Which material is the best Hetian jade, and how many materials are Hetian jade?

If it is analyzed from the jade quality and Tianyu is divided into several materials, among which the jade quality of mutton fat jade is the best, and Hetian jade can be divided into mountain material, seed material, mountain water and Gobi material because of the different formation environment, among which the texture of the seed material is the best, and the jade quality of the mountain material is relatively poor.

Hetian jade is generally divided into seed material, mountain material, mountain water and Gobi material according to the landform of the formation area. According to the production area is divided into generalized Hetian jade and narrow Hetian jade, narrow Hetian jade is Hetian jade from the Hotan area of Xinjiang, generalized Hetian jade is more, as long as the tremolite composition reaches more than 95% can be called Hetian jade, there are more Qinghai materials, Korean materials, Russian materials and so on ......

There are many ways to divide this kind of material, and then, if we divide it according to the grade, we will divide it into three ways: the upper grade, the middle grade and the inferior grade, so we also know it. This can be done in this way.

According to the national standard samples by color classification, Hetian jade is divided into 6 categories: white jade, green and white jade, green jade, jasper, black jade and sugar jade.

1. White jade. Refers to white nephrite, the traditional jewelry industry has different names for different degrees of white nephrite, such as mutton fat white, pear blossom white, snowflake white, ivory white, fish bone white, brown rice white, chicken bone white, etc., among which the mutton fat white (like clotted fat) is the best, which is unique to Hetian jade. Mutton fat white jade is very small in quantity and has a high value.

2. Green and white jade.

Refers to nephrite between white jade and green jade, which seems to be white but not white, and is like green but not green. The ancients used this name.

3. Green jade. The traditional Chinese "green jade" is dark green with gray or green with black. Green jade is the most common, ranging from pale cyan to a deep cyan of shiny green. Green jade is the hardest of nephrite, but its color is not as beautiful as white jade, and its value is lower than that of white jade.

4. Jasper. Nephrite is green to dark green, sometimes with black spots, and its green color includes parrot green, pine green, and ginkgo green. In terms of the status of Hetian jade in ancient Chinese jade, the one that transmits light and is as moist as spinach is the top grade, and the green with gray is the lower grade, but it is by no means the "jasper" or "jasper" in quartz jade. The best jasper is as jade in color, and ancient women often used jasper as a headdress, and the story of the jasper hairpin is an example.

5. Moyu. Nephrite, which ranges from black to pale black, and sometimes has a "blue-black" color, is often accompanied by green jade, and its luster is duller than that of other jades. Its black distribution is either dotted, or cloud-like, or pure black, and its names are: dark cloud piece, light ink light, golden mink beard, lady's sideburns, pure pitch black, etc.

In the whole piece of jade, the black color is deep and light, and even on a piece of jade that is mainly black, it will be mixed with cyan, or even white, among which the black color of the black jade is caused by the micro-scale graphite.

6. Sugar jade. Refers to nephrite jade that is blood red, brown sugar red, purple red, and maroon-red, among which blood-red sugar jade is the best, and it is mostly subordinate to white jade and green jade.

Hetian jade is mainly divided into four materials:

1. Mountain material: jade blocks without weathering surface skin or with a very thin weathering layer, mostly primary ore mined from the outcrop of the mine or the face of the palm, also known as mountain jade, ballast jade, called "Baogai jade" in ancient times, refers to the original jade mine produced in the snow mountains of Xinjiang region.

2. Mountain flowing water: Mountain flowing water is Hetian Yushan flowing water material, which is better than mountain material and second only to seed material. The primary ore produced at high altitude of Hetian Yushan material is rolled down to the foot of the iceberg by natural factors, and is transported and washed by natural denudation and debris flow, rain and glaciers.

3. Sub-material: Sub-material, also known as "seed material", "child material", "sub-jade". The seed material is a pebble-shaped jade material naturally formed in the river, with a seed skin on the outside.

After long-term weathering, it is peeled into pieces of various sizes, which collapse on the hillside and are washed into the river by rainwater. When the river dries up in autumn, the jade collected in the riverbed is called seed material.

4. Gobi material: Hetian jade Gobi material is a manifestation of Hetian jade. It is mainly produced in the Gobi Desert in southern Xinjiang, and is formed by the long-term exposure of the original ore to the surface through weathering and caving, and long-term interaction with wind, sand and rain.

The moistness and texture of Gobi material are obviously better than that of mountain material, and Gobi material is comparable to seed material in Hetian jade.

In the academic category, Hetian jade is divided into four types: mountain material, seed material, mountain water material and Gobi material.

Among them, Xinjiang Hotan seed material has the best quality and higher collection value.

Hetian jade mountain material is a medium and high-grade jade raw material.

Hetian jade mountain material, there is no strict regulation on the place of origin, as long as it is in Xinjiang, the jade ore mined on the snow mountain is called Hetian jade mountain material, its quality is also the standard of high-grade Hetian jade, compared with Hetian jade river material, the quality may have a pure difference, the cortex and the edges and corners have changed, its cortex is thicker, the edges and corners are not so rounded, this is understandable to bury only orders, after all, this is the jade material excavated in the mountain, without the washing process of the river, the natural quality will be worse.

After polishing, the Hetian jade mountain material exudes the unique luster and luster of Hetian jade, as well as the perfect softness and translucency, and the fat white tone of Hetian jade mountain material is also high-grade and white.

The hierarchical division of Hetian jade

Hetian jade can be divided into eight grades of mountain spikes, which are white jade, green and white jade, green jade, jasper, black jade, topaz, sugar jade and red jade. Among them, the whiter the white jade, the better, but it should also be moistened. Green jade is the most abundant variety, which can be subdivided into colors such as willow green, turquoise, gray green, and green yellow.

Qingbai jade is a transitional variety between white jade and green jade, and its upper limit is close to white jade, and the lower limit is close to green jade.

The black jade is the best with the color of "black as pure lacquer", and the topaz is the best with the color of "yellow as a steamed pear". Sugar jade is a translucent white or pale yellow jade with a soft texture and sometimes defects such as locks, cracks, and impurities. Ruby is an extinct species and mostly exists only in legends.
