We call the coral jade fossil jade a coral jade. This jade word definitely refers to jade, that is, only the coral jade fossil of jade can be called coral jade. Therefore, Yuhua is very important for coral jade. Speaking of friends who may be here, may you ask if there is no jade in coral jade? Of course, and a lot, all jade and jade jewellery is a very important link, and the good value of jade can be doubled. If the jade is not good, it may be just an ordinary stone. An ore jade requires a very strict external environment, and this process has not been a unified statement to this day, but a little jade is very important. In the coral jade ore, a large part of the original stone is not jade, so its value is also very low, and even bluntly said that it is worthless. Only the hardness of the jade coral jade stone can reach the gem level. Only the coral reef jade stone of Yuhua can make the luster with pearly glory. There is a thick layer of skin on the outside of the coral jade stone. It is difficult to see the things inside under normal circumstances, so whether or not jade is completely judged by experience, I will talk about this with you here. This only represents me personally. Ideas.
Whether the coral jade stone is jade or not, the most important thing is to look at the weight. This is very important. It means that the jade is good, but the light hole is more, and what is the measure of this weight? This weight refers to the high density, that is to say, the density of jade is reached, then it will be very heavy. If it has laboratory equipment, it can be measured very quickly, but we often do not have the choice when choosing coral jade. What should I do with such conditions? By hand, we should be familiar with the words "pressing hands". The so-called pressing hand refers to the weight of a piece of coral jade stone. There is a number in the heart. When you pick up the weight of the hand, it is more important than the time of visual inspection. This coral jade stone is good, this is called Pressing the hand, but when you pick it up, it feels lighter than when you visually check it, then it means that the jade is not good or there is a big sand hole inside. This is the most effective way to judge whether the coral jade stone is jade.
Another point is that if you see the coral jade stone is relatively hard, generally the jade inside is better. If the skin is loose, the degree of jade inside should not be very good, but this is not absolute, depending on the actual situation. To judge. The coral jade stone produced in each coral jade mine area is not the same, so you should clearly distinguish the actual operation, so that you have the ability to select the coral jade stone.
