First, the variety of jadeite:
1. Black ice ink painting
Black ice is a kind of gray-black to dark-black jadeite, more than 98% of which is jadeite, belonging to a single mineral rock with dense and delicate structure. Black is produced during the formation of jadeite under the surface, which is often formed by the infiltration of organic carbon. In the industry, because of its black texture, it looks like an ink landscape painting, and the old experts also call it "the ink painting of jadeite".
2. Cui Mo
At first glance, it is shiny black, which can easily be mistaken for jet or other black gems in dushan jade. It is dark and oily under natural light, translucent under transmitted light, and green in black, especially thin ink, which has gratifying color under transmitted light. Burmese people use the "lover's shadow" to describe the black jade, and China people named it "Cui Mo".
3. Ice seeds
The texture is similar to that of the old cellar species, colorless or less colored. The characteristics of ice species are that the outer surface has a good luster, translucent to transparent, clear as ice, giving people a feeling of ice and jade. If there is a flocculent or intermittent blue color in ice jadeite, it is called "blue flower ice", which is a common variety in ice jadeite. Kethleen is often used to make bracelets or pendants.
There is no obvious difference in value between colorless ice jadeite and "Lan Bing" jadeite, and its actual price mainly depends on people's preferences. The so-called ice seed refers to a variety with extremely transparent and moist texture, which is similar to Jinshui Bodhi in colored gems, but the difference is that there is no so-called cotton in high-quality chalcedony, and the texture is more shiny.
Step 4 grow jadeite in water
The jade structure of water jadeite is slightly thicker than that of old pit glass, and its luster and transparency are slightly lower than that of old pit glass, but it is similar or equivalent to ice. Its characteristic refers to the transparency of jadeite. The higher the transparency, the better the water head. Species refers to the internal structure. The denser the internal structure, the older the species. On the contrary, the rougher the internal structure, the more tender the variety is, transparent as water, but soft in luster. Microscopically, there are several "ripples", or several dark cracks and stone lines, and occasionally there are very few impurities and cotton willows. Some experts say that water jadeite is a kind of old pit jadeite with light color or colorless and slightly poor quality, and it is an upper-middle grade jadeite with occasional upper grade.
5. Bashanyu
Bashan jadeite is a kind of "brick material", with coarse crystal material, loose structure, dry water and poor bottom material, but rich in color, such as lavender, light green, green or blue gray. It is a special jadeite with low grade and containing amphibole, albite and other minerals.
6. Hongfei
Bright red or orange emeralds are easy to see in the market. The color of Hong Fei was formed after the formation of jadeite crystals, which was caused by hematite impregnation. It is characterized by bright red or crimson, good red, glassy luster and translucent transparency. Red Philip products are often mid-range or low-grade goods. But there are also high-grade Hongfei: jade with bright color, delicate texture and very beautiful, which is loved by people and has auspicious color.
7. Wide film
It is characterized by dark green or dark green under natural light, rough texture and dry head.
8. Huang Zongfei
The jadeite whose color ranges from yellow to brownish yellow or brownish yellow has low transparency, and this series of jadeite products can be seen everywhere in the market. Their colors are also formed after the formation of jadeite crystals, often distributed on the red layer, which is caused by limonite impregnation.
In the market, the value of Hong Fei is higher than that of yellow jadeite, while that of Huangfei is higher than that of brown jadeite, followed by brown jadeite. But there are also cases where the price is different from the routine because of people's love and unique jewelry. There are two kinds of topaz, yellow to brown, which are generally called golden autumn species, like crops in autumn harvest season; Brown to brown is also called sauce glaze, the color is like porcelain sauce glaze, also called old.
9. Gan Qing species
The jadeite in Gan Qing is rich green and pleasing to the eye, pure and flawless, similar to the jadeite with dark color, and sometimes dark in color. No matter whether the color is dark or light, Gan Qing, which is dominated by sodalite, has a relatively low hardness, so the color is dull and weak, which is one of the obvious differences between it and ordinary jadeite.
The outstanding shortcomings of jadeite planted in Gan Qing are poor transparency, weak sunlight irradiation ability, rough texture, dry bottom and rough sound of striking the original stone. Chromite inclusions with metallic luster are common on the surface of Gan Qing.
10. Tie Longsheng
Jade flakes full of green. Its mineral resources were discovered in 1990, exploited in public in 1994, and almost exhausted in 2000, especially in the market. Tielongsheng is a kind of medium-grade jadeite, which is bright green, but with different shades, poor transparency and loose structure. Columnar crystals are arranged in a certain direction and can often be seen in the market. "Tielongsheng" is pronounced in white Burmese, and the Burmese word "Tielongsheng" means full green.
1 1. Huaqing Emerald
The color is green, veined and extremely irregular; The texture is thick, thin and translucent. Its background color is light green or other colors, such as light gray or bean blue, and its structure is mainly fiber and fine-grained to medium-grained structure. Huaqing jadeite is characterized by uneven green, some dense, some sparse, and some deep and light colors. Another structure of Huaqing jadeite is that it is only granular and lacks a sense of water. Because of its rough structure, its transparency is often poor. Huaqing belongs to middle and low grade jadeite.
12. Youqing Jade
Oil-green jadeite is called oil-green jadeite or oil-soaked jadeite for short, and its permeability and luster look shiny. It is a low-grade jadeite that can be seen everywhere in the market. It is often used to make pendants, bracelets and rings. The green color of oil green species is obviously impure, containing gray and blue components, so it is dim and not bright enough.
13. Bean seed jade
Bean seed jadeite, referred to as bean seed for short, is a very common variety in the jadeite family.
14. planting jadeite in the old pit
Commonly known as the "old pit glass species" in business circles, it usually has glass luster, delicate and flawless texture, pure, bright and rich color, and even emerald green; The jadeite jade in the old pit is very fine, and it is extremely difficult to see the "emerald" with the naked eye. Laokeng jadeite is translucent and transparent under the irradiation of light, which is the top grade or the best of jadeite.
15. Violet jade
This is a kind of purple jade, the color is like violet flower, and violet is also called "Toona sinensis" or "spring" in jewelry industry. Emeralds in "spring" are divided into high, medium and low grades. Violets are not only valuable, but also top grade. It must be comprehensively evaluated by quality indicators such as texture, transparency and process production level.
The purple on jadeite is generally not deep. According to the different shades of purple, the jadeite industry divides the purple in jadeite into pink purple, eggplant purple and blue purple. Pink purple is usually fine in texture and good in transparency, followed by eggplant purple and blue purple again.
16. Jade with white background
Green on a white background is characterized by white as snow, and green is very bright on a white background. This variety of jadeite is easy to identify: there are green spots on the white background, and the transparency is poor, opaque or slightly transparent; Jade pieces have fiber and fine grain mosaic structure, but the fine grain structure is the main structure; Observed under a microscope (it must be magnified 30 ~ 40 times), its surface is often perforated or uneven.
Most of this variety is mid-range jadeite, and a few are blue and white, with bright and bright color, which is in harmony with the background and can reach middle and high grade.
17. Frozen waxy jadeite
Waxy species generally refers to a kind of jadeite species with good transparency and good water head, and waxy species can reach the level of ice species. In order to distinguish common waxy varieties, this is also called ice seed melting.

22. Golden silk long emerald
There are yellow and orange jadeites at the shallow bottom, which are banded and arranged in parallel filaments, and the directional structure is obviously developed. Except the color is different from that of Cui Si species, other characteristics are the same as those of Cui Si species, but the price of gold-rimmed jadeite is usually lower than that of Cui Si species.
23. Dry white jade
Dry white jade is white or grayish white jade with rough texture and poor transparency. Jade experts rated it as rough, dry and moist. This variety is colorless or light-colored, and the boundaries between grains can be seen by naked eyes, so its external structure is rough and its use and ornamental value is low, so it belongs to a low-grade jade variety.
