What are the basic knowledge of jadeite? What are the primers of jadeite knowledge

Color: jadeite pure colorless or white, impurities are emerald green or emerald green, as well as green, apple green, yellow-green, brown, red, orange, purple, violet, gray, black and other colors. Usually there is a saying that the red one is Fei and the green one is Emerald.

Luster and transparency: Jadeite usually has a pearly luster, a vitreous luster, and sometimes a green glitter. The quality is transparent, that is, the water head is good, or the water head is long, and the water is sufficient. The average is translucent to transparent, and the poor quality is slightly transparent or opaque (short or poor head).

1. The word "jade" was first used to refer to two kinds of birds with red and green feathers, called jade birds or "kingfishers", commonly known as "fishing lang", which can still be seen in the rivers and lakes of Quanxi.

2. The use of jadeite to refer to jade is borrowed from the perspective of color: red - jade; Green - Emerald.

3. The world's jadeite producing areas are: Myanmar, Russia, the United States (California), Guatemala, Japan and other places. The best quality jadeite is produced in Myanmar, mainly in the Gorigon Mountains in the Myitkyina region of northern Myanmar, in the area called Hpakant.

4. Silk luster: appears in transparent fibrous mineral aggregates, such as fibrous gypsum, asbestos, etc.

5. Pearl luster: a luster similar to pearl halo appears. Such as mica sheets.

6. Grease luster: appears on the irregular fracture of transparent minerals or mineral aggregates, showing grease brilliance. Such as quartz, garnet, nephrite, Xiuyu.

7. Earth-like luster: appears in powdery and soil-like mineral aggregates, and the surface is dull. Such as turquoise, lapis lazuli.

The introduction to jadeite knowledge is as follows:

1. In the jadeite world, professional terms such as primary three, middle four, and big five actually represent a ** range and do not specifically refer to a certain precise number.

2. The small ** is between 1-3, the medium is between 4-6, and the large is between 7-9, and the number followed by the large, medium and small is the number that represents the **digits, for example: the third is 100-399, the fourth is 4000-6999, and the fifth is 70000-99999 A piece of jade is 800 yuan, so it can be said that this price is the third year.

3. If you look closely at the jadeite, you can see that there is a little or a very thin dark green on the jadeite, and the darker green gradually fades and slowly transitions to a lighter green, which is the color root.

4. Fly wings are only one of the manifestations of jadeite jadeite, which is mainly the intuitive expression of the particle size and mutual combination relationship of jadeite, the main component mineral of jadeite, under the observation of the naked eye, and in layman's terms, it is the reflection of the cleavage surface of jadeite minerals that can be seen on the surface of jadeite.

5. The water head of jadeite is a word we often hear, in fact, the water head refers to the transparency of jadeite. We usually say that the head is long or short, and the head is good or bad.

You can read more books related to jadeite, which is also the most important way to learn jadeite knowledge, not only to eliminate external interference, but also to accumulate jadeite-related experience while learning jadeite knowledge, killing two birds with one stone.

Jadeite is a type of jade, and the correct definition of jadeite is a fibrous aggregate composed of pyroxene minerals dominated by jadeite minerals.

The constituent minerals of jadeite are mainly jadeite in monoclinic pyroxene clusters, or other pyroxene minerals (such as chrome jadeite, omphacite and so on) containing high jadeite molecules (Naalsi2O6), and jadeite that reaches gem quality is called jadeite.

All the high-quality jadeite on the market is basically produced in Myanmar, but in fact, there are many sources of jadeite, not only Myanmar. However, in recent years, the jadeite produced in Guatemala is also similar to blue water jadeite, which has gradually been recognized by the market, but Guatemalan jadeite is basically gray and blue in background color, far less than the color and water of Myanmar jadeite.

The "jadeite" of jadeite refers to the reflection of the cleavage surface of jadeite minerals that can be reached directly on the surface of jadeite, commonly known as jadeite"Fly wings"。

Generally speaking, it is easier to see "fly wings" in jadeite rough wool and unpolished wool. Emerald's"Emerald sex"It is an important symbol to distinguish the authenticity of jadeite.

Jadeite Basics:

1. Jadeite, also known as jadeite jadeites, jadeite, Burmese jade, is a kind of jade. The correct definition of jadeite is a fibrous aggregate of pyroxene minerals dominated by jadeite minerals. But jadeite is not equal to jadeite.

2. Jadeite is a jade-grade stone polycrystalline aggregate formed under geological action, mainly composed of jadeite or jadeite and sodium (sodium chromium pyroxene) and sodium calcareous pyroxene (omphacite), which can contain hornblende, feldspar, chromite, limonite, etc.

3. "Bashan jade" rough stone is a kind of "brick material" with coarse crystals, loose structure, dry water and poor bottom, but its color is relatively rich, with light purple, light green, green or blue gray and other colors, it is a special jadeite with low grade and containing minerals such as amphibole and albite.

4. The world's jadeite producing countries include China, Guatemala, Japan, the United States, Kazakhstan, Mexico and Colombia. The jadeite in these countries is characterized by very few gem-quality jadeite, and most of them are carved grade craft raw materials. Cele County, Hotan Prefecture, Xinjiang, China, also produces small amounts of jadeite ore.

5. There are more than a dozen varieties of common varieties such as old pit jadeite, ice jadeite, and water jadeite.

The basic knowledge of jadeite is as follows:

1. There are many types of jadeite, and the most common categories can be intuitively divided by color, that is, colorless jadeite, white jadeite, green jadeite, yellow and red jadeite, purple jadeite, blue jadeite, black jadeite and so on. The most intuitive is to distinguish by color, and secondly, there will be a mixture of different colors of jadeite, resulting in a variety of special cases with different appearances.

2. The more transparent the jadeite, the more precious it is; The brighter the color of jadeite, the more precious it represents.

3. The fewer the internal and overall inconsistencies of the jadeite, the more precious it is.

4. The fuller the shape of the jadeite and the less carved it is, the more precious it represents.

5. In the same price of jadeite with full color and green, you must choose a better water, and the value retention rate will be higher.

6. The species of jadeite: the species refers to the structure of jadeite, jadeite is a tightly structured aggregate composed of countless crystal particles, the smaller the crystal particles, the closer the species is to the glass species, and the larger the crystals, the closer to the bean species. Under the premise of fine structure, jadeite is classified according to species, which can be divided into glass species, ice species, glutinous species, bean species jadeite, and then further subdivided, and there are high ice species, glutinous ice species, waxy species, etc.

7. Jadeite water: Water refers to the "water head" of jadeite, which is the transparency of jadeite. The length of jadeite water can be divided into transparent, translucent, and opaque. Because the "species" of jadeite often directly affects the "water" of jadeite.

8. Old and tender jadeite: The old and tender (or new) of jadeite refers to the density of the crystals in the jadeite. The jadeite is composed of a lot of crystal particles, the jadeite water is based on the jadeite crystal structure to reach a certain density to talk about, so its crystal particles are very loose jadeite we usually call the jadeite without water, its surface is dry, the density is very small, a drop of water quickly seeped into the gap of the jadeite sparse.

The tighter the connection between the jadeite crystals, the higher its hardness, the sparks are sparkling when cut, and it is very difficult to cut the knife. The tender jadeite crystals are not tightly connected and relatively soft.

9. The color root of jadeite: If you look closely at the jadeite, you can see that there is a little or a very thin dark green on the jadeite, and the darker green gradually fades and slowly transitions to a lighter green, which is the color root.

10. The jadeite nature of jadeite: The jadeite nature of jadeite is also known as fly wings, which is a unique feature of jadeite. Fly wings are only one of the manifestations of jadeite jadeite, it is mainly the jadeite in the main component of the mineral jadeite particle size and mutual combination relationship under the naked eye observation of the intuitive performance, in layman's terms, it is the jadeite mineral cleavage surface that can be seen on the surface of jadeite, the more obvious the fly wings, the more obvious the jadeite.

Combined with the current jade market, knowing some jadeite knowledge and mastering some professional terms is very helpful for us when buying jadeite jewelry. The following is a summary of some basic knowledge of jadeite, I hope it can help you. Let's take a look at the relevant introduction.

Composition of jadeite

Jadeite is mainly composed of jadeite minerals or other albiteous pyroxene containing high jadeite molecules, also known as albite pyroxene, but also accompanied by a small amount of other pyroxene, amphibole, albite and other minerals. Ingredients: Naal (Si2O6).

In English: jadeiteHardness, specific gravity, refractive index.

Common varieties of jadeite texture are:

1. Glass ground: glass ground refers to the structure of jadeite is very delicate, transparent, translucent, like glass, the measurement of glass ground is to see the transparency of jadeite with the naked eye, generally expressed with water head, a point of water is 3mm jadeite is translucent; The second water division is 6mm thick jadeite, which is translucent.

2. Ice ground: It refers to the delicate structure of jadeite, which is translucent, just like ice.

3. Egg green ground: It is a relatively turbid glass ground variety.

4. Oil green: refers to the main base color of jadeite, with delicate texture and dark color, including oil blue, egg blue, blue and blue, etc.

5. Dry ground: rough texture and opaque. Some people describe it like this, like a goldfish in a fish tank, the fish is dead when the water is dry, if the jade has no head, there is a green and it is also dead.

The color of jadeite has

1. Bright green: green is pure, positive and strong, but without black tones.

2. Blue-green: green with a blue hue, which is called green and micro-blue from a gemological point of view. It is precisely because of its green and blue hue that it looks full of calm mystery and gives people a deep feeling.

3. Emerald green: Burning green and fresh, if born in the glass skin imitation ground, like green water, the color is brighter and lighter, which is the representative of standard green.

4. Yang green: green and fresh yang, with a slight yellow tone, and because of its yellow taste, the green has a bright sense of life.

5. Light green: the green is light, not fresh enough.

6. Turbidity green: The color is darker than light green, but slightly turbid.

7. Dark green: Although the color is strong but dark, it is not much worse than the fresh sun, but it still does not lose the green tone.

8. Black and green: green is concentrated to black tones.

Jadeite work (4 levels in total).

In this grading standard, "work" refers to the shape, workmanship, and weight of a finished jadeite product, it should be pointed out that due to the differences in designer, technology, cultural connotation, production age, volume, etc., each piece of work has its own characteristics, and detailed grading can not be done.
