Jade Knowledge: Demystifying industry terms you don't know

1, look more and buy less

For the purchase of jade original stone, “see more” is a process of choice; it is a process of comparison; it is also a process of accumulating and verifying experience; it is the premise of “buying”. “Buy less” is not to buy, but to remind you to “see” and buy again.

2, the dragon has water everywhere

The so-called "dragon" actually refers to the green in the jade. That is to say: under normal circumstances, no matter the thickness or transparency of the texture, the green part is better than the green part. Of course, sometimes this difference between emerald green and the ground is too strong, as the next maxim says.

3, shine

Photographing refers to the mutual printing and dyeing relationship or coordination between green and earth, water, etc. in jade. The color and the "water" and "land" are well coordinated to reflect the brilliance, luster and value of the jade. It is called "spirit", and it is called "death". The performance of the emerald is exquisite, the color is rich, the color is even, the clarity is high, the head is good, and the value is high.

4, green

Cui nature refers to the cleavage plane or crystal plane of the monoclinic pyroxene in the jade. The reflection of light appears to be flake, needle or star-shaped flash. This phenomenon becomes "green". Insiders are often vividly described as mosquito wings and fly wings. In general, the coarser the clinopyroxene particles, the easier it is to observe.

5, steel

Steelity means that some jadeite textures are very delicate and compact, and after polishing, the reflection is very strong, like the surface of steel.

6, pit

The pit is a relatively vague concept. It originated from the mining pit. Some literatures describe it as the time when the jade is buried in the ground. The old pit is called the old pit, the new one is called the new pit, and the old pit jade is of good quality. The quality of the new pit jade is poor. This statement is actually not scientific, and how scientific expression needs to be explored.

7, leather

The skin refers to the skin shell formed by the weathering of the secondary jade raw materials in the process of flowing water or natural force handling. The color of the skin is black, gray, yellow, brown, light yellow, white and other colors. According to the characteristics of the jade skin, the quality of the interior of the jadeite can be roughly estimated. For example, the skin is dense and fine, which usually shows that the interior is good; the surface of the skin has an indistinct moss, which often indicates that there may be green inside.

8, cut

The processing of jade products is divided into two categories: finished products and finished products. Light body products require high raw materials and can not be cracked, because it is easy to see when there is a crack. Cracked jade, mostly used to make flower pieces, can be used to cover up cracks by engraving. Therefore, in the evaluation of the finished body and flower parts, in the case of the same quality, the light body products are more expensive than the flower carvings, of course, there are exceptionally exquisite carving jade.

9, the water

The effluent is the last process of jade polishing, which is the final polishing process. It is often polished with a leather belt, and she is bright and shiny.

10, no flaws, no flowers

"Book of Rites" cloud: "Dagui is not awkward, beauty is also good." In fact, high-end jade green is usually in the form of "su", to express its natural essence. For example, moving fingers, fistulas, and the like in the old goods belong to the “Su-Li”. If you have a pattern, you will have a flaw in the beautiful pattern. Therefore, there is a saying in the industry that there is "nothing to hide". The same is true in modern jadeite products.


Jade noun explanation

1. What is brick, flower, and color?

Brick heading refers to some jade materials with poor transparency, many impurities, colored green or no green. Bricks are usually only used in low-grade raw materials for general tourist crafts in kilograms.

Flower material refers to some mid-range jade materials with green, green, certain head or no green but good water.

The colorant refers to the high-grade and high-grade jade raw materials. Can do high-end ring face, bracelets and other accessories. The giant jadeite material with large green color is also called color material. Bricks or flower materials and pigments will change during the betting process. Sometimes an inconspicuous brick material will appear green after a cut, and a piece of color will look good, but it cannot be cut after cutting. It is also common to do high-end jewelry.

"Spring Ribbon"

2. What is spring belt color?

Spring refers to the fuchsia jade. Purple jade is also called violet. The color represents pure green. Spring color refers to a piece of jade or a piece of jade jewelry with purple and green. The jadeite material that is currently in the spring is very rare. On the high-grade Kaisu raw materials from 1991 to 1992, there were raw materials with purple, green and water, but they were dug in half a year. Good spring color jadeite is of high value.

3. What is colorful jade?

Colorful jade is called multicolored jade on a piece of jadeite or on jade jewelry. Such as green, purple, blue, white, etc., in the evaluation, among other things, mainly depends on the amount of green and the quality of water as the main conditions. If green accounts for a large proportion and the water is good, this colorful jade is very valuable.

4. What is Ba Sanyu?

Eighty-three jade refers to a new factory jadeite that appeared in the jadeite production area in Myanmar in 1983. It is a kind of minimum grade brick material with dry water, poor bottom structure and loose structure and coarse crystal. All of the B goods or dyed jade used for jadeite are useless jadeite materials without manual treatment. It is a variety of jadeite, and its mineral composition and physical optics are the same as normal jade. Because of its loose structure and coarse crystals, it is easy to change its transparency after being treated with acid, and it is easy to be filled with color. After treatment, the water is better, the waste is used, and the price is low. The San Sanyu should be treated correctly.

5. What are the three elements of physics in jade?

Almost all the jade in the world have data that can explain their identity. These data lock their identity, which is the three elements of their physics. The world's precious gemstones rarely have the same three elements of physics. This is hardness, specific gravity <density> and refractive index. The jadeite has a hardness of 6.5 to 7, a specific gravity (density) of 333, and a refractive index of 1.66. Secondly, there are characteristics such as toughness, cleavage, fracture, color, dispersion, transparency, luster, and optical rotation.


6. What is Tielongsheng?

It mainly refers to a kind of jadeite with a green color, a dense structure and a poor water head, which is composed of a chrome-rich jadeite mineral aggregate. The main minerals are jadeite accounting for more than 95%, followed by chromium, town, calcium, iron and so on. The degree, specific gravity and refractive index are the same as jadeite, which is a variety of jadeite. When its specific gravity, hardness and refractive index are different from jadeite, it indicates that the content of other minerals in it increases, and it is not a jadeite variety. It has been used to make thin ornaments in ancient times, which is very beautiful.

7. What is oily?

Oil green is a delicate, transparent and oily jade. There are two types, one of which is dark blue, the water is very good, and the light is blue and gray, without green. The second is a blue-green tone, the green light is under the light, and the water is good. By analyzing the former oil jadeite without chromium, it contains more than 1% of divalent iron ions. The latter oily jadeite contains traces of chromium and iron.

In addition, there is also a kind of "Jade" called "Jade", which has the same color as the dark green water, but the hardness is only 5.5~6. The specific gravity and refractive index are very different from those of jadeite. The main contains omphacite, the second is jadeite, does not contain chrome, but contains iron, should be called omphacite jade or omphacite jade.

8. What is the jade dragon species or god species?

Dragon species or god species means that the green color of the jade is completely dissolved in the "ground", the green is uniform, and the color "ground" is coordinated. The color is not thick and not light, and no color roots are seen. From the "land" of the jadeite, the bright and beautiful Huaguimei is revealed, which is the highest quality variety of jadeite.

Emerald root

9. What is the color root of jade?

On a piece of all-green jade jewelry, see a little bit or a thin strip of slightly darker green, this slightly deeper green transitions to a relatively shallow green inner color root. The color root is a sign to judge the authenticity of the emerald green, but the high-grade extra-grade jade, the green is very uniform, there is no depth, there is no color root, and the more color roots affect its quality and price. Therefore, it should be considered comprehensively in the evaluation.

10. What is the door open?

Opening the door is also called opening the skylight. Because the jadeite raw material is wrapped in a layer of skin, I don't know if it is good or bad. Therefore, it is necessary to cut a piece of raw material for observation, which is called opening the door. Rubbing the mouth with a sickle or sand on the emerald to wipe off the skin, revealing the jade to observe its quality. However, the incision or the rubbing mouth is a local part of the jadeite. It cannot explain the whole of the jadeite and has great risks. It is a very high technique to estimate the quality of the inside from the local opening, whether there is green or not.

11. What is the place of jade?

The entrance is the origin of the jade. The Myanmar jade production area is also called the mining area or the field area. It is divided into six areas, each of which is divided into many places. The jadeite produced in each field has its own characteristics of appearance, quality and color. According to the particularity of the emerald in the field, observe whether the jade can be gambled. The field is divided into the old field, the new field and the new and old areas. The six fields are:

Old field area (also known as old pit old factory)

1 Afraid of the field, the famous venue has more than 28 venues such as Gray Card, Mu Na, Otani, Sitong Card and Pagang.

2 Mukanchang area, famous venues have more than 14 fields such as Damukan, Finch C, and Huangba.

3 Nanqichang District, there are 9 venues such as Nanqi and Mohan in the famous venue.

4 Houjiangchang District, there are more than 5 venues such as Houjiang, Leifang, Gamo and Moshou Guo.

Xinchang District, (also known as Xinkeng New Plant)

5 New venues, famous venues include Masa Factory, Kaisu, Duwei, and Miaogang.

New and old field, also known as new and old factory

6 new and old venues, the famous venue has Longtangchangkou and so on.

12. What is the new pit of the jade?

The old pit is also called the old factory. The new pit is also called the new factory or the new factory jade. In the jade mine, the jadeite that has been deposited and deposited by the river water is called the old pit old factory. Those "original rocks" are also called rooting stones called the new pit new plant. In the mines, the new pits are generally called the old pits, and the inland areas outside the mines are also called new species or old species, which can be accurately identified by the naked eye. The quality of the old pit is good and the quality of the new pit is poor.

13. What is Malay jade?

Also known as Malaysian jade, Lu Songyu and so on. It is a kind of artificial imitation jadeite product. The main mineral is quartz, which is made by adding a coloring agent to pure quartz or quartz crystal. The hardness is 6.5~7, the specific gravity is 2.65, and the refractive index is 154. It was popular in 1988 in Thailand, Myanmar and the Yunnan border. At the beginning, many people were deceived, and some people squandered for Malay. The sales were good. In the middle and late period, the unscrupulous merchants called the green quartzite, the Australian jade, the Dongling jade and the green glass all known as Malay jade. It can be accurately judged with the naked eye.

14. What is water foam?

Contrast view of the water foam jade Buddha and jade jade Buddha (left is water foam, right is ice jade)

The Chinese-Myanmar border often sees white, transparent jade, which often comes with blue or blue-green flowers. The coloring matter of the water foam is an actinolite and an epidote in a certain direction. More white cotton, water is very good. The overall color is gray or white. The mineral composition is mainly feldspar, which can be called feldspar jade. The secondary minerals are jadeite, omphacite and diopside. The hardness is 55~6, the specific gravity is 2.56~2.64, and the refractive index is 1.52~1.53.

Uncover the secrets of gambling stones to make fake tricks:

Gambling stones or gambling goods means that when the jade is mined, there is a layer of weathered leather wrapped around it. It is impossible to know the good or bad inside. The jade that must be cut is called gambling stone. The jadeite produced by the old factory has skin, but the water stone jade produced in the riverbed is also the old factory jade, and the skin is very thin or skinless. Most of the jadeite produced in the new factory is skinless, but it is produced in the slope layer. The thickness and thickness of the skin mainly depend on the degree of weathering, and the degree of weathering is high. The surface of a piece of jadeite is colored and the surface is very good. When you cut the first knife, you see green, but when you cut the second knife, there is no green. This is also a common thing. Wherever you leave the emerald mine, the gambling increase is only one in ten thousand (referred to as color material), and the chance of gambling in the jade mine is much higher. The gambling rose a jade and became rich overnight, but the vast majority ended in failure. Advice to play jade gambling stones should be cautious.

Therefore, some unscrupulous businessmen seek profiteering, use unscrupulous methods, confuse their minds, set up scams, and use unexpected methods to make fake tactics. Many people are deceived and even ruined. The common methods of doing fakes are as follows:

Transfer flower: This is a jade cut on the poor quality jade and transplanted at the incision with the size of the incision, the texture is fine, the color is beautiful, and the good quality is used to cover the overall bad quality. In the identification, it is necessary to pay attention to the sand in the lower part of the incision and the sand on the mother. The lower part of the incision is generally loose sand, which cannot be granulated, and the sand of the mother is mostly granular. If the whole is different from the sand in the lower part of the incision, then pay attention.

Escape from the dead: A good-looking gambling stone, unsatisfactory after unraveling, and then join it to restore its original appearance. The sand at the interface is generally finer than other places and is not granulated. At the time of identification, if the tight sand is a straight line, pay attention. However, when it comes to rust skin, it is generally difficult to identify.

Fairy scattered flowers: This refers to the selection of a good place, but no loose flower performance on the original stone, choose the location, sprinkle glue on it, and then spread the polished jade powder on the surface, repaired and buried in the soil for dozens of days Just fine.

Opening the window to explore the moon: In the case that the internal situation of the original stone is unknown, in order to find out the internal situation, first open a small hole to find out the inside story. If it is not ideal, then cover the small hole, like this method, it is generally difficult to identify .

Fish head mixed beads: select a good part on the original stone, dig a small groove, then put green glass or green toothbrush, even green toothpaste, and then carefully trimmed to fish. However, most of these things have bubbles in them and the colors are the same. You can identify the true and false by comparing the sand on the edge of the insert with the sand.
