There are dozens of types of jade: old pits, white-green, blue-and-white, oil-green, bean, and hibiscus. The most high-grade ones can be regarded as old glass. "Water head" is the word of the family, referring to the transparency of the jade (ie "species"). If the transparency is high, the connoisseurs call it "the head of the water"; in turn, the one with low transparency is called "the head is short." The higher the transparency, the better the jade quality and the higher the price. We must be careful when observing the emerald water head, because transparency is related to the thickness of the jade itself. Be especially careful about the hollowing out of the jadeite products, because the hollowed out part of the jade is thinner, the light is good, and it looks like the water head is long.
Insiders divide the jade into A goods, B goods, and C goods. A goods are original jade without artificial heat such as high heat, high pressure (not "B" or "electric color"), the original germplasm is already like this, the color is natural, commonly known as "positive color" or "true" color". A goods are not necessarily the first-class high-end goods, but they are not "evil colors". They do not remove impurities and glue the upper board, and have not burned them. A goods themselves are also divided into many levels.
B goods are not light secondary jade or defective products, but will be handled manually. For example, the impurities in jadeite are dissolved by strong acid, which destroys the molecular structure of jade; The B j, which is usually heated by a high-temperature electronic jar to remove the turbidity, will make people suddenly feel that the head is long; in fact, the jade is not natural, nor fine; although it can make people feel illusory and transparent. In fact, the structure has been destroyed, because the high heat, the jade has been loose. Therefore, we should not buy austerity and blindly believe in people. Many folk B goods pretend to be A goods, which is basically a substandard goods. The artificially processed "bottom goods" B jade will gradually lose its luster and crack, because it has been burned by high heat, so it will be like oil after a few days. The germplasm, moisture and green color of A cargo jade are permanent.
C goods are as bad as B goods. They are dyed goods, commonly known as "electric color" or "color". After repeated heating and dyeing procedures for more than ten times, they will be discolored in case of high heat in the future.
