In the face of the variety of jade in the market, how do consumers identify the type of jade? The following small series collects some relevant identification methods to share with everyone. At present, the jadeite is divided into three categories: A, B, and C.
A goods: refers to the use of jade raw materials, directly designed and polished, that is, pure natural. This kind of jade can be worn forever, and the longer it is, the more moist it is, the color is not evil, no impurities, long-term wear does not change color. Wearing A goods has a health-care effect on the human body, expelling disasters and warding off evils and protecting plants. The folks call "A goods" a living treasure. According to the international classification, the standard should be called N jade, that is, natural jade.
B goods: refers to jadeite with more impurities and poor raw materials. After rinsing with strong acid, after removing impurities such as ash, blue, brown and yellow, it retains green and purple, improves its transparency, and has the product of injection molding. Its structure is affected. Serious damage, has lost the role of quality, health, security, this jade will fade for a long time, the gloss is gradually lost, the folks called "dead jade", according to the country's first standard, known as T emerald, that is, optimized jade .
C goods: specifically refers to the artificial dyeing of jade, this dyeing contains heavy metal ions, there will be side effects when applied to the skin, some transparent and flawless good raw materials, dyed, counterfeit A goods jade for sale, there is great deception However, its color is very fast, generally it will be withdrawn within half a year. These jadeites are made of chromate type and green silica gel with warm pressure treatment. The degree of pseudo-reality is high, it is more difficult to identify, and it is necessary to go to the formal inspection. Department testing certification.
Emerald color classification
The common colors of jade are green, white, red, purple, etc. Among them, green is the best variety. If a jade has both green and red and violet, it is also a very rare jade. Since green has the most important commercial value in color, it is mainly introduced to green:
In general, the green jade of business is about "rich, positive, positive, and harmonious." The so-called "concentrate" means green is full and heavy; "positive" means green is pure and contains no variegated color; "positive" means green is bright and bright; "and" means green is even and soft (see Figure 1).
According to the color tone can be divided into the following:
1, emerald, emerald green: green bright, pure, saturated, does not contain any color cast, uniform distribution, fine texture, of which emerald is more saturated than emerald green, is the best in jade.
2, apple green, green seedling green: the color of the green is slightly yellow, almost can not see, the color saturation is slightly lower than the above, is also a rare good in jade.
3, Huangyang Green: green and bright, slightly yellowish, like the early spring of the boxwood leaves.
4, green onion green: green like delicate onion, slightly yellow.
5. Parrot Green: Green is as bright as a parrot's green feathers, slightly transparent or opaque.
6, bean green, bean green: green as bean color, is a common variety in the scorpion, jade is slightly thicker, slightly transparent, including cyan is "bean green".
7, blue water green: transparent to translucent, green with a little blue, fine jade, is also high-grade jade.
8, spinach green: translucent, green with a blue-gray tone, like the green of spinach.
9. Melon green: translucent - opaque, green uneven, and greenish in green.
10, blue and green: blue is obvious, green is dark.
11, dark green: translucent - opaque, rich color, blue and black, pure texture is the best in jade.
12, oil green: better transparency, darker green, blue-gray tone, for the middle and low-end varieties.
13, green: translucent - opaque, with blue, gray-black tone.
14, gray green: poor transparency, green with gray, even distribution.
Divided according to the degree of greenness:
1, brilliant green: transparent - translucent, green pure, uniform, bright, is a valuable variety.
2, Yang Qiao green: green bright and bright, delicate and pure.
3, light green: micro-transparent - translucent, green light and vivid, pure.
4, shallow water green: green light and uniform, good transparency.
B, transparency
It is an important factor in the evaluation of jadeite. It is commonly known as “water head†in the industry. The high transparency is the water head. This kind of jade is crystal clear and translucent, giving people a feeling of water, while the poorly transparent jade is dry and dull, giving people a dry mouth. The feeling is that the head is poor and the water is insufficient. Use the condenser to observe the transparency of the jade, and measure the length of the head with the depth of the light. For example, the depth of 3mm is one water, the depth of 6mm is two water, and the depth of 9mm is three water. The transparency of jade can be roughly divided into transparent, transparent, translucent, micro-transparent and opaque. The more transparent the jade is, the higher its value.
C, texture
Refers to the structure of the jade, some of which refer to the foundation and the ground. Because jadeite is a collection of various minerals, its structure is mostly fibrous structure and granular structure. The fineness and roughness of jade texture are determined by the size of crystal grains. When the crystal grains are large, the texture is rough and semitransparent to It is opaque and has a small crystal grain. The texture is fine and it is transparent to translucent. According to the particle size, the texture can be divided into dense grade, fine grade, medium grade and coarse grade. The dense grade jade can hardly see the particles when enlarged, and the transparency is extremely high.
D, the ground
The part of the jade that is removed from the green is called the ground, also known as the "bottom". The ground reflects the background and structure of the jade, and also reflects the cleanliness and transparency of the jade, which can be divided according to its color, transparency and structure. For the following:
1. Glass bottom: bright and transparent like glass, it is a very high-grade variety in jade (;
2, the bottom of the ice: clear and transparent, crystal clear as ice, giving people a feeling of ice and jade, is also a high-end base in jade;
3, the bottom of the egg white: as transparent as raw egg white, jade is delicate and warm;
4, Furong bottom: jade is finer, more transparent, grainy but can not see the boundaries of the particles;
5, the bottom of the nose: as clear as the nose, the transparency is slightly poor, not bright enough;
6, Qingshui bottom: more transparent, microstrip blue-green;
7, gray bottom: more transparent, slightly grayish;
8, the bottom of the water: translucent, turbid;
9, è—• foundation: translucent, like glutinous powder, slightly pink or purple;
10, fine white bottom: translucent, jade weeping, white background;
11. White sand bottom: translucent, white and sandy;
12. Gray sand bottom: translucent, colored ash and sandy;
13, white flower bottom: micro-transparent, white and thick, with stone flowers;
14, porcelain base: micro-transparent, like white porcelain, grayish white;
15, the bottom of the skull: opaque, such as cooked steamed bread, grayish white;
16, dry white background: opaque, poor gloss;
17, the bottom of the bean: opaque, coarse particles, obvious green;
18. Horse bottom: opaque, like a horse tooth, with a rough texture and a white background;
19, fragrant bottom: opaque, color such as ash, rough texture;
20, lime bottom: opaque, color such as lime;
21, dry green bottom: opaque, coarse stone flower, rough texture;
22, dog bottom: opaque, rough texture, the bottom is not clean, common dark brown or yellowish brown, such as shit.
E, species
The species of jade refers to the general term for the green and transparency of jade, and there is also a saying that the structure and transparency of jadeite. It is an important symbol for judging the quality of jade. Its importance is no less than color. Therefore, there is a saying that "the layman looks at the color and the insider looks at the species." When picking the jade, he is not afraid of no color, and he is afraid that there is no species. It is not that green is not important, but that only green jade gives people a dry feeling and lacks a kind of spirituality. Therefore, there is a kind of jade that not only makes the light-colored jade look warm and crystal, but also makes the green even and full. The emerald water is clear and full of aura.
Traditionally, the species of jadeite is divided into old pits and new pits. The so-called old pits refer to jadeite with pure green, uniform distribution, fine texture and good transparency. The new pit species refers to jade with poor transparency and rough jade. The current classification method can classify jade species into the following categories:
1. Old pit species: It means that the color is dark green, evenly distributed, and the texture is fine. If it is a glass bottom, it can be called the old pit glass species, which is the best in jade;
2, ice species: crystal clear, ice bottom, colorless, so the water head is excellent, is a high-end variety;
3, Hibiscus species: is light green, fine jade, good water head, is a medium-to-high-end variety;
4, gold wire species: green uneven, silky intermittent, good water head, the bottom is also very good;
5, dry green: green thick and pure, but the head is poor, the bottom is dry, the jade is thicker;
6, flower green: green distribution is uneven, veined or spotted, belonging to the middle and low-grade varieties;
7, bean species: jade is rough, opaque, coarser particles, green is called bean green, is a low-grade variety;
8, oil green: jade fine, good transparency, the surface has a oily feel, dark green, color is not pure;
9, horse teeth species: rough texture, poor transparency, white granular. F, ç‘•ç–µ
Emerald enamel refers to some impurity minerals contained in it. Its color and shape have an unharmonious inspection effect on the whole. It is often a spotted black, yellowish brown mineral granule, a silky floc, and a cloud-like white stone flower. On the whole color of jade raw materials or finished products, the presence of these cockroaches will affect the value of jadeite, especially for high-grade jade.
