Jadeite, also known as emerald jade, emerald jade, jadeite, Burmese jade, is a kind of jade, the color is emerald green (called emerald) or red (called emerald). It is a jade-grade polycrystalline aggregate mainly composed of jadeite, omphacite and sodium chromium pyroxene formed during geological processes.

1. Common varieties

1. Laokeng jade is commonly known as "Laoken glass" in commercial circles. It usually has glass luster, its texture is fine and pure without blemishes, and its color is pure, bright, rich and uniform emerald green. Therefore, it is extremely difficult to see the "greenness" with the naked eye; the jadeite of the old pit species is translucent-transparent under the irradiation of light, which is the top or best grade of jadeite.

2. The texture of the ice jade is similar to that of the old pit jade. It is colorless or less colored. The feature of the ice jade is that the surface of the ice jade is very shiny, translucent to transparent, and clear like ice, giving people a clear and jade-like appearance. Feel. If the ice jade has a variegated or intermittent vein-like blue color, it is called "blue flower ice", which is a common variety of ice jade. Ice jade is often used to make bracelets or pendants. There is no obvious difference between the value of colorless ice jadeite and "blue flower ice" jadeite, and its actual price mainly depends on people's preferences. The ice species is mid-upper or mid-level jadeite.

3. The jade structure of water jadeite is slightly thicker than that of Laokeng glass jadeite, and its luster and transparency are also slightly lower than that of Laokeng glass jadeite, but similar or equivalent to that of ice jadeite. Its characteristic is that it is as transparent as water but has a soft luster. Looking closely at its internal structure, a little "ripple", or a small amount of dark cracks and stone patterns can be seen, and occasionally there are very few impurities and cotton willow. Some experts say that water jade is light or colorless, and the quality is slightly worse. It is a variety of middle and upper grades and occasional upper grades in jadeite.

4. Violet Jade This is a kind of purple jadeite whose color resembles violet flowers. In the jewelry industry, violet is also called "chun" or "spring color". Emeralds with "spring color" can be classified into high, medium and low grades. It doesn't mean that as long as it is violet, it must be valuable and must be top grade. It must also be comprehensively evaluated based on quality indicators such as texture, transparency, and craftsmanship. The purple on jade is generally not deep. According to the different shades of purple, the emerald world divides the purple in jade into pink purple, eggplant purple and blue purple. Pink purple is usually finer in texture and better in transparency, followed by eggplant purple and blue purple again. Of.

5. Emerald with white background Green jadeite with white background is characterized by its background being as white as snow, and the green color looks bright and distinct on the white background. This type of jade is easy to identify: the green color is distributed in spots on the white background, the transparency is poor, and it is opaque or slightly transparent; the jade pieces have a fiber and fine-grain mosaic structure, but the fine-grain structure is the main one; It must be magnified 30 to 40 times), and the surface is often perforated or uneven. Most of this variety is middle-grade jadeite, and a few have clear green and white, bright green and good color shape, and the color and base are very coordinated, which can reach the middle and high-end grade.

6. The emerald green emerald green color is distributed in veins, which is extremely irregular; the texture is thick and thin, translucent. Its base color is light green or other colors. Such as light gray or bean green, its structure is mainly fiber and fine-grain-medium grain structure. The characteristic of cyan jadeite is uneven green color. Some are denser, some are more sparse, and the color can be deep or light. There is also a structure in the cyan jadeite that is only granular and lacks a sense of water. Because of its rough structure, the transparency is often poor. Huaqing is a middle-grade or middle-low grade jadeite.

7. Red jadeite is bright red or orange-red jadeite, which is easy to see in the market. The color of the red jadeite is formed after the formation of jadeite crystals, which is caused by the dissemination of hematite. It is characterized by bright red or deep red. A good red jadeite has a good color, glass luster, and its transparency is translucent. Red jadeite products are usually mid-range or low-end commodities, but there are also high-end red jadeites: bright in color and fine in texture. , Very beautiful, loved by people, emerald with auspicious color.

8. The color of yellow-brown jade is from yellow to brown-yellow or brown-yellow, and the degree of transparency is low. Jade products in this series of colors can be seen everywhere in the market. Their color is also formed after the jadeite crystals are formed, and they are often distributed on the red layer, which is caused by limonite dissemination. In the market, the value of red jadeite is higher than that of yellow jadeite, which is higher than that of brown-yellow jadeite, and the price of brown-yellow jadeite is second. However, there are also cases where the price is different from the usual ones due to people's love and unique characteristics of accessories.

9. Bean seed jade is called bean seed for short, and bean seed jade is a very common species in the jadeite family.

10. Hibiscus jadeite is called hibiscus for short. This kind of jadeite is generally light green without yellow tint. The green is relatively clear and pure, and sometimes its base is slightly pink.

11. Although the texture of horse teeth jade is relatively fine, it is opaque, and the surface luster is like porcelain.

12. The texture of lotus root starch jadeite is as delicate as that of lotus root powder, and its color is light pink and purple (light spring color). It is a good raw material for handicrafts.

13. The characteristics of the wide film are that the green is dark or black under natural light, the texture is thicker and the water head is drier.

14. Emerald jadeite of Cuisi type This is a kind of jadeite with excellent texture and color, and it is a medium-to-high-grade jade in the market.

15. The golden silk species contains yellow and orange-yellow strips in the shallow bottom, and the filaments are arranged in parallel and the directional structure is clearly developed. Except for the color, other characteristics are similar to those of the green silk species. same. But usually the price of gold silk jadeite is lower than that of green silk jadeite.

16. Oil-green jade is referred to as oil-green or oil-immersed. Its transparency and luster look oily. It is a medium-to-low-grade jade that can be seen everywhere in the market. It is often used to make pendants, bracelets, and ring faces. The green color of oil green species is obviously impure, containing gray and blue components, so it is dull and not bright enough.

17. Bashan jade "Bashan jade" rough stone is a kind of "brick material" with coarse crystal material, loose structure, dry water and poor bottom, but its color is relatively rich, such as lavender, light green, green or blue gray. A low-grade special jadeite containing minerals such as amphibole and albite.

18. Dry white jadeite is white or light off-white jadeite with rough texture and poor transparency. The evaluation of jadeite experts is: the seed is thick, the water is dry, and it is not moist. This variety is colorless or light in color, and the boundaries between crystal grains can be seen with the naked eye, so the appearance structure is rough, and its use and ornamental value are low. It is a low-grade jadeite variety.

19. Mo Cui is black and shiny at first glance, and it is easy to be mistaken for Mo Yu in Dushan Jade or other black gemstones. However, when observed under transmitted light, it is translucent and transparent in black. Green, especially the flakes of emerald, is pleasing to the eye in transmitted light. The Burmese use "lover's shadow" to describe black jadeite, and the Chinese name it "Mo Cui".

20. The iron dragon is full of green jade pieces. Its mineral deposits were discovered in 1990 and openly mined in 1994 and were almost exhausted in 2000, so there are few good iron dragons in the market.

2. Evaluation of Jade Terminology

There are terms such as "earth", "good water" and "good emerald" to evaluate jadeite. "Earth" refers to other colors in jadeite, and less jadeite is mostly top-grade; "good water" refers to the texture of jadeite is tender and lubricated, transparent and clear, crystal dignified, bright and pleasing, also called "pretty", otherwise it is called "water difference". "; "Cui De Hao" should be combined with the four characters "Nong, Yang, Zheng, and", "Nong" means thick but not light, like holly after rain, "Yang" means bright and bright, "Zheng" means no Color and evil color are mixed, "harmony" means that the emerald green is uniform without depth, otherwise it is called "light, yin, evil, flower".

3. Emerald land

The glass ground is completely transparent and has a vitreous luster. Emeralds are not as transparent as gemstones. A good glass bracelet looks as transparent as crystal without impurities.

Ice and ice are second only to glass, and everything is as transparent as ice, that is, if there is a layer of mist in the transparency, it is like clear water frozen and stagnant.

The water is as transparent as water, with a glassy luster. Similar to glass, with a small amount of impurities.

Egg green texture is like egg green, glassy luster. Translucent, but relatively pure, without impurities.

The texture of the snot is like blue snot, with glassy luster. Translucent, but relatively pure, with a small amount of impurities.

Qingshui is transparent in geology, but the pan-turquoise is a turquoise waterland variety, and it is not as good as the waterland variety due to color interference. The gray water texture is translucent, but grayish. Because of the gray color, the quality is worse than that of Qingshuidi.

The texture of purple water is translucent, but with a purple tinge. Unlike violets, which emphasize transparency, they are actually translucent violets.

The muddy water is translucent, like muddy water. Water with poor transparency.

Fine white translucent, fine white color. If the luster is good, it is also a good raw material for jade carving.

Baishadi is translucent, sandy and white. Not fine and fine white ground.

The gray sand is translucent, sandy and gray. Not fine gray white sand.

The bean green ground is translucent, the bean green ground. It is actually a bean-green translucent variety.

The purple flower ground is translucent with uneven purple flowers. For violets of uneven color.

4. Grading

① Special grade: bright green (emerald green), apple green, glass floor (translucent, fine texture), uniform and bright, no impurities, no cracks.

②Commercial grade: green, oily ground, slightly transparent, interspersed with translucent emerald veins and spotted emerald.

③Ordinary grade: lotus root powder, bean green, light green, white and delicate, slightly transparent. Opaque jadeite is generally only made of jade jewelry.

V. Selection and Valuation Principles

The top-quality jadeite is called jadeite. Color, transparency, uniformity, shape, and knocking are the methods for ordinary people to appreciate or evaluate jade, and jade is divided into: glass type, dark old pit, old pit, gold thread, oil clear , bean green, anthocyanin, melon green and so on. Among them, the glass jadeite is the top grade, and the "ice jadeite" with extremely high "moisture" and good transparency is also called "ice jadeite", which can be said to be a treasure among "glass jadeite". Most consumers who buy jade bracelets may have such experience, that is, merchants will knock on jade bracelets in front of you, and listen to see if the sound is clear and free of turbidity, and it is better to be clear and melodious with an echo. This is done to prove that the crystallization of jade is compact and has no cracks.

1. Emerald green: the more delicate the green, the more valuable it is.

2. Transparency: Jadeite’s internal crystalline structure is better, and its transparency is also high. What we call “glass type” is this kind of jadeite with high transparency. For example, because the jade itself is rich in chromium, it forms ice type jadeite. Expensive and hard to find.

3. Uniform color: In addition to the bright green color and high transparency, the top grade must also be uniform in color tone.

4. Defects: Pay attention to whether there are cracks, spots, etc. These defects will affect the quality of jadeite.

5. Shape: Most of the jadeite ring faces are oval egg-shaped. As for other shapes, there are many kinds. The quality and beauty of the shape also have an impact on the price of jade.

6. Carving: The quality of the carving and the symbolic meaning of the decoration of the carving have an impact on the price.

7. Size and thickness: Of course, jade of the same quality is bigger and thicker at a higher price.

8. Gloss: In addition to the above conditions, the gloss should be bright and not dark.

6. Others

The "species" of jadeite refers to the structure and structure of jadeite. It is an important symbol of jadeite quality. The new "species" (also known as Xinkeng Xinchang, etc.) of jadeite has loose texture, coarser and uneven particle size, more impurity mineral content, more developed cracks and micro-cracks, but not necessarily poor transparency, and uniform specific gravity and hardness. There is a decline. Old "species" (also known as Laokeng Laochang, etc.) jadeite has a fine and dense structure, fine and uniform particle size, and no small cracks. It has the highest hardness and specific gravity, and is a better quality jadeite. But not necessarily transparency. The new and old kinds of jadeite are between the new kind and the old kind of jadeite. They are the jadeites that have been accumulated on the hillside in situ, and have not been naturally transported or transported over a short distance. The new species of jadeite is the raw material for making jadeite B goods.

The meaning of "earth" of jadeite is the degree of coordination between the cleanliness of the green part of the jadeite and the part other than green, water (transparency) and color, and the relationship between "species", "water" and "color". The folks call "land" as "di Zhang" or "bottom barrier". The emerald and the outer part of the emerald must be coordinated. For example, if the emerald is good, the emerald and the outer part of the emerald must be watered. The "water" and "seed" of emerald should be coordinated. For example, the "seed" has a good old color, good water, and few impurities and dirty colors. They set off each other and strongly reflect the beauty, luster and value of emerald. The structure of the "earth" should be delicate, the color tone should be uniform, the impurities should be less dirty, and there should be a certain degree of transparency. Good "ground" is called glass ground, waxy ground, and egg white ground. The bad "land" is called lime land, **** land, etc. Jadeite with bad water is called "bottom dry".

The "water" of jade refers to its transparency, also known as water head. The emerald water is related to the structure of the emerald, that is to say, it is related to the "species". It is also related to the content of impurities. Emerald water with old "kinds", less impurities, uniform particle size and high purity is good.
