How to distinguish the quality of Hetian jade: several common defects of Hetian jade

In the process of formation, Hetian jade has been subjected to high-strength impact, squeezing, expansion and fracture by various external factors for a long time, especially the external force of the seed material falling from the mountain into the river channel is more violent, and the probability of forming a crack is greater. Big. Therefore, there will be ten seeds and nine cracks in the process of forming Hetian jade, which has been subjected to high-strength impact, squeezing, expansion and fracture by various external factors for a long time, especially the external force of the seed material falling from the mountain into the river. To be violent, there is a greater chance of forming a crack. Therefore, there is a saying of 'ten seeds and nine cracks'.　　　　 The flaws of Hetian jade are inevitable, but some flaws are innocuous, and some are fatal.　　　　1: Waterline 　　　　 Waterline is one of the most common defects of Hetian jade, which greatly affects the appearance, and many people are more concerned about this. However, in terms of texture, the waterlined material is more delicate than ordinary materials. 2: stiff stiff refers to the relatively heavy and nephrite Agariishi part, feel a glance jade and stone are not separated. There is a saying that good meat comes out of a stiff edge, which means that the jade around the stiff is usually more delicate and oily.　　　　 There are two kinds of stiffness, one is stiffness, and the other is stiffness. If 　　　　 is stiff, there is a lot of room for the jade carver to play. As a skillful carving, it may also be an alternative beauty.　　　　 But if it’s stalemate, then I don’t recommend you to buy it. The impact of channel stiffness on the jade as a whole is very large, even if the carving is added in the later stage, it is difficult to make a better finished product.　　　　3: 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 the cracks all the cracks on the cracks of the cracks on the cracks, the small cracks, about three or four millimeters, the size of rice. Cracks are slightly larger cracks. Together they are called'crack'. Some of the reasons for the formation of 'crack' are caused by external factors in the process of forming jade, and some are caused by the process of mining and transportation.　　　　 Regarding the “acquired” cracks, whether it is processing or transportation collision, once formed, it will affect the tightness of the jade, and then will gradually expand over time, or cause the bracelet to break.　　　　4: Cotton 　　　　 Cotton is an aggregate of white crystals in Hetian jade, and its ingredient is silica. In Hetian jade, whether it is seed material or mountain material, there is cotton wool. No matter how good the lubrication is, no matter how delicate the material is, this phenomenon will occur, but some can be seen with the naked eye, and some are hidden in the jade.　　　　5: Dirty 　　　　 　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　.　　　　 dirty is the most unwelcome kind of flaw. For jade gambling people, dirty is the most fatal flaw.　　The material that looks good on the surface　　is dirty inside after being cut.　　　　Dirty is easy to run around, causing the whole material to be covered. Although this material like dragon fruit can also be made into a finished product, but for people with intensive phobia, it is really worth seeing goose bumps.　　　　 For the original Hetian jade, flaws are inevitable. When choosing Hetian jade, it is best to choose some smaller flaws.　　The above is the author's summary for you on how to identify Hetian jade. The information comes from the Internet.
