In addition to the popular white jade color, Hetian jade has other rich colors, such as yellow, blue, flower, ink and other colors. These colors together constitute a rich variety of Hetian jade. However, there are still many people who will wonder why Hetian jade has different colors. Let's briefly explain it to everyone.
Everyone knows that Hetian jade is mainly composed of components such as tremolite and actinolite. The vast majority of white jade minerals are tremolite, and the green jade is mostly composed of erectite. The tremolite and the actinolite are in an excessive series. Due to the increase of iron, the tremolite will also become an actinolite. On the contrary, if the iron element in the radiant stone is reduced, it will gradually become a tremolite.
One of the most important characteristics of Hetian jade is the change of trace elements in it, which causes different colors, and the test has obvious laws. Such as; white jade, white jade, sapphire changes are calcium oxide, magnesium oxide, silicon dioxide is gradually reduced, and iron oxide is gradually increasing. Other chemical components also have certain rules. Although the changes are not large, they can cause the color of Hetian jade to be different.
For example, the chemical composition of Moyu is similar to that of Sapphire, but the carbon dioxide is as high as 1.43%, which is much higher than that of Hetian jade white jade. The presence of a large number of them can change the appearance of Hetian jade, such as the amount of cr, which is the root cause of Hetian Biyu. There is a close relationship between the amount of ti and the formation of ti.
