What is Hetian jade seed material with waterline?

The waterline generally refers to the irregular strip transparent line contained in the jade material, which is the line formed by the secondary crystallization in the cracks of the Hetian jade frame after it undergoes fracture. To put it in layman's terms, it's like a scar left by a wounded wound on our skin. And the "scar" inside this jade is what we call the waterline every day.

1. The waterline and jade tendon are.

In the process of Hetian jade formation, due to the erosion of external minerals, the network formed in the flesh of Hetian jade is generally called jade tendon.

There are two main differences between the waterline and the jade tendon: one is that the waterline has a clear outline and is generally a straight and elongated line, while the jade tendon looks like a cotton thread, and the outline is not very clear and generally becomes a network and circling; The second is that the waterline is generally on the surface of the jade, from the outside to the inside, and the jade tendon is generally on the inside of the jade.

2. The waterline of Qinghai jade.

The waterline is a relatively common structure in nephrite, especially in Qinghai material.

It is more common, so there are often some collectors.

It is believed that the waterline is unique to Qinghai jade. In fact, this is a relatively big misunderstanding, because the presence or absence of the waterline cannot be used as a decisive basis for distinguishing Qinghai materials.

3. Identify the waterline with the naked eye.

The vast majority of the waterline can be seen with the naked eye, and a small part of the waterline is difficult to distinguish with the naked eye, and can only be found under the strong light, which is one of the reasons why many Tibetan friends of Hetian Yu must bring a strong flashlight when they go out. Especially in Hetian jade seed material.

The waterline hidden under the skin is difficult to see even with the naked eye.

4. Hetian jade has a waterline.

The waterline is generally about the same color as the jade itself, and the jade part with the waterline is often more oily than the part without the waterline.

Although some people think that the waterline is one of the serious flaws of Hetian jade, so they don't like the waterline very much, and even think that it is a crack. However, some Tibetan friends specialize in collecting this kind of Hetian jade, especially the material with more and finer waterlines in the seed material, which may be higher than the material without a waterline of the same size.

So, if the waterline is used well, it's still a good thing.

The waterline can also be said to be a stone pattern, and it is not a crack to note it. Generally, there are more waterlines in Qinghai material, and there is no seed material in Qinghai material.

Hetian jade seed material is selected and polished by nature Hetian jade products, is Hetian jade rough after geological movement was gradually split into small pieces of different sizes, these Hetian jade fragments after 10,000 years of impact and washing on the river water, gradually formed a jade material similar to goose warm stone.

After years of washing by the river, the Hetian jade seed material gradually removed the various impurities contained in it, leaving only the most compact and hard place of Hetian jade raw stone, with a full, round, thick shape, very smooth surface and excellent quality.

Hetian jade seed material has mutton fat white jade, white jade, green and white jade, green jade, topaz, sugar jade, jasper, black jade, etc., Hetian jade seed material belongs to the scarce non-renewable resources, after a large number of mining and excavation, the stock is getting smaller and smaller, with a high collection value.

Characteristics of Hetian jade seeds

The characteristics of Hetian jade seed material are pebble-shaped, generally small block, smooth surface, because of the long-distance and long-term handling, erosion and abrasion of river water, the most dense and hard part of the jade is retained, so the Hetian jade seed material is generally of good quality, the internal quality is easy to grasp, and the material yield is high.

Hetian jade seed material has a variety of colors and textures like mountain material, and is mainly produced in several rivers with large mountain volume in Kunlun, such as the Yulong Kashgar River, the Karakashgar River, the Yarkand River and the Keriya River, as well as the ancient riverbeds and riverbed terraces near these rivers.

The "waterline" is a fault or defect in the jade, whether it is a Hetian jade seed.

The material is still Qinghai jade has a "water line", and jade without a "water line" does not exist in nature, but the seed jade with a "water line" is usually more delicate and oily.

The "waterline" itself is an in-situ stress pressure equilibrium surface, which is only seen in large pieces of jade, and experienced jade collectors regard the waterline as an important criterion for judging the texture of jade.

When the jade was formed, the geological environment was very unstable, and when the two pieces of jade were initially formed, due to the change of the geological environment, there was extrusion and re-fusion between the jade, and then the waterline was generated. The waterline is a translucent tendon-like thing inside the jade, which appears in a straight line or nearly a straight line. This is called the waterline.

The waterline in Hetian Yuli is usually considered a flaw, the hardness and density of the seed material with the waterline are slightly higher than that of ordinary seeds, as long as this is not very obvious, it can be ignored, of course, if the collection is of high grade, ** is very expensive, the waterline is one of the factors affecting its value, it is to be considered, can not be generalized

Some people think that only Qinghai jade has a waterline, Hetian jade is no waterline, in fact, it is a big misunderstanding, the waterline distribution of Qinghai jade is more messy, and the waterline of Hetian jade is more regular, the number is also very small, you can often see it in small seeds, it is not unusual, hehe

"Water line" is a defect or defect in the jade, generally appears in Qinghai jade, also called Kunlun jade, there is no such thing in the good Hetian jade, his appearance form is, a line like flowing water that can be seen under the sun, there is a wide and narrow is curved and changed, not a straight line, like a river of water is flowing, the white jade in which the complement is more transparent, easy to distinguish. Although it is a defect, but it is also his advantage, through this you can know that this piece of jade is at least true, in this era Hetian jade has been difficult to buy at a low level, you can find a waterline Hetian jade seed material your luck has been considered the best.

It usually shows one or more elongated waterline-like lines. This pattern is a natural formation of Hetian jade, not artificially made.

However, there are also some counterfeit Hetian jade in the market, and some merchants will use dyeing, infiltration and other means to create fake Hetian jade with a water line. Therefore, when buying Hetian jade, you should choose a regular merchant to buy it, and ensure its authenticity through the identification of a professional organization.

Refers to the irregular strips of transparent lines contained in the jade.

The waterline is one of the common defects in Hetian jade, it is a transparent light-colored band, and there are generally two kinds of causes, first of all, the waterline is produced when the mineral material is formed, and the waterline part is not up to the degree of retention of other parts because the content of tremolite is not reached, and the silica particles are mixed into the void of tremolite, that is, quartz, so that the local light transmittance is enhanced, in fact, the density is not necessarily lower than other parts, but the brittleness is enhanced, and it is easy to collapse in the carving, and it is not suitable to throw out good light in polishing, so it is considered to be a defect in the jade.

Secondly, there is no waterline when the ore is formed, but the waterline caused by the loss of local minerals caused by natural causes such as freezing in the river all the year round, the density of this part is low, which is only the experience of jade workers, and there has not been a scientific special discussion.

1. The tremolite content of Hetian jade has reached more than 95%, and Hetian white jade has reached more than 99%, and the mutton fat jade is even above, and the content of other mineral impurities is very small, so its texture is pure and delicate, and the structure is dense.

2. The color of Hetian jade is very pure, the color of white jade is like mutton fat, the color of black jade is like thick ink, the color of topaz is like chicken fat, it is greasy and luster, the feel is warm and soft, and the oiliness is getting better and better after playing for a long time.

3. The toughness of Hetian jade is relatively large, so it is not easy to break, and it is also very wear-resistant, and the general metal cannot cause scratches on the surface of Hetian jade, which is very suitable for carving and polishing.

Hetian jade seed material is divided into 2 kinds: mutton fat white jade, green and white jade.

1. Mutton fat white jade: It means high-quality white jade, the color is fat white, it can be slightly bluish, milky yellow, etc., the texture is delicate and moisturizing, the oil is good, the cracks are less, there can be water stone flowers, etc., the impurities are generally less than 10%, and the sugar color is less than 30%. According to the amount of sugar color, it can be further subdivided into:

Mutton fat white jade, sugar mutton fat white jade. The sugar color part of sugar mutton fat white jade accounts for 30-85%.

2. Qingbai jade: It is a variety between white jade and green jade, the color is based on white, with gray-green, blue-gray, yellow-green, brown, gray and other light-medium tones, translucent or slightly transparent, delicate and dense texture, general oil, translucent, visible cracks. According to the amount of sugar, it can be further subdivided into green and white jade, sugar green and white jade.

The difference between Hetian jade seed material and Hetian jade mountain material

1. The jade on the mountain is transported to the river of the Kashgar River in Yulong, Xinjiang after natural erosion and peeling, and is washed and eroded by the flowing water for a long time and the natural rolling and grinding in the water, so as to extract the essence from the rough, leaving the most delicate and strong part of the material.

The hetian jade seed material is relatively small, generally pebble-shaped, the surface is very smooth and round, with skin color (the loose part of the jade material or the crack is formed by the invasion of minerals). Due to the long-term erosion and natural sorting, it can be said that the seed material is an excellent jade material carefully screened by nature, and its value is second only to mutton fat jade.

2. Hetian jade mountain material is also known as mountain jade, and the local people call it Baogai jade, which refers to the original jade mine produced in the snow-capped mountains of Xinjiang.

Hetian is the collapse of the jade mountain material staring at the field of the block, there are large and small, showing obvious edges and corners, the quality is not as good as the seed jade, slightly rough, can see the graininess, no skin color, poor oiliness, some mountain materials near the outside have the color of brown sugar. Mainly produced in the Kunlun Mountains, high-quality jade is mainly distributed in high-altitude areas, the air is thin and the temperature is extremely low, which has caused great difficulties for the collection of Hetian mountain materials, and the mining is limited by the season.

Most of the Hetian jade seeds have waterlines, but many of them are not particularly obvious and need to be seen clearly in strong light. Usually many people think that the waterline is a defect of Hetian jade seeds, but generally the oiliness of Hetian jade with waterline is very good. Moreover, the value of Hetian jade seeds with good jade quality will be higher with waterlines, but it will be more difficult to carve and carve.

Most of the Hetian jade seed materials have imitation medium round waterlines, and most of the seeds of Hetian jade have waterlines, but there are many waterlines that are not particularly obvious and need to be seen clearly under strong light. Generally, the waterline on the Hetian jade seed material is about the same color as the material itself, and most of them exist on the surface of the material.

Usually, when there are cracks in the Hetian jade seed material, after being squeezed by pressure, a waterline will appear, and the outline of the waterline is relatively clear compared to the jade tendon. Many people think that the waterline is a defect of Hetian jade seeds, but generally the oiliness of Hetian jade with waterline is better.

Hetian Beiluo jade seed material with good jade quality will have a higher value with a waterline, but when doing carving, it will be slightly more difficult to encounter a waterline, but the general experienced master will make reasonable use of the waterline, so that the best of Hetian jade seed material is higher.
