Hetian jade, commonly known as true jade, a variety of nephrite, traditional concepts specifically refer to jade produced in Hetian areas in Xinjiang. Hotan jade is mainly distributed in Kunlun Mountain in the south of the Tarim Basin. From the west of the Arazi Mountains in the east of the Tashkurgan County in the Kashgar area, the Sangla, Tiekrik Tagaga, and Lewish Tag in the southern part of the Central Hutian area, the east and the north of the south of the county in the end of the county Wing’s Sura Muming Tag. The Yulong Kashi River, the famous Baiyuhe River in ancient times.

Hetian jade, one of the “four famous jade in China” (the third is Lantian jade in Shaanxi, Liaoning Saitama, and Dushan Yu, Henan). The traditional narrow -minded category refers to the jade produced in the Hetian area of ​​Xinjiang, which is famous for its “sub -material”. Although Hetian jade is named after Xinjiang Hetian, it is not a regional concept, not specifically refers to jade produced in Hetian area, but the name of a type of product. China has named Hetian jade with more than 98%of the ingredients, all of which are within the scope of the national standard.

When Qin Shihuang unified China, Hetian Yu was called “the jade of Kunshan” because it was produced in Kunlun Mountain, and later was called “Yu Saitama” because it was located in the “Yu Guo”. It was not officially named “Hetian Jade” until the 9th year of the Guangxu of the Qing Dynasty (1883).

The famous products in Hetian jade are the “Seal of Queen”, which is treasured in the History of Shaanxi History Museum. Its texture is Xinjiang Hetian Sheep fat jade. It is the only Han Queen jade seal in the Han Dynasty. Essence In the 2008 Beijing Olympic Games Huibao “China Seal”, it also adopted Xinjiang Hetian jade as a material.

Wetian jade belongs to a metamorphic rock formed by the contact with medium -acid magma rocks. It contains multi -mineral collection such as penetrating glitter, angle glitter, and yang stone stones. The chemical formula is CA2 (mg, Fe) 5 [si8o22] (OH) 2, the density is 2.95-3.17, and the Mohs hardness is between 6.0-6.5.

For a long time, the academic community has a lot of controversy to divide Hetian jade according to the place of production or according to the mineral composition. On December 17, 2013 and January 2014, the National Standard Management Committee and the National Standard Sample Technology Committee approved the release and released the release. National Standard GSB 16-3061-2013 “Hetian jade physical standard sample”, officially determined- “The national standard of Hetian jade samples, regardless of its origin, will be defined according to its mineral composition.”

Mineral composition

Hetian jade is a showerite jade, and the calcium flashes of the flashes of the flaspite of flaspite are a member of the minerals in the minerals of the shonel iron sun stone. The chemical formula is: CA2 (Mg, Fe) 5 [ SI8O22] (OH) 2, magnesium and iron can be replaced by a complete class quality.

In this series of minerals, (CA+NA) B≥1.34, NAB <0.67; (Na+K) A <0.5, SI ≥ 7.50. Based on the “Corporal Flash Naming Plan” recommended by the International Mineral Mineral and Mineral Naming Committee approved by the Cape Stone Branch, the division of the glitter and the sunstone in the units Different level ratio is named:

Mg/(mg+Fe) = 0.90-1.00, called transparent flashes

Mg/(mg+Fe) = 0.50-0.90, called Yangqi Stone

Mg/(mg+Fe) = 0.00-0.50, known as Tieyang Qi Stone

In addition, when Si <7.50 to Si ≥ 7.25 is called the flaspite of the flaspite, the light -ranging stone, and the iron flashes of the shiny stone, and the iron flashes. In addition, there will be a small amount of aluminum (AL) instead of mg and Fe in the flaspy stone -lined stone mineral.

The characteristics of Hetian jade in minerals are mainly:

(1) Passele of glitter minerals above 95%

Among them, the white jade is 99%, the blue and white jade is 98%, and the green jade is 97%(95-99%). The content of Hetian Jade Polytite in the same type of flashed stone jade is high.

(2) There are very few impurities minerals

Generally, 1%-3%, mostly about 1%. Mine, magnesium iron spinels, phosphorusite, etc. There is no sunstone, which is different from the penetrated flashes produced in ultra -magnesium iron rocks.

中华奇石丨新疆——和田玉:解析

(3) Minerals are extremely fine

For the microcystal and hidden crystals, the permeable glitter minerals are fiber, needle, and blades under the polarized microscope. Under the transmission electron microscope, it is long -column, short -columnar, and fiber -shaped. According to some samples, the granularity under the electron microscope is: short column shape is 0.0046 mm × 0.0013 mm, 0.0063 mm × 0.0036 mm, length and width ratio is 2: 1 or 3: 1; long column -shaped is 0.01 mm × 0.0028 mm, 0.004 mm of 0.004 mm × 0.0008 mm, 0.012 mm × 0.0012 mm, length and width ratio is 3: 1 or 5: 1, 10: 1; fiber -shaped is 0.0004 mm × 0.000021 mm, 0.0021 mm × 0.00007 mm, and the length ratio is 20: 1 or 30 30 :1. The fineness of the granularity is rare among similar flash stones. Crystal cell parameters are: A0 = 0.985-0.987 nanometer, B0 = 1.800-1.805 nanometer, C0 = 0.531-0.532 nanometer, U = 105.03 ° -105.10 °.

中华奇石丨新疆——和田玉:解析

(4) The structure is based on felt -like

The particle size is uniform, and it is generally intertwined into a felt blanket. This is an important reason for delicate texture, and this structure is rare in other jade.

chemical composition

Polyaldite is a water-containing calcium iron magnesium silicate. Since Hetian jade mineral is basically composed of transparent glitter, its main chemical composition is close to the theoretical value of transparent glitter: SiO253.34%-57.60%, MGO21.30 %-24.99%, CAO11.33%-17.41%(theoretical values ​​of transparent glitter are SIO259.169%, MGO24.808%. Cao13.805%, and Baiyu is closer to theoretical value, and the secondary component content is small).

中华奇石丨新疆——和田玉:解析

Generally speaking, Feo is less than 2%, Fe2O3 is less than 1%, NA2O and K2O are less than 0.3%, AL2O3 is less than 2%, and H2O is less than 2%. The FEO content increases with white jade to jade. Average: White jade is 0.72%. The jade is 1.94%.

The sparkling stone jade in Hetian jade and magnesium iron supermine rocks is mainly in the chemical composition of the FEO. The former is low, and the latter is high. It is 2.93%-5.44%; followed by different trace elements, the latter has chromium, nickel, etc., but the former has no.

The name of Hetian jade today does not have the significance of the place of production in national standards, that is, regardless of whether it is produced in Xinjiang, Qinghai, Liaoning, Russia, Canada, and South Korea, its main component is that it can be called Hetian jade.

Folding stitch system

Hotan jade mainly forms minerals and littering stones, all of which are single oblique crystals. The common crystals of these two minerals are long columnar, fiber, and leaf -shaped. Hotan jade is a collection of these fibrous minerals.

Folding structure

The main structure of Hetian jade is the transgence structure, including felt -like crystal crystal structure, micro -fiber -hidden crystal structure, micro -fiber transformer structure, micro -micro crystal crystal structure, micro -microcele Switching crystal structure and microscopic radiation (broom -like) crystal structure. Secondly, it also includes uncommon residual structures and explanation coronary structures;

Although the Hetian jade mineral particles have a certain orientation, they are not strong, and occasionally the particles have wave -like lighting phenomenon and plastic deformation. These indicate that the stress intensity of the deterioration is within the elasticity limit of the mineral;

The main structure of Hetian jade includes block structure and chip structure, which is more common in block structure.

Mineral composition feature

Hotan jade is basically composed of the micro -crystal one -hidden crystal collection of light -transparentite. According to the mineral component and its expression form, it can be divided into microfiber -shaped glitter, sheet crystal flaspite, and impurities minerals. 3 parts.

The vast majority of the micro-fiber-shaped light-like flaspite parts, with a general content of 80%-90%or higher. The higher the content, the more detailed the structure. Micro -fiber -shaped flaspite can be divided into hidden crystal parts, non -fixed -directional micro -fiber scales, near parallel fibrous bundles, and radiation -shaped (broom -like) fiber groups according to their shape and size.

(1) Cultivation of crystal: The particle size and form of the glitter cannot be distinguished under the microscope. It exists in the form of a matrix.

(2) No fixed -directional micro -fiber scales: A collection of macro -intensive macroex fiber cluttered by the pheasant flashes. The size is unpredictable under the microscope, but the shape can be roughly distinguished according to the lighting phenomenon.

(3) Nearly parallel fibrous bundles: Passionate fibers are arranged in parallel along the long shaft, and the lighting direction parallel is parallel to the fiber extension direction.

(4) Radial -like (broom -like) fiber group: Cluster -like fiber transparent flashes are distributed in radiation -shaped, with a weak wave -like lighting phenomenon.

The chip crystal peeling stone generally appears in a single piece of flaspace, 0.05-0.20 mm long, and between 0.01-0.02-0.05 mm. Sometimes it will be larger. 3: 1-5: 1. It is often not the main composition in Hetian jade, accounting for about 10%-20%, and the content of the Hetian jade is weakened or destroyed. When observing Hetian jade with the naked eye, the transparent transparency of the transparency and transparency on the base have opaque and slightly milky white tone, different forms of spots, that is, the large particles of the crystal shock flashes, as if the residual seen in the condensed rice soup seen The cooked rice grains are commonly known as “soup” or “stone” in craftsmanship.

中华奇石丨新疆——和田玉:解析

Impoos are small, generally the individual appears, and the total amount is not more than 1%. There is also a certain regularity: in the white jade, there are phosphorus 灰 and magnetite and a small amount of eaves. The general particle size of aphamium is about 0.025 mm, the magnetite is about 0.01 mm, and the size of the cabinet stone changes. The range is large. The phosphorusstone can see its typical six -square column horizontal cutting surface in the mirror, indicating that the degree of self -shape is better. Magnetic ore is self -shape or semi -self -shaped. Tongshi is brownish yellow under a single polarization, with weak and poly color, and poor self -shape. Under the orthogonal polarity, the color of the mineral itself is generally several grains. In addition to individual limestone and magnetite, impurities minerals in green jade also have oblique curtain stone and trace graphite. The impurities in green and white jade are mainly white jade, and sometimes the mineral impurities with green jade.

Rock structure characteristics

中华奇石丨新疆——和田玉:解析

The main structure of Hetian jade has the following 6 types:

中华奇石丨新疆——和田玉:解析

(1) felt -like crystal crystal structure: This is the most typical structure of Hetian jade. It is manifested as: the granular granules are very subtle. The particle size cannot distinguish its contour under the optical microscope. Hetian jade with this structure is refined and dense, which is the characteristic of high -quality Hetian jade. This structure can be seen in white jade, green white jade, green jade, and ink jade, which is closely related to Hetian jade texture.

(2) Micro -fiber -hidden crystal structure: refers to the structure composed of fiber -shaped flaspite and hidden crystal permeability, in which the fiber -shaped flaspite is weakly arranged in a weak orientation.

(3) Micro fiber transgence structure: The flaspite is mostly fibrous, and it is generally parallel to distribution.

(4) Microcrystalline crystal structure: refers to the structure composed of chip -shaped glitter and hidden crystal fluorite. Among them, the content of chip -like glutinous glutinous glutinous glutinous glutinous gluten is not high and has a weak orientation. When observing the hand specimen with the naked eye, the flake -like flaspystone is manifested as spots of impurities; if a large number of existence, it will affect the quality of jade and need to be removed when pondering. Therefore, the jade texture of the structure of the structure is generally poor.

(5) Micro -micro -crystal structure: The splitstone particles are distributed with leaves, and the jade texture with the structure is generally thicker and even has no economic value.

(6) Radial or broom -like crystal structure: This structure is less in Hetian jade. It is another manifestation of the fiber crystal structure. Extinction. Inference may be that under the condition of thermal deterioration of the water solution, the lightning stone has grown rapidly around the center, and the crystallization becomes radial.

In addition, Hetian Yu also has the following uncommon explanatory residual structure:

(1) Residual structure: The residual minerals wrapped in spots or transgence -transparent glitter are connected to the inside and outside of the remaining layer of residual minerals in the substrate. This structure shows that the heavy crystals of spots or metamorphic minerals have not fully absorbed and eliminated the corresponding components of the original rock, and formed in an environment with poor stress and inadequate response. Conditions provide effective evidence.

(2) Explanation of the coronary structure: It is manifested as a shelter -like flashing stone along the edge of the crystal of the white cloud stone wreckage, which proves that the white cloudstone is involved in the participation of the water -containing solution. Rate jade, that is, white cloud stone+5102+hzo (steam)+transparent glitter.

structure

The structure of Hetian jade refers to the interdependence and cooperation of the size, shape and space of the mineral set. Regarding the structure of Hetian jade, in ancient times, “filled with chestnuts” was called, and the same is the same as the modern “density”.

(1) Block -like structure: The most common structure of Hetian jade, Hotan jade is the dense block, the structure is uniform, and the Hetian jade with this structure has a felt -like micro -intersecting structure, a fiber crystal structure, and a sheet -shaped crystal structure.

(2) Listed structure: Hetian jade is forming, which is formed by the later structural stress, and the jade with this structure cannot be used.

Optical nature

(1) Color: Hetian jade is very rich in color, including white, cyan, gray, light to dark green, yellow to brown, ink color, etc. When the main composition of Hetian jade is white, Hetian jade is white. Because Hetian jade’s chemical composition contains Mg, as the FE paid the same elephant with the same elephant in the mg in the flaspite molecule, Hetian jade can be different in green. The higher the FE content, the deeper the green color of Hetian jade. When the sparkling stone in Hetian jade contains fine graphite, it becomes Mo Yu.

(2) Gloss: It is the reflection ability of jade to light. Due to the different texture of various jade, different hardness, and the degree of absorption and reflection of light, the gloss is also different. Hetian jade can be grease, wax -like luster or glass luster. The grease is soft, not strong or weak, making people look comfortable and touching. Generally speaking, the texture of jade is pure and luster is better; if there are many impurities, the luster is weak. Generally, the value of the luster is high, and the value of those with dry gloss will be reduced.

中华奇石丨新疆——和田玉:解析

(3) Transparency: Refers to the performance of light through light. Hotan jade is translucent to opaque, most of which are slightly transparent, and very few are translucent. There are three factors affecting transparency. One is the strength of light, the other is the thickness of jade, and the third is that jade absorbs strong weakness to light.

(4) Refractive index: The refractive index of Hetian jade is 1.606-1.632 (+0.009, -0.006). Because it belongs to the mineral collection material, it is rarely read at the same time. 1.60-1.61 can see a vague shadow boundary. Light characteristics: non -average collection.

(5) Absorption spectrum: Hetian jade is rare to absorb lines, which can have fuzzy absorption lines or absorption bands at 500 nanometer, 498 nanometer and 460nm; there is a absorption line in 509 nanometers; The absorption line.

(6) Luminousness: UV ravness is fluorescent inert, and generally does not glow.

中华奇石丨新疆——和田玉:解析

Mechanical nature

中华奇石丨新疆——和田玉:解析

(1) The density is generally 2.95 (+0.15, -0.05) gram/cubic centimeter.

中华奇石丨新疆——和田玉:解析

(2) Hardness: Hardness refers to the ability to resist the abroad, scratches, and grinding, and is one of the important signs of identifying Hetian jade. The hardness is high, the jade is polished, the brightness is good, and it can be stored for a long time. The hardness of Hetian jade is 6.0-6.5. Due to the different structures, there will be some changes. Generally speaking, the sapphire hardness of the same origin is slightly greater than white jade. In the past, the craft industry has been divided into low and high -end jade in the past. Hardness is an important indicator. Generally speaking, high -end jade has a large hardness and low -end jade hardness. The hardness of the glass is 5-5.6, and Hetian jade scratches the glass will leave obvious scratches, but Hetian jade will not be scratched at all. This is also an important feature of identifying Hetian jade.

(3) Toughness: It is the ability to resist abrasion, stretching, stress resistance, etc., and can also be called anti -rupture ability. The so -called toughness means that the object is difficult to rupture and wear resistance. Among all gems in the world, Hetian jade is extremely tough, second only to black diamond, and is the most common toughness in the breed of treasure jade. Hetian Yu has such a great toughness that is inseparable from its unique felt structure.

(4) Lifting and fracture: Under the action of external forces, the crystals are cracking into a smooth plane properties along the specific crystallization direction (generally parallel crystal surface direction). noodle. The difficulty of formulating the understanding and the development characteristics of the formation of gemstones will be divided into four categories: very complete syndrome, complete explanation, medium understanding, and incomplete understanding.

The flaspite has two sets of complete explanation. Since Hetian jade is a mineral set, the overall expulsion surface is not seen, and the fracture is different. Popular understanding is that when people collect jade, they will find that there are many cracks on the surface of the jade. The professional terms talk about the cracking texture of the jade as the phrase. Due to the influence of the crystal heterogeneous, jade deposits have uneven cracks, which has an impact on the carving of jade articles. The diarrhea surface is not a broken surface. There is no certain direction and laws in crushing, and there is a regular crack in a regular surface in one or more directions, and the surface also looks smooth and smooth.

Optical effect

The so -called nephrite cat’s eyes are sometimes called Yangqi stone cat eyes. It is a collection of yang -like stones or solid solid solid solids arranged in parallel or solid solids, which has a good cat eye effect.

Land classification

According to the national standard GB/T16552-2003 “Jewelry and Jade Name”, Hetian jade has no meaning of origin, that is, the nephrite with the main mineral as the flaspite can be called Hetian jade, and Hetian jade can also be called nephrite jade. Essence

Except for Xinjiang, China, there are more than 120 flashes of flashes of flaspites in the world, distributed in more than 20 countries and regions: Russia, the United States, Brazil, Canada, Australia, Poland, New Zealand, South Korea, North Korea, Taiwan, etc. Output is the second place in the world. These minerals are snake -like rocky -type flaspy stone jade, mainly jasper, Russia, South Korea, and North Korea produced white jade. Only the Hetian jade in Xinjiang belongs to non -snake -patterned rocky jade because of special geology.

Category

Hetian jade is classified according to the output environment, which can be divided into native ore: mountain material; secondary mines: mountain flowing water, sub -material, Gobi material.

中华奇石丨新疆——和田玉:解析

The output environment of different production areas has its own characteristics. Therefore, the quality of Hetian jade will be different. In the same level, Ziyu has the best quality, the highest value, and the mountains and rivers.

Color pattern

Compared with other regions of domestic and foreign areas, Hetian jade has a lot of color tones and its own series. Secondly, Hetian jade has rare white jade in the world, especially the white jade like sheep fat is unique to Hetian jade, which is extremely valuable; again , Hetian jade has a skin color. Many jade in the world have skin colors, but it is better to be beautiful in Hetian jade. In ancient China, the color of Hetian jade attached great importance to it. It was not only an important symbol of quality, but also contained in a certain ideological connotation. The ancients may be affected by the five elements, and five -color jade is allocated according to the Quartet and the central government. The east is green, the south is red, the west is white, the north is black, and the central government is yellow. In ancient times, the five colors of green, red, yellow, white, and black were used as the right color, and the others were colorful, which divided the jade into five colors. However, Hetian Yu actually has only four main colors: white, green, ink, and yellow. In addition, jasper is also produced in the Kunlun Mountains and Alkina.

In Hetian jade, Baiyu is the most precious. The best one in Baiyu is sheep fat and white jade, which is the top of jade. Sheep fat and white jade are characterized by white, transparent, thin, and moisturizing. Because Huang Yu is very small, the colorful and moist chicken oil yellow is not under white jade.

According to the national standard samples, Hetian jade is divided into 6 large categories: white jade, green white jade, green jade, jasper, ink jade and sugar jade, each category has reference standards.

Traditional categories are divided into 8 categories based on color patterns: white jade, blue jade, green jade, jasper, yellow jade, ink jade, sugar jade and flower jade.

Jade characteristics

texture

The texture is a comprehensive manifestation of jade quality, including shape, moisturizing, cracks, impurities, and so on. Hetian jade’s mineral composition determines its excellent texture:

(1) Because of its extremely thin particle size, the texture is very delicate. It is the so -called “meticulous and shudder” of the ancients, which is not enough for other jade.

中华奇石丨新疆——和田玉:解析

(2) Wen Run Zize. That is, it has the grease luster, giving people a sense of moisturizing and softness. The ancients so -called “moist and moist”, and sheep fat jade is famous for moisturizing as sheep fat.

(3) There is moderate transparency. That is, “the water head is good”, which is slightly transparent. The jade parts of the jade appear to be watery and angry.

(4) There are very few impurities. Some reaches flawlessness, and the same is consistent inside and outside. It is the so -called “flaws that do not hide Yu, Yu does not hide the flaws”, or “gills are from outside, you can know”.

hardness

Hardness is one of the important signs of identifying Hetian jade. It refers to the ability of minerals to resist foreign machinery (such as portrayal, crushing, grinding, etc.). hardness. The jewelry industry generally regards hardness as an important symbol to divide gems and jade. The hardness of the gem is generally more than 7 degrees of Mobi, and the hardness of jade is generally 4-7 degrees of Mobic, and Moh is usually called colorful or carved stone below 4 degrees. Hardness, good polishing, can make jade wares brighten, and it is also convenient for long -term preservation.

The Hetian Yu Jing measured that Mo’s hardness was 6.5-6.9, which was relatively hard, and different varieties were slightly different. Generally speaking, jade hardness is slightly greater than white jade.

tenacity

Toughness is usually the ability to combine jade, that is, the resistance to external pressure or fragmentation. The characteristics of toughness are not easy to break and wear. Religious jade is very tough, which is characterized by other jade, and can be used as a fine craft.

中华奇石丨新疆——和田玉:解析

Of the common gems, the toughness of black diamond is 10, the sparkling stone jade is 9, emerald, ruby, sapphire are 8, diamond, crystal, and sea sapphire are 7-7.5, olives are 6, emerald green is 5.5, yellow crystal is yellow, yellow crystal, yellow crystal, yellow crystal, yellow crystal, yellow crystal, yellow crystal , Moonstone is 5, cat eye stones are 3, fluorite is 2. For example, the toughness of the showerite jade is 1000, the relative toughness of other jade or minerals is: Emerald 500, snake pattern (such as sauce jade) 250, quartz rock 10-20, quartz 5, Gangyu 2-3, Yunmu 2. It can be seen that the toughness of the sparkling stone jade is the largest in jade, and its pressure resistance can exceed steel. After scientific testing, the compressive strength of Chinese carbon steel is 1600 kg/square centimeter, while Hetian jade’s compressive strength can reach up to 6541 kg/square centimeters.

Hetian Yu has such a large toughness that is inseparable from its unique felt structure. The toughness is not easy to break, but also wear -resistant, which has great benefits for the artistic shape and sculptures of jade articles. This is an important factor for Hetian Jade as the hero of jade.

color

Color is not only an important criterion for evaluating the quality of Huta Jade, but also the main basis for dividing the types of Hetian jade.

Compared with the nephrite in other parts of domestic and foreign areas, Hetian jade’s color has more colors and its own series. The color of the glittering shiny jade in the world is basically five colors: white, green, yellow, black, and blue (green), and there are some intermediate transition colors. Due to the low iron content, Hetian jade is basically the first four colors, and the Hetian jade is basically the first four colors, and Ultra -magnesium iron rocks have high iron jade with high iron, basically green, that is, jasper. According to the color, Hetian jade is divided into four categories: white jade, green jade, yellow jade, and ink jade. Among them, it can be further divided. Guoyu, white jade, blue and white jade, etc., Kunlun Mountain and River also produces jasper, but the native mine is a ultra -magnesium iron rock type, so it should not be included in Hetian jade. : “Huang Ru steaming millet, white as fat, black as pure paint, which is called jade.” Especially the sheep fat in Hetian jade is rare, only Xinjiang produced. , Bai Yu’s color is the most expensive. “

Another characteristic of Hotan Yu is that there are jade. The ancients attached great importance to the jade. There are those who have a flawless definition in the vertical and horizontal ruler, the ancient emperor took the seal, the so -called lingering city was not easy to get, and the fifty or six inches of flawless definition, the cure of the cup, this is the most important treasure, “Hetian Yusuyu’s skin skin leather’s skin’s skin’s outer skin , According to the characteristics, it can be divided into three types: color skin, sugar skin, and stone skin. The skin is a layer of yellow or brown skin (about 1 mm thick). The quality of jade, such as Akiko, tiger skin, deer skin, etc., is often the superior white jade. The skin of sugar jade is thicker, such as brown sugar, and the last jade mine often has such jade, including white jade or blue jade, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone, stone The skin is a stone surrounding rock in the outer layer. After taking the surrounding rock, you can get jade.

transparency

The transparency is the degree of visible light through jade, which is mainly related to the strong and weakness of the light absorption of jade. Mineralology is generally divided into three types: transparent, translucent, and opaque. The appraisal transparency should polish the jade, and at a certain thickness, the perspective of other objects should be divided into 4 levels: transparent body, translucent body, micro -transparent body, and non -transparent body. Hotan jade is slightly translucent. Under the general progress, it can pass through, but it cannot see through the image.

Generally speaking, highly transparentness is also called water head and foot. Although the water head can set the texture and color of the jade, not all those with high transparency are good jade. Hetian Yu belongs to translucent-slightly transparent under general thickness. Although it can pass through the light, it cannot see the object. This transparency enhances the warmth of Hetian jade gloss, so Hetian jade should not be too thin when carving.

中华奇石丨新疆——和田玉:解析

luster

Gloss is the ability of jade to reflect light. Hetian jade luster belongs to the grease and luster. This gloss is soft, not strong and weak, that is, there is no light inspiration of strong light, and there is no wax texture of weak light. The ancients called the Hetian jade “gentle and moist”, which is its luster with a very important oil, giving people a moisturizing feeling, especially the sheep fat jade in Hetian jade is because of the moisturizing luster like sheep’s fat. famous.

Gloss is an important basis for evaluating the texture of Hetian jade. Generally, the value of those who are oily and oily, and those with dry gloss will be reduced.

中华奇石丨新疆——和田玉:解析

sound

The sound of jade after the blow is an important nature of the ancients to identify jade.

中华奇石丨新疆——和田玉:解析

The jade made made by Hetian jade, the sound of the sound when knocking is cleared, such as the sound of the golden cricket, the rejuvenation is absolutely, the sound of the disabled is far away, and it is Xuandang. , The more the sound is long, and the end of it. “This characteristic, other non -glittering stone jade is inferior.
