Who knows how to distinguish between jade and jadeite What is the difference between the two

The fine jade is moisturizing, transparent, greasy, and warm when pinched in the hand. The main way to distinguish the true from the fake is with the help of a magnifying glass or microscope, which can see that the inside of the jade is a fiber interwoven structure with fine particle size; Whereas artificial glass has no structure, bubbles can be seen. You can also carve with a knife in an inconspicuous place of jade, and what can be carved must be fake jade, and what cannot be carved is real jade.

As the saying goes, "** priceless jade is priceless". Because the high-grade Hetian jade is becoming more and more scarce, each kilogram can reach tens of thousands to hundreds of thousands of yuan, and the general Qinghai white jade, Russian white jade and other kilograms are only thousands of yuan, so some people mix this with Hetian jade. The minerals of these jades are basically the same as those of Hetian jade, but the surface color is darker and not softer, and it will be darker over time.

Appreciating jadeite should pay attention to color and germplasm, which can be subdivided into color, transparency, clarity, cut and cracks, and generally start with its color. Color Color is the most important factor affecting the value of jadeite, and the color of jadeite can be evaluated from the following four domains: To be pure:

Pure refers to the ratio of the main color and the secondary color of jadeite, taking green jadeite as an example, pure green is the best, green with yellow or blue is inferior, and gray is the worst. To be the right shade: when it comes to the depth of the color, of course, the thicker the better, but too strong the color will cause the opposite effect and reduce the quality of the jadeite.

Be distinct: the brighter and brighter the color of jadeite, the more attractive it is, and the more proportion of gray or black it contains, the darker the color To be even: the more evenly distributed the color, the better, and the higher the value.

Transparency The transparency of jadeite affects the refraction of light, which affects the overall beauty. When the light enters the transparent and delicate jadeite, it will reflect a beautiful light, making people feel the crystal transparency of the jadeite, which greatly increases its beauty. On the contrary, if the light encounters a jadeite with low transparency and rough texture, it will reflect the dull light, which will greatly reduce the attraction of the jadeite.

Clarity Clarity refers to the imperfections contained in jadeite, mainly white and black, which are caused by the inclusion of other minerals in jadeite, and black blemishes are relatively more eye-catching than white. The fewer impurities in jadeite, the better. Cut The processing of jadeite products is divided into two categories: bare body and carving.

In addition to the absence of cracks, the proportion of the cut, the thickness of the product and whether it is symmetrical are also very important, which can affect the appearance of the jadeite finished product. For example, a well-cut egg should not be too thick or too thin, and the divination should be in the center and the proportions should be moderate. The evaluation of flowers is mainly based on their beauty and the fineness of the carving, and usually cracked jadeite will be treated in a carved way to cover up its imperfections.

Cracks Cracks can greatly reduce the value of jadeite. If there is a crack in the jadeite ornament, the slightest collision may crack along the crack. Therefore, extra care should be taken when buying jadeite ornaments, generally speaking, it is easy to detect the presence of cracks by irradiating them with a flashlight.

Remember.

There are only 2 classifications of jade: jadeite nephrite, jadeite is what we call jadeite, nephrite is Kunlun jade (that is, Hetian Qinghai jade) The constituent minerals of jadeite are mainly jadeite in monoclinic pyroxene clusters, or other pyroxene minerals (such as chromium jadeite, omphacite and so on) containing high jadeite molecules (Naalsi2O6), then the composition of nephrite is tremolite. 1. Hardness, the Mohs hardness of Hetian jade is, the hardness of jadeite is about 6, the hardness of glass is about 6, and the hardness of ordinary knives is about about, so whether your jade can scratch the glass shows its Mohs hardness. 2. Density, the density of good jade is very large, the internal texture is tight, and there will be absolutely no bubbles.

3. The specific gravity of jade is much larger than that of glass, so there is a feeling of immersion in the hand of jade, and the better the texture, the greater the proportion of jade. 4. Structure, there will generally be a short cloud floc structure in the jade, and the short cloud floc structure should be seen by side light, not from the back, and the back light can only see impurities, and the structure cannot be seen. For Hetian seeds, the finer the cloud floc, the better, the seed material with high whiteness will generally be slightly larger, and the whiteness is high and the structure is very dense, ** is very expensive.

5. Experience is the most important, if you like jade, you should see more and buy less, if you can find someone who understands jade, it is best to communicate with each other, so that it is very fast to learn. Now there are a lot of fakes, science and technology are also developed, and the more fake ones are made, the more they look like the real thing, so you have to look at the 4 grades of jadeite (a, b, c, d,) A grade is the best and so on. Jadeite is a kind of jade, belonging to jadeite, the constituent minerals of jadeite are mainly jadeite in monoclinic pyroxene clusters, or other pyroxene minerals containing jadeite molecules (Naalsi2O6) are high (such as chromium jadeite, omphacite and so on), in a word, jadeite is definitely jade.

But only A-grade jadeite is collectible.

Identifying the quality of jade or jadeite should be judged by the following criteria:

One is to look at the color, there are many types of colors, among which green is respected, purple is expensive, red and yellow are rare, these colors can greatly improve the value of jade or jadeite. However, for example, the same green, there are different kinds, and there are also great differences;

The second is to look at the quality of jade, the value of good jade quality must be large, the value of poor jade quality is small, and those transparent, delicate, oily, and sunny jade or jadeite are generally of high value;

Three look at the carving (not suitable for jade or jadeite rough stones), the appearance of the same carving, the value of ordinary jade master carving and jade carving master carved is very different.

In general, it is necessary to "look at three times."

1. Look at the color: there are many colors of jadeite, the most common are white, green, red, yellow, purple, gray, blue-brown, black and other colors, among which green is the rarest, so it is the most precious, but also the value, green to bright and tender green emerald green for the best, to thick, yang, positive, uniform for the top grade, pure violet, beautiful red value is also very high, red, green, white three colors (Fu, Lu, Shou) is more good.

2. Look at the texture: that is, the background color of jadeite is called "ground" and "species", the better the transparency, the higher the value, according to the different performance of the texture structure of the "species" or "ground" is also different, the common glass species, ice species, flower green species, oil clear species, bean green species, dry green species and so on.

3. Look at the carving work: refers to the carving process of jadeite, the value of a piece of jadeite and its carving process is fine, the ingenuity of the meaning has a very important relationship, "three materials, seven division of labor" pure manual carving and jadeite color different characteristics make each finished product unique. The original stone is buried deep in the bottom, after the changes of the earth's crust, if it can be combined into one, it is a beautiful jade that is difficult to find in the world, and it is invaluable.

1. A drop of water, if it solidifies for a long time, it is a good jade.

2. Good jade generally feels cold and lubricated to the touch.

3. Good jade will have an astringent feeling when placed on the tip of the tongue.

Hope it helps.

The simplest point. Look at nature.

What is beautiful is what is good. Anyone with an aesthetic sense can see the good and the bad. False exceptions, of course.

The identification of the quality of jadeite is very intuitive, and the more beautiful the better, under the premise of ensuring natural jadeite!

The higher the transparency, the better the clarity, the more exquisite the carving, the more regular the shape, the brighter the color, and the higher the value!

Look at the poor planting water of the material, the naked eye looks at the cotton crystal structure is obvious, the good meat is fine, the water is good, and on the basis of the good planting water, plus the color, the jade is respected by green.

The quality of jadeite can be identified by the water, color, texture, cracks, stone grain, etc. of jadeite, for example, the texture of jadeite is delicate, and the value of jadeite with good water head is relatively high. The color of jadeite is rich and colorful, pay attention to "thick, yang, positive, pretty, and", green jadeite has the highest value, but not all green jadeite is more valuable than other colors of jadeite.

The quality of jadeite is determined by three aspects, water, species, and color.

1. Weight. Because the density of jadeite itself will be relatively large, we can put the jadeite in the hand up and down a few times, and feel that there will be a heavy downward pressure feeling, and there may be a real jadeite with this feeling. When the fake jadeite is in the hand, it will be a light feeling, and there is no downward pressure feeling.

This is a good way to identify medium-sized jadeite.

2. Color root. Natural jadeite, especially green jadeite, has colored roots. The color root is where the green is very strong, and then the green will spread around the color root.

Under the transmission of strong light, the green color will fade or disappear in some places, but the color root will still appear green. Treated jadeite or other kinds of jade have no color roots.

3. Color. The color of natural jadeite is natural, unevenly distributed, and generally non-fluorescent; Artificially treated jadeite can see a stripe of reticulation under reflected light, and epoxy-filled jadeite fluoresces under ultraviolet light.

Some dyed jadeite will be blue and gray in color, and it will not look natural. The surface of real jadeite is very smooth to the touch, and it will look very shiny in the sun, and the internal pattern is also very delicate and has a cool feeling. Fake jadeite will feel rough to the touch, the surface is not very smooth, the color will appear dull, and there may be bubbles inside.

<>1. The difference in appearance: gloss is the biggest difference between jade and jadeite, and people who know how to distinguish nephrite and jadeite through light. Nephrite's luster is warm, while jadeite has a vitreous sheen and a chill.

2. The texture of jade is tough and delicate, and the color is uniform. Nephrite has crystalline grains that are white sugar, which is relatively large and coarse, while jadeite is cylindrical or fibrous, while jadeite has transparent colors, such as jadeite, red, and rare purple.

3. Jadeite is the most precious variety of jade, which is reflected in its color, gloss, hardness, stability and other aspects. It has a compact structure, and ruby and sapphire and other single crystal gemstones, jade is crystallized under certain pressure conditions, and the human nature is extremely high, so it can withstand great pressure without breaking, which is the characteristic of polycrystalline and cryptocrystalline silver collection.

4. Value: Jadeite is a kind of jade variety, the overall ** is higher than other varieties of jade, and the level of nephrite and jadeite ** is determined according to the quality, the better the quality, the more delicate the texture, the fewer flaws, the higher the ** nature.

5. Grading differences: The mineral composition and formation conditions of jade are relatively simple, the changes in the quality and color of Chongcong jade are relatively stable, and the time to recognize jade is relatively long, so the grading of jade is relatively easy. However, due to the complex mineral composition, the metallogenic conditions are very harsh, the texture and color change are very large, the research time of jadeite is relatively short, and the grading of jadeite is more difficult.
