Natural jadeite is only polished and polished, without any chemical treatment, without artificial artificiality such as high heat and high pressure. It is a natural color, without dyeing or electric color, and is called "positive color" or "true color". The texture of the naked eye is fine, the color is soft, and the handcuffs have a heavy feeling, which is obviously different from other stone. Since jadeite is natural, there will naturally be some natural cockroaches. The existence of these cockroaches does not affect people's evaluation of this jadeite as a natural A cargo. So is the jade with a little black spot still a natural A cargo? The answer is yes.

Sometimes it is a single short black filament, and sometimes it is a wide or narrow filament sheet. Sometimes they are densely packed together, from a small range, they are black silk, and in a wide range, they are veins. However, the black silk does not appear completely alone, but is often twisted together with the green silk. The boundary between the two can be distinct or unclear, the color depth is black, and the color is light green. 3, black spots Black spots refer to the spotted black objects that exist in the green of jade. They have a variety of shapes and sizes, and are often distributed in jadeite that is rich in green and watery. The kind of black spots that exist alone, or the distance between the black points, is generally called a "black dot." The slightly larger black spots are called "fly cockroaches", those with flash characteristics are called "black stars", those with wraps are called "sand nails", and those that are shaped like a small sand hole after grinding are called "sand packs". 4, other The white spots in the transparent jadeite that are good in kind (green, uniform, dense, delicate and tough) are called "white nails". When black spots or white nails are grouped together, they are called "intensive". Scorpion." There is also a dark dot called "green dot." Craftsman believes that "the jadeite material with black spots is old." Here, the "old seed", in addition to the delicate and delicate texture, "water head", the most important thing is green and rich. In other words, the old green jade material is prone to black spots.
