How do you think jadeite jewelry can distinguish the real from the fake?

You have to see the color of jadeite jewelry and its texture, the color and texture of good jewelry are not the same, through this it is good to identify the authenticity of jadeite jewelry.

The first is that when you buy, you must go to a regular manufacturer to buy. The second is to be sure to look at their certificates and anti-counterfeiting logos. If it is of relatively large value and has collection significance, it is best to find an appraiser to identify it.

Jadeite can look at its color, and then the probability of green and red, but also look at its luster, transparency. Jewelry can be seen in its size, color, luster, as well as the feel and weight of holding it in the hand.

Good jadeite jewelry is definitely not the same as bad ones, they are not the same in terms of color and materials, if you don't know much about the control of a jewelry, you can go to a professional jewelry store to ask.

One look at the color: natural jadeite is natural in color, unevenly distributed, and the green trend is extended. Second, look at the polished surface: the polished surface of natural jadeite is delicate and smooth, showing a strong glass luster with grease, if you look closely on the polished surface, you can see slightly transparent to opaque white fibrous crystals.

Everyone knows that the powder is very transparent, and it is very bright, if you really can't tell the difference, then you can go to those jewelry stores and ask someone to help you distinguish the real from the fake.

It can be identified by observing the fineness, the color of jadeite jewelry should be relatively easy to identify, and there is also listening to the sound, gently knocking on the jewelry, the sound made by jadeite jewelry should have certain characteristics.

Under the light, we should look at the luster of the surface, as well as the hardness of the jadeite jewelry, the density of the jadeite is relatively large, the feel will be heavier, and the sound of percussion will be more crisp and pleasant.

This kind of thing should be tested according to its material and with the help of some more specialized machines, and sometimes there is no way to test the authenticity of a jadeite just by looking at the color and quality.

The most direct way to identify the authenticity of jadeite is to observe the appearance.

Take the jadeite to the light or shine it with a flashlight to see the impurities, cracks, crystal distribution, transparency, color, etc. in the jadeite. It has few impurities, small cracks, uniform crystal distribution, translucency, and the best color is emerald green. The color of real jadeite is evenly distributed, the color is very natural, it looks clean, even if it is a jadeite with impurities and black spots, the distribution of black spots is also natural.

Fake jadeite because it is dyed by glue, the green of the jadeite looks very deliberate, the color is relatively gray, if the fake jadeite soaked in pickling, the white place looks fake, like the color of the clothes after being bleached by stupidity. Of course, seeing is a science, and it is impossible to master it all at once. At least, many superficial phenomena are particularly obvious, and Pei Lu can easily detect them even if he is not an expert, so he has a few more eyes.

How to maintain jadeite best

1. Let the jadeite take a bath often.

This method is also called "water culture". Jadeite is afraid of drying, if it is not hydrated for a long time, the water inside the jadeite will volatilize. As a result, the jade will dry out, the luster will darken, and the water head will also be affected.

So every two or three months, you can soak your jadeite in pure water for half an hour, brush off the dirt with a soft brush, and then dry it with a soft cloth.

2. Isolate the air.

Jadeite is naturally formed over thousands of years in a low-temperature environment with a ground and bottom zone. Therefore, it is afraid of high temperatures and sun. Too high a temperature will cause the jadeite to lose water inside, so that the jadeite is no longer moist and shiny.

Therefore, when we usually wear it, we should be careful not to expose it to the sun, and do not let it be close to a high temperature environment. When not wearing, wrap it in a sealed bag or household plastic wrap and store it away from light.

Jadeite A goods: refers to jadeite whose color and texture are maintained in a natural state and have not undergone any artificial treatment.

Jadeite B goods: refers to jadeite that has been bleached and treated with strong acid. The production of "B goods" is generally selected with green, poor texture, opaque, and many impurities of inferior jadeite, first soaked with strong acid, and the impurities in it are dissolved to remove impurities, so that the main color other than the color such as gray yellow, gray and black color is removed, so that the main color is more vivid, and then use branches or other adhesives to fill the voids and cracks that appear after dissolution, so as to increase strength and transparency, so some people call it bleached jade.

Characteristics of jadeite B goods identification: blurry and opaque under the projected light, with large network lines, and the edge of the green mass is not clear.

Jadeite C goods: refers to the dyeing of jadeite, also known as dyed jade, because this jadeite mineral particles are generally colorless, and dyeing can often only be along the intergranular voids or cracks, and often constitute a green reticulated or linear distribution, especially in the green at the cracks, either deeper than other places, or shallower than other places, and there is no extension to both sides, there is no transition gradient phenomenon, darker than other places, is the crack is larger than other places in space, precipitation of more coloring material, than other places are lighter, It is the result of fading treatment afterwards to avoid revealing staining flaws, and these features are more clear under magnifying glass.

Characteristics of jadeite C goods identification: the color is darker in the visible cracks under the projected light.

Jadeite can be divided into jadeite A goods, jadeite B goods, and jadeite C goods, of which only jadeite A goods are completely natural and have not been artificially processed. Because it is a natural jade, the surface of jadeite A goods shows a glass luster, a compact texture, a natural layered color, and may have some natural impurities.

1. Emerald property: Regardless of the raw material or finished product of jadeite, as long as you carefully observe on the polished surface, you can usually see the interwoven structure of spotted crystals. Two forms of jadeite crystals can be seen on a piece of jadeite, one is a slightly larger granular porphyry, and the other is a small fibrous crystal intertwined around the porphyry.

Under normal circumstances, the size of the porphyry particles of the same piece of jadeite is uniform.

2. Stone flowers: There are small clumps in the jadeite, and the white fibrous crystals with slight transparency are intertwined with stone flowers. The difference between this kind of stone flower and spotted crystal is that the porphyry crystal is transparent, and the stone flower is slightly transparent to opaque.

3. Color: The color of jadeite is uneven, with different shades of green or black on the base of white, lotus pink, oil blue, and bean green. Even on the green base, there are shades.

4. Luster: Jadeite has bright luster, good polishing, and bright and soft strong glass luster.

5. Density and refractive index: jadeite has a high density and sinks rapidly in tribromomethane, while nephrite, serpentine jade, prehnite, quartzite jade, etc., which are similar to it, are suspended or floated in tribromomethane. The refractive index of jadeite is about (spot method), while other similar jades are lower.

6. Inclusions: The black mineral inclusions in the jadeite are mostly melted, and the edges of the particles are loose clouds, and the green color becomes deeper around the black inclusions"Green follows black"said.

The main identifying characteristics of jadeite are: uneven color, green trend extension; strong glass coating with grease; interwoven structure of variable speckle crystals; It has a cool feeling, and the color does not change under Charles's mirror.

I heard that if you scratch it on the glass, there will be the same mark as the diamond cut, that is, the trace.

I think the landlord can go to the store to see, can learn a lot, my jade pendant is heirloom jadeite, the consultant over there mm is very enthusiastic to teach me how to judge, you don't understand can also go over to ask people. I remember judging mainly from three aspects: the color of the jadeite, the purity of the crystalline and the workmanship. In particular, color is very important, generally speaking, jadeite is the best colorless and transparent, pure as water, but usually jadeite has more or less color.

The color of jadeite can best determine the quality of jadeite, and the more delicate green the color of jadeite, the more valuable; The gloss should be bright, and the color that cannot be dark should have a uniform tone in addition to green. The quality of jadeite with tight internal crystalline structure is relatively good, and the transparency is also high, and the "glass species" is this kind of jadeite with high transparency, because the jade itself is rich in chromium and forms ice jadeite, which is very valuable and.

The third, weight. The weight of jadeite is actually quite heavy. If it is a real jadeite, put it on your hand and you will feel a noticeable weight.

If it is a fake jadeite, because it has been processed, the structure has been destroyed, so the weight will be greatly reduced, significantly reduced, and there will be no heavy feeling.

Fourth, sound. This method is to tie the jadeite with a rope and hang it in the air, and then take a wooden stick and gently tap it. If it's a real jadeite, it's crisp, and if it's a fake jadeite, it's dull.

Fifth, hardness. This method is to scratch or scrape with a hard object such as a sharp nail or knife, if it is true, it will not leave any marks, and if it is fake, there will be obvious marks.

Sixth, dripping. A drop of water, if it is real, will take on a shape on the jadeite, in the shape of a dewdrop, and if it is fake, it will slide down.

Good jadeite is usually relatively good in color and workmanship. The color is more bright and transparent, there is no messy pattern, it looks better, and the workmanship can not be rough.

First of all, look at the color, if the color of the jadeite is more transparent, there are not too many impurities, you can also knock on the jadeite, to see if there will be a crisp sound, if there is that it is true.

There are many ways to tell by the color of the jadeite, by the drip method, or by looking at the certificate of the jadeite. Knowing the water color flaws of jadeite can distinguish the real from the fake.
