Jade collection first step: nephrite jade to distinguish
According to the theory of modern geology, jade is divided into two types: "hard jade" and "soft jade". "Jadeite" refers to jadeite, which belongs to the pyroxene class. It has a firm texture and a glass luster. The jade looks at the light and has a vague crystal structure. Its Mohs hardness is 7, the hardness is higher, the specific gravity is 3.33, and the jade has a heavy pressure in the hand. "Soft jade" belongs to the hornblende class, and its Mohs hardness is generally no more than 6-6.5, which is softer than jade. There are many kinds of jade in nephrite, such as jade, Nanyang jade, Lantian jade, Hetian jade, agate, crystal, coral, turquoise, lapis lazuli, etc., all of which belong to the category of nephrite. Later, due to the opening of the Silk Road, the jade produced in the Hetian area of ​​Xinjiang was unanimously recognized. It began to become the protagonist in the court, official and folk jade processing, and nephrite gradually became synonymous with Hetian jade. Hetian jade has already flowed into the Central Plains at an early age, but after the large amount of jade flows into the Central Plains or after the opening of the Silk Road, the jade is rich in color, the texture is warm, delicate and beautiful, and it is popular among people. The ancient people's life "Jade has five virtues", used to identify people, gentlemen have no reason, jade does not go to the body, forming a unique jade culture in ancient China. Hetian jade has a hardness of 6-6.5 and a specific gravity of 2.963.17. Due to the different composition of Hetian jade, Hetian jade is divided into white jade, sapphire, jasper, ink jade and topaz in color. Among them, topaz is the rarest and rare, followed by Sheep fat white jade (named for its warm and white as sheep fat), the number of ink jade is also very small. Sapphire is the most abundant jade in Hetian jade, and it is also the jade with the lowest quality and price. In the Xia, Shang and Zhou Dynasties, China has had a jade processing industry. So far, it has been stretching for thousands of years. Due to the limited minerals in Hetian jade, it has rarely been produced. Therefore, there are currently unscrupulous merchants in the jade market. White jade and Russian white jade pretending to be jade articles of Hetian jade, profiteering.
