Is it a problem to have black spots on the skin of Hetian jade?

This piece of Hetian jade is a generalized Hetian jade, the skin is an imitation of seed material, the pores are worked by people, the black spots are not a problem, and the moire on the back should have a problem there, so use the moire to cover the flaws. The real seed pores are not like this, they look very similar, but they are not natural, and they are very different from natural pores. The pores of the seed have undergone thousands of years of river erosion to become natural and smooth.

These pores are uneven, uniform and fine, with uniform shine inside and out. Under side light, the dense small holes on the uneven surface are very natural, and they are shiny with oil, and the finger touch feels very delicate. Although the shape of the artificially tumbled material is very similar to that of the real material, the surface is quite smooth, bright and has scratches, and there are no pores.

The artificial false pores have a very uniform distribution of pits on the surface, and there is no oil luster. The surface of the false pores goes straight to the pores in one direction, without the feeling of unevenness in different sizes, and some parts of the convex places are flat, which is grinded, because after sandblasting, if it is not polished and polished, the sandblasting surface is too rough and does not show the feeling of oil.

There is nothing wrong with this meaning, but the color is a little worse.

Nothing wrong, nice to see.

Hetian jade bracelets will contain black impurities, which are generally iron ions and chromium ions. And these black spots are also harmless to the body, so don't worry about it.

We know that the main component of Hetian jasper itself is tremolite, which contains many different ions, such as iron ions and chromium ions, and when they are polymerized together, they will form black spots, that is, we often see the phenomenon of black spots all over Xinjiang Hetian jade jasper bracelets, which are unevenly distributed, have no rules to follow, and are formed naturally.

Most of the Xinjiang Hetian jade jasper bracelets on the market have black spots, and there are few black spots, in the existing jasper bracelets, most of the high-grade jasper are black spots, of course, it is not excluded that some high-grade jasper without black spots, their ** is also very high.

Now the black dots can be said to be a major feature of Xinjiang Hetian jade jasper bracelets, and also as a basis for simply identifying jasper bracelets, the existence of black spots will not only not affect the quality of jasper, but will add a different mystery to jasper, plus these black spots or iron elements are beneficial to our body, so the density of black spots will improve the ** of Xinjiang Hetian jade jasper bracelet.

In life, if there are two jade bracelets with similar quality, one black spot is sporadically distributed, and one is not the slightest black spot, we had better choose one with black spots, after all, the bracelet with black spots is relatively safe, and we do not have the professionalism of those masters for the identification of jade, or it is better to insure some.

It is normal to have black spots, natural jade is more or less flawed, and generalized Hetian jasper is even more common to have small black spots inside.

The color of jasper is based on green and cyan, common green, gray-green, yellow-green, dark green, dark green and other colors, the color is softer and uniform, jasper often contains black dotted minerals, the luster is not soft after polishing, and it has a slight waxy feeling. The color is grayish-green, and fine needle-like white dots can be seen on closer inspection. In terms of hardness, it is slightly lower than the narrow sense of Hetian, that is, new, and Xinjiang.

Hello dear, black spots are speckled black objects, the color is emerald green, and the water head is often found in jadeite. If the distance between the spots is relatively far away, or if there is a solitary black spot. Jadeite is a multi-mineral aggregate, most of the black part of the jadeite finished product is amphibole minerals, is naturally formed, some people will wear it slowly and may disappear, such a statement is wrong, naturally formed minerals refer to black spots are unlikely to disappear.

1. Jadeite bracelet must not be impacted: although jadeite has the characteristics of high Mohs hardness and greater wear resistance, but at the same time, jadeite also has a great degree of brittleness and weakness, jadeite is actually very delicate, once the molecular structure in the surface of the collision may be damaged, and even dark cracks will occur, then it needs to be erased in time, 2, jadeite bracelet should not be exposed to the sun for a long time: high temperature will make the object expand, jadeite bracelet is no exception, we must not let the jadeite bracelet in the sun, Strong sunlight will increase the volume of jadeite molecules, change the quality of jade, and even affect the texture of jade.

3. Jadeite bracelets should minimize the erosion of sweat: the sweat in the human body contains salt, fatty acids and urea, etc., which will slowly erode the outer layer of jadeite and damage it, so that the luminosity and luster of jadeite will be seriously damaged, and even some serious times will make the original crystal clear jadeite hue become dull and dull.

You should be careful.

Do you have any other questions? I hope my kiss to you will be helpful, if there is no problem you can end the consultation, if you have time, please move your little hands to give a thumbs up.

There are some black spots on the jade bracelet of Hetian jade, which means that there are some problems on our Hetian jade, so everyone thinks that if there are black spots on the Hetian jade, it means that his problems in these aspects are very serious.

It is normal for Hetian jade to have black spots, especially green jade, jasper and blue and white, but too many black spots will affect the value of jade.

It is normal that most of the jade rough stones will have impurities inside, and the kind that is very pure and has no impurities at all is rare.

Hello, it is normal for Hetian jade bracelets to have black spots in them.

Especially Hetian jasper.

The black spots inside the jade are the obvious characteristics that identify it as Hetian jade.

The fact that there are black hundred points in Hetian jade does not mean that it is a fake or a problem. In the process of formation, Hetian jade will inevitably carry a little impurity. If it is jasper, Hetian jasper basically has black spots; If it's not jasper, it's other color and there are also black spots.

For example, the blue and white material is almost full of small black dots, like stars dotted inside, and some black dots are multi-answered, commonly known as "sesame paste".

The black dots in the Hetian jasper bracelet will not change after a long time. Because Hetian jasper is formed by hydrothermal alteration of ultramafic rocks, unlike white jade, which is formed from contact metamorphic rocks, it contains more nickel, cobalt, chromium and other elements than other colors of Hetian jade. Its color ranges from green to dark green, mainly parrot green, leek green, ginkgo green, etc., because jasper contains spinel components, so there are different degrees of black spots in its material quality.

Jasper is a kind of Hetian jade, in terms of mineral composition, the main mineral is actinolite containing tremolite, which belongs to the amphibole family, tremolite to actinolite similar to the same image series near actinolite end yuan.

The genesis of jasper is related to the intrusion of magnesian marble and ultramafic rocks, which is fundamentally different from other nephrite varieties, and the other nephrite varieties are derived from the metamorphic origin of magnesia marble, so the iron content of jasper is higher than that of other colors of nephrite.

As the saying goes, "perfect jade is not perfect", pure natural jade is produced in nature after experiencing complex changes in the natural environment and its long time, in addition to having beautiful and beautiful characteristics, they are also difficult to avoid a variety of defects or deficiencies in the region.

Hetian jade is not an exception, as the first of the well-known jadeite, Hetian jade has a warm and delicate material and its beautiful and varied hues, in addition, it also has different levels of defects, such as small black dots are one of the common defects of Hetian jade.

In many cases, the small black spots of Hetian jade are connected with the dirty, and no matter how beautiful the jade rough is, once it has small black spots, it will be like spots on the face of beautiful women, which will cause a certain level of harm to the decorative art of Hetian jade. In essence, the dirty spots in Hetian jade are actually the accumulation of other mineral components in the jade, the most common being dark brown or dark brown iron, which is mostly stored in the cracks of the jade, which can be observed with the human eye.

It must be noted that there is a difference between the small black dots in Hetian jade and the ink dots in the cyan material, and the existence of small black dots can often be seen in Hetian jasper, and the thorough and neat Hetian jasper is basically not there, so from another perspective, the small black dots are just the key markers to confirm the pure naturalness of Hetian jade, and it is not a defect.

1 There are black spots in Hetian jade, which is impurities. 2. Hetian jade is indeed the purer and more expensive, the texture must be tight, and the density and hardness must be excellent to be good**. 3 A little black spot is a normal phenomenon, jade is like a person, more or less has its own shortcomings, that is, flaws.

4. If you like jade, you must tolerate his shortcomings.

A lot of Hetian jade has black spots, and this kind of black spot is also called blue and white material.

Yes, natural minerals, there will be some impurities in them

Blue and white and jasper all have black spots.

Yes, there are. The value of having black is lower.

Some of them are, possibly impurities, which can affect the value.

19.Is Hetian jade seed material necessarily better than mountain material?

Now the recognition of Hetian jade seed material in the industry is very high, and it has also been pushed up, which is usually much more expensive than mountain material. However, whether the seed material is necessarily better than the mountain material also needs to be treated.

Tales of jade history.

The more Hetian jade wears black spots, it may be the reason for the lines, and the more lines on the surface of Hetian jade, grease and dust will gather in it and gather into black spots. It may also be the reason for the texture, some jadeite has black spots on the surface itself, and people will wax on the surface in order to cover up the traces.

The maintenance method of Hetian jadeWhen Xinjiang Hetian jade is maintained, if it is a new jade, it is best not to make it contact with sweat for a long time, and it is best to let it soak in water regularly to make it more shiny. In order to make Xinjiang Hetian jade more oily, it can also be oiled and maintained, but the good quality of the jade does not need to be oiled.

When maintaining Xinjiang Hetian jade, it is also necessary to avoid making it hit to avoid cracking. Maintenance method of Xinjiang Hetian jadeWhen maintaining Xinjiang Hetian jade, if it is new jade, it should be avoided to contact it for a long time.

The black spots of Hetian jade are usually a natural flaw, Xinjiang Hetian's blue and white materials (mountain materials, seed materials) are named because of black spots, and Xinjiang Hetian jasper (mountain materials, seed materials) will also have different degrees of black spots or markings, which is one of the signs of Xinjiang Hetian jasper.

Hardness is one of the important indicators for the identification of Hetian jade, which refers to the ability of the mineral to resist the intrusion of external mechanical forces (such as engraving, pressing, grinding, etc.).

In the jewellery industry, hardness is generally used as an important marker to distinguish gemstones from jade. The hardness of gemstones is generally above 7 degrees on the Mohs scale, and the hardness of jade is generally 4-7 degrees on the Mohs scale, and below 4 degrees on the Mohs scale is usually called colored stones or carved stones. It has high hardness and good polishability, which can make jade shiny and convenient for long-term preservation.
