Jade identification skills

Jade, also known as jade jade, jade, jade, Burmese jade, is a kind of jade, the color is emerald green (called Cui) or red (called ç¿¡). It is a jade-like polycrystalline aggregate formed mainly of jade, omphacite and sodium chromite during the geological process. Today, Xiaobian introduces you to the jade identification skills.

Look at the ground: The meaning of the "land" of the jade is the degree of coordination between the green part of the jade and the cleanliness of the part other than the green and the water (transparency) and color, and the mutual relationship between "species", "water" and "color" Against the background. The folks call "land" "land" or "base barrier". Cui and Cui outside parts should be coordinated, such as Cuihao must be green and some outside the water, it is necessary to reflect the coordination, if the Cui is very good, but the water content of the outer part of the emerald is more dirty, called "good color difference." Cui's "water" and "species" should be coordinated, such as "species" old color is good, water is good, impurities are less dirty, set off against each other, strongly reflecting the emerald's love, light and value. The structure of "ground" should be delicate, the color tone should be uniform, the impurities are less dirty, and there is a certain degree of transparency. It is better to call "ground". Good "land" is called glass ground, sputum, egg white. Bad "ground" is called lime, shit and so on. The jade with bad water is called the "bottom dry."

Look at the water head: The "water" of the jade refers to its transparency, also known as the water head. The water of the emerald is related to the structure of the jadeite, that is to say to the "species". It is also related to the content of impurities. Those “ages” are old, have less impurities, have uniform particle size, and have high purity of jade water.

Look at the fog: The "fog" of the jade refers to a kind of semi-oxidized and slightly weathered jadeite between the jade skin (weathered or oxidized) and the interior of the jade (no weathering or oxidation) or meat. In essence, it is also part of the jade, a transitional zone from weathered crust to unweathered flesh (jade). The color and presence of the fog can indicate how much impurities are inside the jade. The "species" are always new, the transparency is good and the internal cleanliness. But it does not indicate whether there is green in it, not related to green. The fog is divided into white, yellow, red, gray, black, and the like. If the outer skin is worn away, it reveals a light white white mist, indicating that the impurities are less "ground" and have a certain degree of transparency. If there is green under the white mist, it is very pure green, and the value of the ground is matched with the ground. Liancheng. White fog also means that "the species" is old, and most people like to gamble on white fog. The yellow fog shows that the iron and other elements in it are gradually oxidizing, but there is no serious oxidation. If it is a pure yellowish fog, it shows that there are few impurity elements, and high cui often appears. However, sometimes the blue-green tone produced by iron ions may enter the jadeite lattice, and the greenish blue-green tone appears. The red fog indicates that the iron contained in it has been severely oxidized, and gray "ground" may appear inside the jade.

Look at the species: The “species” of jadeite refers to the structure and structure of jadeite. It is an important symbol of jade quality. The new "species" (also known as the new pit new plant, etc.) jade, loose texture, coarser grain size and uneven thickness, more impurity minerals, cracks and micro-cracks are more developed, but not necessarily poor transparency, specific gravity There is a drop. The old "species" (also known as the old pit old factory, etc.) jadeite, the structure is fine and compact, the particle size is fine and uniform, the micro-cracks are not developed, and its hardness has the highest specific gravity, which is the jade with good quality. But not necessarily transparency. The new and old species of jade is between the new species and the old jade. It is the jade that remains on the hillside and is not transported by nature or transported in a short distance. The new species of jade is the raw material for making jade B goods.
