What is the Korean material in Hetian Yuzhong?

Korean material refers to jade produced in South Korea. It is a kind of nephrite. In a broad sense, it is also Hetian jade. Its mineral composition is similar to Hetian jade, with only minor differences. According to China's gem naming standard, it can also issue the identification certificate of Hetian jade. However, the value of Korean materials is far less than that of Hetian jade. Therefore, when purchasing, friends must carefully identify the difference between jade and Korean materials produced in Hetian.
The main source of Korean material is Chuncheon in South Korea, which is associated with serpentine and is yellowish or brown in color. All of the Korean ingredients are mountain materials, and no seed material has been found for the time being. The chemical composition of Korean materials is mainly tremolite, which is very different from Hetian jade. It differs only in some trace components, but the hardness and gloss of Korean materials are not as good as Hetian jade. Small differences are difficult for people to recognize, and the appreciation of people who play jade is very demanding.
In terms of various factors, Korean material is only a medium- and low-grade jade material. The jade material with better quality is white in color, shiny in oil and fine in texture. It is still acceptable as an ornamental jade, but it is collected. The value will not be too high. As for the poor quality of Korean materials, the value will be lower.
South Korea and new jade materials, North Korea has historically tribute jade to China, and the currently mined Korean material is a newly discovered pit. If a jade material looks better, the waxy luster is stronger, the structure is slightly looser, the hardness and density are slightly lower, and the price is lower, most of them are Korean.
Although the value of Korean materials is not too high, and there is basically no potential for appreciation, it is quite good as an ordinary decorative utensil.
Through the brief introduction of the above series, I believe that friends now have a new understanding and understanding of what Korean materials are. If you want to know the relevant knowledge, you can go to China Jewelry Merchants Network for detailed inspection!
