What are the structure and identification methods of Hetian jade?

Many times we say that buying jade depends on the structure, so what is the structure? Can you tell the origin of Hetian jade from the structure? What do you think? The following is the structure and identification of Hetian jade I compiled for you, hoping to help you.

What is structure? First of all, let's talk about what is structure. In nature, all kinds of stones can be seen everywhere. These stones have different shapes. Rocks are composed of minerals, some are granular, some are fibrous, some are flaky and columnar, some are crystalline, some are conformal, and the crystal morphology is not visible, some are coarse and some are fine. Some minerals are arranged in parallel, and some minerals are interspersed, interwoven and filled with each other. This is the structure of the rock. Structure can also be simply understood as the composition of matter.

mineral

So what is the structure of Hetian jade? There are many common structures of Hetian jade, among which felt structure is the most common and typical. In this structure, tremolite fiber is very fine, and its outline cannot be distinguished under optical instruments. Mineral fibers are evenly distributed, densely distributed and directionless, just like carpets made of animal hair, hence the name felt structure.

Confucius said it two thousand years ago? Is there jade or wood? what's up Collapse and not disperse? Talking about the basic characteristics of this mineral.

Differentiation and Analysis of Hetian Jade Structure and Identification Structure Because of different producing areas, the structure of each jade species is also different. The following is a brief introduction to the texture structure characteristics of each jade species.

Structure of seed material

The structure of seed material is a typical felt-like interwoven structure with fine particles and fine structure. Most of them are felt-like and velvet-like structures interwoven with fibers, and some jade materials are good jade, and even the internal structure of jade cannot be observed.

We can often see the words of fiber interwoven structure on some certificates. In fact, Hetian jade in a broad sense is a fiber interwoven structure, while the seed material is generally written as a felt-like fiber interwoven structure, and the structure of the seed material is similar to a cloud texture. A good seed material structure is also arranged like fish scales, very neat and almost perfect, and the fine structure looks like a carpet.

However, the felt fiber interwoven structure is not unique to hetian seed material, and the mountain material and Russian seed material with better texture are also felt fiber interwoven structures.

Qinghai Liao

Regarding the structure, Qinghai material has a unique sugar-like structure, which is not as oily as seed material, but it cannot be concluded that the density is not good. Just look at the delicate structure, but this exquisiteness is different from the seed material, which is not interwoven enough, thin but permeable.

Seed materials are generally dominated by flocculent structure, and unstructured ones are rare. Generally, if you can visually feel sticky, it will do. On the other hand, the structure of Qinghai material is very fine. In many cases, the structure of the blue sea material can't be seen when it is polished, but it is not fine in structure, but the structure of the cloud floc is underdeveloped. After zooming in, you will find that it is actually more of a fine point structure. If you look at the blue ocean material with the light on, you generally feel that the particles are smaller, but the flowers are large, so it is easy to feel uneven.

Qinghai materials also have a common feature: the waterlines are intertwined vertically and horizontally, and some waterlines are concentrated together to form a feeling of a pool. With this structural feature, it is generally Qinghai material. Of course, there are some such characteristics in Yutianshan materials.

Russian materials

The interior of Russian material is blocky texture with loose texture, and the color difference between freezing point and cloud is large and obvious. It's oily and looks a little raw.

Different from the tenderness of seed material, Russian material looks rough and crazy. Russian materials are generally coarse-grained structure, massive structure and patchy structure, but some of them are too close to see the structure.

Russian materials are mostly made of jade flowers, which look like rice grains in paste, which is the characteristic of Russian material structure.

Korean materials

The structure of Korean material is similar to that of Russian material, but it is looser. In addition, Korean materials are yellow-green tones, and you will feel that way if you watch them too much.

Korean materials are mostly loose in structure, a bit like? Rice porridge? .

The internal structure of Korean materials is very rough and granular. The raw rice grains in Korean Otawa mash soup have the same structure, including irregular white rice grains and immature rice grains. Many Korean jadeites are fairly clear after polishing, but as long as they are polished, they will be found loose.

Structure and Identification of Hetian Jade It is not so easy to distinguish the place of origin from the structure, because the structure of jade is diverse and complex, some Qinghai materials are very similar to seed materials, and some Korean materials are very similar to Russian materials, so it is very difficult to distinguish the place of origin from the structure. In addition to distinguishing the origin from the structure, the structure is also closely related to jade, so how to distinguish jade from the structure?

With what? Structure? The most relevant thing is fineness. For jade with good color, the internal mineral structure is relatively equal in size and arranged regularly. When we look at the interior of jade with transmitted light, we can feel that the interior of jade is very clean and tidy. However, the density of jade with good fineness is not necessarily good, that is, the compactness of mineral components in jade is not necessarily high, and jade with good fineness does not necessarily show oily feeling.

Usually, the fine flocculent structure is distributed in the internal structure of Hetian jade with good quality, and the arrangement is fine and tidy. The finer the flocculent structure, the better the quality. For seed materials, the finer the floc, the better. For seed materials with high whiteness, the flocculus will be slightly larger, with high whiteness, compact structure and expensive price.

? No structural lighting?

Players often say a word? Lighting is unorganized. However, there are many misunderstandings about unstructured lighting.

Let's talk about it first? Light it? Lighting can be divided into backlight and sidelight. Backlight is to observe impurities, dark cracks and dark injuries in jade materials, while sidelight is to look at the structure. Backlight can't see the structure, and it is a lie to say that Hetian jade has no structure, because it can't see the structure.

Secondly, there are many materials that have no structure under naked eyes or natural light, but no matter how tight jade is, it will have a little structure under strong light, so it is unlikely that there will be no structure at all. If it really has no structure at all, it is probably a feeder. Sometimes the side light can't see the structure, but the material is small or thin, or the skin color coverage is not obvious.

Secondly, is there a material without structure? Not necessarily. Some seed materials without structure are often tender, not rich enough and not oily enough. No structure is relative, it is ok to pursue no structure, but don't go astray.

There are few unstructured seed materials, but some jade species can almost do it? No structure? For example, duck egg green, good sapphire, taqing, Hemu fish and so on. But this kind of unstructured means that in the case of light source, the naked eye can't see the structure clearly, and it is relatively unstructured.

Moreover, everyone should understand that the structure is only one aspect of evaluating the quality of jade, and the quality of the material still depends on a comprehensive perspective, such as color, oiliness, maturity, whiteness, defects and other factors, in order to judge the quality of a jade material.

Finally, we should distinguish the jade species from the structure. It takes some experience to see the structure, and the products of nature are always changeable. Seeing structural features can only be used as an auxiliary method to distinguish materials. It is impossible to identify a material by only one structural feature. Often the same material will have different structural characteristics, and materials with the same structural characteristics may also belong to different kinds of materials, which cannot be generalized. Therefore, the structure must be combined with other features, otherwise it is likely that the more you look at it, the less you understand it.
