Dividing Hetian jade by color has long been a common practice. In June 2012, the new version of the Hetian jade local standard issued by the Xinjiang Uygur Autonomous Region Quality and Technical Supervision Bureau began to be implemented. In the new standard, Hetian jade was officially divided into eight varieties namely Yangzhibaiyu, Baiyu, Qingbaiyu, Sapphire, Topaz, Sugar Jade, Jasper, and Moyu.
However, the color you see with your naked eyes is really the kind that you have in your heart? That may not be the case.
Immediately, what we are going to see is three different types of "black" and Tian Yu.
When it comes to black Hetian jade, most jade friends may think of "moyu" in the first time. Therefore, this first piece of work, we will first look at the ink jade. Many friends may not know that the jade in Hetian jade is actually formed by the intrusion of white jade or white jade by graphite.
Moyu-Niu brand
This jade brand is full of dignity, above the jade, high relief and a lively cow head. The whole craftsmanship is unique, and it is like a cloud shape. Under the bull's head, there is also a wishful cloud pattern. In the jade carving, the cow has the meaning of turning around and smashing the sky. The jade is delicate and oily, without cracks.
The second one, let's look at a piece of black sapphire material. Black sapphire is a special variety in sapphire, which deserves special attention from collectors, especially the black saplings. This kind of material is almost black under normal light, and it can only show blue-green under strong light. This kind of sapphire material generally has a fine internal structure and a texture, which is called the best in black sapphire.
(black) sapphire material pendant - Buddha cited Fulai
This work is made from a selection of sapphire seeds. The jade is fine and greasy, and the color is black and dark. Maitreya leans on the rock, smiles and looks at the details. The appearance is sturdy, the clothes are smooth and natural, and the bats in the upper left corner fly. Buddha attracts Fulai, peace and tranquility, and wealth. There is no grain on the back, leaving a piece of skin, and the pores on the skin are clearly visible.
In addition to the jade and black sapphire, there are black jasper in the jasper.
Black Jasper - Shuanglongpei
This pair of jade jade is dense and moist, and it is excellent in oily and bright. The front side is a pair of dragons, the dragon body is bent, the claws are flying, and it seems to take the clouds straight up to the nine. The work is finely crafted, full of charm, and the combination of relief and enamel carving makes the whole piece look full of layers.
I have seen these three kinds of "black" and Tian Yu. Are you very stupid and unclear, so that you have the urge to scratch your head? In fact, it is not necessary, because the omnipotent jade friends have already found the simplest way to distinguish, that is, strong light.
The ink jade seed material has a light transmission pattern, and the halo is white.

Ink jade light transmission map. It can be seen from the figure that there are some black spots in the green halo.
Here, one thing we want to emphasize is that the above three pictures are all illuminating, so don't take any flashlight and complain that the light transmittance is low. In addition, the yellow-green halo and the green-green halo are not similar, and these require special attention and careful identification.
Finally, Hetian Moyu is caused by graphite immersed in white jade. Although there is usually a white halo when it is hit with a strong light, the halo is usually small, about 2 mm, so it cannot be light. It is very real. Yue Yunhui, the deputy director of the Xinjiang Rock and Minerals Gem and Jade Inspection and Research Center, also said that Hetian Moyu also has opacity. This opaque ink jade is delicate and very oily. It is difficult for novices to identify. Therefore, what we have said above is only some of the simplest and most popular identification knowledge. If you are not sure, it is better to send it early.
