Chinese people have always liked jade very much. Today, the most popular in China is jade and Hetian jade, both of which are widely favored by ordinary people. Although Hetian jade has a longer history than jade, jade is generally more popular, but in recent years jade prices It is gratifying that with the continuous improvement of national income, the emerald king who used to be in the upper reaches of the world has entered the homes of ordinary people today. More and more people love jade, appreciate jade, and collect jade. We should also have a better understanding of jade.

As the saying goes: "No grain is not a jade." That is to say, there are very few jade stones that are not found at all. Since jade contains almost all impurities, how do jade buyers identify the advantages and disadvantages of jade?

Green

Cui nature is actually a characteristic of jadeite. Strictly speaking, it cannot be said to be embarrassing. Because the crystals of jadeite are intertwined, there will be a flake-like flash under the illumination of strong light or natural light, which is what the insider calls "flying wings." The jadeite with thick structure of jade (such as bean) is more obvious, and the emerald of fine structure (such as glass) is less obvious.

Stone flower

Because the shape characteristics are different, the industry often refers to the density of the larger, the color is heavier, the seemingly dry and dry is called "stone brain" or "dead flower", the relatively scattered is called "starry", the density The smaller, lighter color is called “cotton” and the white and green is called “scallion with tofu”.

The obviousness of stone flower is often related to the "planting water" of jade. If the water is good, the stone flower will stand out, but when the water is poor, the stone flower is not obvious, or it is invisible. Some people may think that stone flower is the shortcoming of jade, but from another angle, stone flower can be regarded as a characteristic of natural jade.

Stone pattern

Stone pattern refers to the small gap between the jade crystals, which is not closely related to the jade crystal. It is the “stone pattern” understood by the jade industry. Because it is a small gap, many stone patterns are white or milky white, if there is a foreign color. The filling of the material will show a certain color.

If such small voids are arranged in a cluster or cloud, they become so-called "white cotton", "black cotton" or so-called "impurities". The stone pattern is easy to recognize under the transmission of transmitted light, but it is not obvious under the reflected light, or it only shows the change of transparency or the feeling of "green", which has less influence on the appearance of jade, and the firmness of jade. It depends on the size and number of small gaps.

Crack

The cleft of the jade is divided into two types: the primary cleft palate and the secondary cleft palate. The cleft of the jade, its "绺" and "crack" are to be explained separately, the split is called "crack", and the crack that heals or fills the material is called "绺".

The original cleft palate, the rock is produced by the geological movement; the secondary cleft is formed after the diagenesis is exposed to the surface. Some of the primary cleft palate has been repaired by late hydrothermal activity, or it is compressed by post-dynamic geological action, so most of the jadeite is filled with minerals formed later, especially debris. Late cleft palate, most of the naked eye can be clearly seen, the jargon is called "ribs."

Motley

Jade has a lot of color, and there are large and small colors. Small areas or dots of green, red, yellow, their presence can make the entire jade jewelry more beautiful and more characteristic, called the pretty color; small area or point-like black, brown, gray, etc., their existence can make the whole Jade jewelry is more ugly and lower-grade, called variegated; point-like black, brown, gray, etc. are also called dirty spots.
