Why do some jade bracelets say that they are old and moist, but they seem to have a lot of cotton in

First of all, none of the ** provided in your question are old.

Secondly, if you want to understand the above problems, you need to understand a certain concept of jadeite.

The concepts I have given below are for reference.

1. Species, species refers to the density of the jadeite structure. For jadeite with a high degree of structural density, we call it "seed old".

2. Water, the head of water refers to the transparency of jadeite.

There is no necessary connection between the above two, but under normal circumstances, the water head of the planted object will be relatively better. But this is not absolute, planting good water is short, and planting poor water is long.

3. Cotton, the existence of cotton regardless of the level of water, there are. Even if the cotton is not visible to the naked eye, it can still be seen when magnified. Compared with the old (dense structure) jadeite, cotton is more concentrated but not dispersed.

Understanding the above three concepts will solve your doubts.

Take the picture in your question as an example, the merchant describes its old moisturization. But in fact, this object, the species is not old, the structure is not dense enough, the head of the water has, but it is not long, the cotton is very obvious and very scattered, finely broken, plus the picture is a picture under the light, so from a professional point of view, this object is really general. . . The seed is tender, there is a lot of cotton, and the color is not very good.

Below I will provide one or two **, you feel for yourself, space is limited, pure obligation, don't ask too much, learn jadeite knowledge by yourself, see more and buy less.

Figure 1 is older.

Figure 2 is more tender, you can compare Figure 1 and Figure 2 by yourself

The structure is dense and the cotton cannot be scattered.

The plant is old, the structure is dense, and the cotton gathers but does not disperse.

It's just a hype concept. What does it mean to be old? A mineral can only be formed after at least hundreds of thousands of years of vicissitudes. If this is called new, then it is impossible to rely on human maintenance, and it is artificial grinding and other external materials.

Generally, pure natural jade bracelets will have a little cotton wool in them. Because cotton wool is one of the jadeite worldsNatural phenomenon

Cotton wool is a very normal natural phenomenon in the jadeite world, but if there is too much cotton wool in the jade bracelet, it is a kind of jade quality is not a good performance. It can be said that too much cotton wool in a bracelet has an impact on its value. For example, ice and glass in general.

Such a natural jadeite, the less it is more transparent, its value is relatively high.

Precautions for buying bracelets.

Carefully observe the front, back, inside, and outside of the jadeite, to see if there are cracks, or gently slide the fingers across the surface of the bracelet, if there is resistance, it means that there are flaws (may be cracks) on the firmness and service life of the jadeite, in addition, there is a pattern called stone grain, stone grain refers to the small void formed by the combination of jadeite crystals is not close enough, although the stone pattern has an impact on the appearance, but has little impact on the solidity of the jadeite.

When buying a bracelet, pay attention to some imperfections on the surface and inside of the bracelet visible to the naked eye, such as black spots, yellow spots, white "stone flowers", etc., and consider whether these flaws will affect the beauty and value.

This is a glutinous seed material, with a lot of cotton, the water head is general, the color is not prominent, and there is no emerald color. It belongs to the middle and low-end goods. The normal price is more than 1,000 to 2,000 yuan, and if there is a crack, it will be greatly discounted.

I also have a similar one, very transparent, not a lot of cotton, but also with internal cracks, and your color farming is about the same, about 200 yuan. This kind of product is considered a defective product, and it is basically cheap. However, it does not affect the wearing, and it is indeed a light green jade bracelet of a kind of ice.

The most important thing is that there is a streak of stone, maybe a crack.

Generally speaking, after we wear the jade bracelet for a long time, due to the entry of water and oil into the human body, it is possible to slightly improve the water head of the jadeite, but this takes a long time. The white cotton in the jadeite will not disappear completely, but it can fade.

It is normal for jadeite bracelets to look like a lot of cotton, which also means that the texture of jadeite bracelets is relatively average. And jadeite bracelets are natural jadeite, and there will be more or less cotton.

The increasing number of cotton diggings in jadeite is due to the oxidation reaction of the surface material of jadeite. With the time of wearing, jadeite will undergo some subtle changes under the repeated infiltration of sweat sebum. The main component of human sweat is water, followed by some sodium chloride.

Generally speaking, after we wear jade bracelets for a long time, it is possible to slightly improve the head of the jade due to the entry of water and oil in the human body, but this will take a long time. The white cotton in jadeite does not disappear completely, but it can fade.

Water, the head of water refers to the transparency of jadeite. Lead resistance --- there is no necessary connection between the above two, but under normal circumstances, the water head of a well-planted object will be relatively better. But this is not absolute, planting good water is short, and planting poor water is long.

3. Cotton, the existence of cotton regardless of the level of water, there are.

The more the jadeite bracelet wears more cotton, it is mainly caused by the influence of high temperature, tender germplasm and wax shedding. If the jadeite encounters a high temperature environment, its moisture will be slowly lost, and it will gradually dry out, and after losing the moisture, everyone will visually see more cotton wool.
