanhong is loved by everyone, some unscrupulous merchants use “junk goods†to deceive consumers, so as to make huge profits.
1, more impurities cracks
South red material is very brittle. When it is processed into jewelry or carved pieces, it is very easy to collapse, and it is necessary to cut the cracked part of Nanhong. It can be said that the loss is very large! The original red crack of Nanhong is still more Can be cut off, but if the finished product is also too many cracks, it will affect the beauty and texture of Nanhong, and such South Red also means no collection value!
2, the raw materials can not buy
The quality of Nanhong raw materials is very important. Only raw materials can make a foundation for becoming a boutique. Buying a hundred pieces of general goods, it is better to buy a boutique. There is no value in general goods, and the boutique is not only beautiful, but also has a certain appreciation space, which is a good choice for investment collection. Good South Red raw materials, to meet the color, texture and other factors.
3, the carving is poor, the shape is wonderful
Good work with good materials, if the raw materials are good, but the carving process is not good, then the final finished product will not have much value. If the raw materials are good and the engraving process is good, it will undoubtedly add a finishing touch to the collection and enhance the collection value and appreciation potential of the whole Nanhong works. In particular, Nanhong, which was carved by a famous artist, has been turned over several times. This shows the importance of the carving work to the value of Nanhong.
4, injection of plastic red
The injection of Nanhong is to inject the cracked Nanhong with glue, and then seal the wax to achieve the sub-filling effect. If you are buying Nanhong, you will be careful if you encounter Nanhong, which has no traces and no cracks, but the price is very cheap. 70% are glued!
1 Use a purple light to illuminate the south red. If the fluorescence reaction is found, it is proved to be a plastic red.
2 Under normal circumstances, the surface of the glued Nanhong is very uneven, as long as it is boiled in boiling water, it will immediately appear. But this method is not recommended for everyone to use, because if it is really natural and good, it is a pity to cook it!
5, dyed south red
Dyeing is simply the all-in-one of all gemstones. It is also the most abominable method of falsification. Dyeing is the process of adding Nanhong to a chemical agent and then achieving discoloration in a high temperature environment. Its chemicals can cause great damage to the body.
1 The color of dyed South Red is more unnatural than the burnt color of South Red, and it feels floating on the surface, while the natural South Red will bring a sense of grease.
2 Stained South Red gaps and perforated areas usually have different shades and larger porosity.
