When Jade formation geological environment is very unstable at the time of the initial formation of the two jade, due to the geological environment changes, resulting in a squeeze between jade and reintegration, and the waterline is produced. Waterline is the same thing as the tendons inside a translucent jade, a linear or nearly linear form appears. This is called the waterline. Some people think that only the Qinghai jade waterline, and Tian is no waterline, in fact, is a big misunderstanding, Qinghai jade waterline distributed more messy, and more rules and nephrite waterline, the numbers are small, the small seed material can often be seen like a mountain stream line that is. And nephrite waterline in the end is how, extraction plant and nephrite Detailed join you. And nephrite a waterline, density. Waterline is inside a piece of jade denser areas, usually at the time of the master carver carving, if you encounter the waterline, will increase the difficulty of carving, in the processing of Qinghai material in general in order to avoid the waterline, will be along the waterline cutting. Second, how to observe. The vast majority of the waterline to the naked eye can see. Waterline to the naked eye is difficult to see a small part of the strong side light lamp can be found. This is why a business credit must provide photo translucent jade friends to one of the reasons. In particular, some hidden under the skin color of the waterline, naked harder to see, so, for professional players, small flashlight is one of the necessary tools. Third, the impact. If you are at the edge of the site in general, seed compound, waterline location, the case can be difficult to detect by the naked eye, and less impact on the value of jade. Fourth, the relationship between the waterline and sandeel. Sandeel waterline and should be regarded as a type of thing, the difference in the (in rubber bands, for example) is called the waterline stretched rubber band stretched, stretched rubber band did not have to fight or circling festival called sandeel. In short, the impact on the waterline and nephrite is not absolute, and some jade waterline, albeit obvious, but other aspects (such as density, oily, cleanliness) are better, but better to avoid or hide in the process of waterline, but more features, a very small impact on prices. If you use good waterline still is a good thing! Contact: Yujing Li Tel: 4006156603 Website: http: //www.yucunyuye.com Address: Nanyang City Tianguan Li River Logistics Park Avenue in the middle
