The difference between Moyu and Black Bi

In the traditional sense, the jade is specifically formed by the intrusion of white jade and sapphire by graphite. As the jade, of course, the darker the better, but it must have jade, otherwise it is stone, most of the jade is gray and gray. It is not black or white. This material is called "blue and white". Generally speaking, the jade quality of "blue and white" is quite delicate, and the fat is very good. It has a unique feeling. The black and white "blue and white" is very popular among jade. Can be used for clever carving, black and white distinct blue and white seed material commonly known as black and white, top grade requirements "white as rice paper, black as ink", the market is easy to be confused with Hetian "blue and white" is the unique Qinghai jade, in general The color transition of Qinghai Yanqing jade is natural, there is no scatter characteristic (no ink dots can be seen), because its black color is not caused by graphite infiltration.

The correct division of traditional ink jade is divided into point ink, ink collection and full ink according to the shape of graphite. As the name suggests, graphite is dotted in a point; graphite is denser in graphite, but it does not fill the original jade, the appearance is black and gray; the whole ink is graphite, and each space of the original jade is occupied. And very dense, the whole black "black as pure paint" is the top grade, very rare!

Black Bi is a common jade species in Xinjiang. The color is darker than the point ink and the ink, so it is also called ink jade, but the essence is jasper. Because of the black color on the top, it is very easy to confuse the whole ink in the traditional jade, and the whole ink of the jade bottom is easily mistaken as black. I personally think that the main point of the difference is that it is punched in with glare. The jade at the bottom of the sapphire can see even and fine ink spots, while the black bismuth can be seen like the algae of the seaweed. The traditional jade is in the strong light and close to the jade. When entering, a jade layer of transparent film plastic is visible between the light layer and the ink layer. As far as the hand is concerned, the full ink of the sapphire bottom is soft, and the toughness is good, while the black bismuth is hard and crisp, and the appearance is bright.

There is also a black serpentine in Xinjiang that is often filled with black and blue. The locals call it "Kava Stone". The Wei people mean "the stone without jade". These snakes are produced in almost all mines producing Hetian jade. Stone. The difference lies mainly in hardness and jade, but even if it is black, if it is not jade or stone, it is also a stone.
