Species refers to the essence of the texture of jade.
Jade is the essence of heaven and earth, and jade is the king of jade. This explanation is a bit like a prince, some are born in poverty, some are born noble, have a slap, and have a twin. The spiritual thing of jade is made up of small, very young seeds that have been slowly grown by thousands of years of Jing Yuehua. Each seed has a different characteristic. The noble jade seeds absorb the essence of the earth and become a crystal-clear old jade; ordinary seeds grow through the same time, and because of their poor variety, they can only produce jade like stone.
Therefore, "species" refers to the variety of jade texture, and is a comprehensive evaluation of the quality of jade. It contains the structure of the jade, the thickness of the emerald jade, and whether the jade crystal is transparent.
Whether the jade structure is close or not is the most important criterion for judging the goodness and difference of jadeite species.
Jadeite is formed by the primary ore of jadeite, which is metabolized in the special geographical environment of long-term low temperature and high pressure. The more complete the explanation is, the closer the jade's fiber interweaving structure is, the harder the jade is, the better the species, we call it old. On the contrary, in the formation process of jadeite, the more incomplete the confession, the interwoven structure of jadeite fiber is not formed sufficiently, and the relatively loose structure is called “species difference†and “species tendernessâ€. The jade with tight structure is more difficult to cut than the jade in the processing. In addition, the jade with tight structure can see that the surface has a good luster. Even if the jade is thicker, the transparency is not very good. This is a good surface gloss. This is why it is old and tightly structured.
Judging whether the "seed" new and old second standard is whether the jade meat is delicate. Under the same structural tightness, the finer the jade meat, the better the texture it shows, and we think it is better. Some old jade, jade meat thick, we can clearly see its phenocrystalline structure with the naked eye, some jade meat is delicate, the eye can not see the jade porphyry, but if it is not enough, under the ten times magnifying glass It is still very clear to see the jadeite phenocrysts, which can be seen with the naked eye to see many tiny undulations on the surface. If the jade meat is very delicate, it is very difficult to find the above phenomenon. Only the jadeite, the ice species, the golden silk species, and the glass species can be seen. However, if the jade meat is too delicate and over-the-top, there will be an opaque phenomenon of jade, without the characteristics of jade.
Whether the emerald is new and old, and whether jade has good transparency is an important factor in judgment. In the case of a certain structural tightness, the more transparent the jade, the older its species, the older we think it is, the more valuable it is. Decide whether or not the jade has a great transparency. Whether the crystal itself in the jade is transparent or not is the determining factor. If the jade meat contains a lot of opaque minerals, the emerald transparency is poor. The uniformity of jade meat in jadeite is also a factor affecting the transparency of jadeite. In the formation of jade, the closer the fiber interweave structure, the better the transparency.
The main categories of "species":
First, according to the size of the mineral crystal particles inside the jadeite, can be divided into: glass, ice, alfalfa, hibiscus, horse teeth and bean species.
1. Glass type: The transparency of jadeite is as transparent as glass. The internal crystal structure of jadeite is micro-microscopic structure. Crystal particles are not visible under the naked eye. The particle size of the constituent mineral crystal grains is less than 0.07 mm.
2, ice species: jade transparent to translucent, slightly less transparent than glass jade, the internal crystal structure of ice jade is also micro-microscopic structure, can not see the crystal particles under the naked eye, the crystal size of the jade interior is slightly larger than the glass species Jadeite, composed of mineral crystal particles with a particle size of 0.07-0.1 mm;
3, cockroaches: the head is lower than the ice species, it is translucent, observe the jadeite under the light, giving the impression that it is as turbid as the soup cooked by glutinous rice.
4, hibiscus species: the color of jade is generally a faint green, green is more pure green, the body color is uniform, the texture is thinner than the bean, the structure is slightly grainy, but can not see the particles, transparent to half Transparent, it looks like a clear feeling of water and hibiscus.
5, horse teeth: jade texture is rough, poor water head, jade on the common yellow, rice-like small points, looks a bit like porcelain, but also a bit like a horse's teeth.
6. Bean species: The crystal grains are rough, and the crystal particles of jadeite can be seen under the naked eye. The water head difference of the bean seeds is slightly dim to translucent, and the particle size of the constituent mineral crystal grains is larger than 0.1 mm.
Second, according to the density, hardness and inter-crystal combination of mineral crystals in jadeite, it can be divided into: old species, new species and new and old species.
1, the old species of jade: also known as the old pit species of jade, refers to the combination of crystals inside the jade, the combination of mineral crystals, the density of a class of jade, the characteristics of the old jade is: jade interior crystals and crystals The cementation is tight, the density is high, the crystals are well combined, the hardness of the jadeite is high, and the appearance is that the surface of the jade is particularly strong, and the gloss is fresh and translucent. The cause of the old jade is that after the diagenesis of the jade stone, after the late dynamic geological action, the internal crystal structure of the old jadeite is relatively dense. The old jade is mainly produced in the riverbed sand ore mining area.
2, the new species of jade: also known as "new pit species jade", refers to jade diagenesis after no or only experienced weaker late stage dynamic geological transformation of jade, new species of jade, its internal crystal and crystal between the relative old jade In terms of crystal cementation, the density is poor, the crystals are not well bonded, and the structure is loose. Therefore, the new jadeite is inferior in hardness and surface glossiness than the old jadeite.
3, the new and old species of jade, is a kind of jade between the old jade and the new species of jade. New and old species of jade are common in the step sand deposit.
Third, the graphic display:
1. Old pit glass type: the highest level of transparency, the head of the water is the most abundant, the Ying is transparent, like the glass, it is the most high-grade in the jade, but it also has high and low mid-range points, such as the glass of the new pit. The glass of the new field is the most representative of the grinding sand, although it is called glass, but the value is not high. Old pit glass species Guanyin:
2, ice: transparency and water head slightly next to the glass species, as the name suggests, as transparent as ice, high quality are often sold as glass species, belonging to high-end jade, there are high school and low-end points.
3, oil green
Oil Breeding Jadeite refers to a darker green type. The color is not pure green. It is gray or with some blue color, so it is not bright enough. Its color can be from light to deep. Because its surface is shiny like grease, it is called Oil green, according to the degree of transparency is also divided into high, medium and low.
4, hail / 糯 species
The texture is between transparent and opaque, like cooked glutinous rice, and the texture of the ice is also very beautiful. The same is high, medium and low.
5, flower green
Anthocyanin refers to a jadeite with a green vein and a very irregular shape, characterized by irregular green distribution. Its background color is light green or other colors, the texture can be coarse or thin, such as the bottom of the bean, the structure of the grain is thicker, called the bottom of the bean, irregular color, sometimes densely distributed, may be sparse, deep It can also be shallow, and this type of jade is therefore called a flower green. The flower green is divided into two parts: the bean bottom flower green, the horse flower green, and the oil bottom flower blue.
7, white background green
The white-green species is widely distributed in Burmese jade. The characteristic is that the background color is generally white. Of course, there are sometimes some impurities. The green color of the white-green is more vivid, and the white color is more green and white. Most of the green parts are clumpy, and these are different from the green ones. Most of the greens on white are opaque, but they are also more transparent.
8, Hibiscus species: the color is generally pale green, without yellow, very elegant, can not see the boundaries of the obvious fiber particles, although not transparent, but warm and elegant, there is a kind of refined beauty.
9, gold silk species
The golden silk species refers to the color distribution of jadeite in a filamentous arrangement, which is arranged in parallel. It can be clearly seen that the green color appears intermittently in a certain direction. Of course, the green strips can be thick and thin. The grade of gold silk jade depends on the proportion of the color and green band of the green strip, and the thickness of the green strip. The color strip is thick, the proportion of the area is large, and the color is brighter. The color bands are thin and light and cheaper.
10, violet
This emerald purple is generally lighter, so named because of the purple color of the violet flower. When it is combined with other colors, it is usually called "椿", so "椿" is also purple. Purple jade can generally be divided into pink purple, solan purple, blue purple. The pink-purple texture is relatively thin, and the transparency is better. The eggplant purple is less frequent; the blue-violet is generally coarser in texture, also known as purple bean. Purple emerald yellow light will look purple deeper, be careful when shopping. Emeralds with deep purple, fine texture and high transparency are hard to come by, so they are especially favored by Europeans and Americans.
11, bean species
Bean species is a very vivid name. Jadeite is a kind of polycrystal. If the crystals that make up the jadeite are thicker, if it is larger than one millimeter, it will be easily seen by the naked eye. The thick emerald crystals are mostly short columns. When the boundaries of these short columnar crystals are clear, they look like a grain of green beans, so they are called beans. "Ten Qing Jiu Bean" is the extensive nature of the beans. Bean species are further divided into: sugar beans, ice beans, fine beans, crude beans, etc., the value of high-grade beans is also very expensive.
12, Long stone species: also known as dragon species, meaning that the combination of species and color is perfect, the base does not eat color, the color does not eat the foundation, is a more popular word recently.
13, Mo Cui
Also called Moyu, it is a precious and rare, full of mysterious, noble and high-grade jade, color is like ink, the Burmese called it "the shadow of lovers", Hong Kong and Taiwan people also call it "successful man" "Shadow", you can imagine how popular it is. Ink is actually dark green, caused by omphacite or alkaline hornblende or secondary oxides. Ink burial in the depths of the earth's surface, limited production and limited mining, the current market share of the emerald market is less than 2%, its unique hidden color features, coupled with Chinese carving art and jade culture, so it is very attractive, The water is of high quality and is of great value. Because of its close proximity to the earth's heart, the magnetic field is strong. The Feng Shui master unanimously recognizes that the ink has the function of evil spirits, anti-virus insects, and beasts, and has a magnetic field that attracts wealth. The color ranges from dark green to black, and it appears black under normal daylight or reflected light, while the transmitted light shows emerald or dark green color, heavy color, fine texture and dense particles.
14, Tielongsheng
The Longken Mine, which is also produced in Myanmar, is also known as Tianlongsheng. It is favored by people because it is green and green, but it is limited because of its poor overall transparency. This variety is divided into eight grades, with high, medium and low grades.
15, red dragonfly: red for the green, green for the green. If you encounter a good water, a positive color, especially an old pit, don't miss it.
16. Astragalus membranaceus: In the market, the value of red peony is higher than that of scutellaria, and the scutellaria is higher than brown sassafras. The price of brown sassafras is second. However, there are also cases in which the price is different from the conventional one because of the love of people and the unique characteristics of the accessories.
17, è—• powder type jade: its texture is as fine as glutinous powder, the color is light pink purple (light spring), is a good crafts.
