Do you know the difference between Xinjiang Hetian jade, Russian material, Qinghai material and Korean material?

Hetian jade is a kind of nephrite, commonly known as true jade. The traditional concept refers specifically to the jade produced in the Hetian region of Xinjiang. Hetian jade is a high-end jadeite with a leading brand in China. The new national standard refers to the name of jade with a hardness between 6.0 and 6.5. . How do Xinjiang Hetian jade, Russian materials, Qinghai materials, and Korean materials differ?

Hetian jade itself is not a geographical concept, not specifically the jade produced in the Hetian area of ​​Xinjiang, but the name of a class of products. In China, more than 98% of the tremolite components are named Hetian jade, also known as nephrite, tremolite, tremolite and soft jade, tremolite and Hetian jade. The jade in the narrow sense generally refers to Xinjiang Hetian jade.

Xinjiang Hetian seed material, the cloud-like texture of the jade jade is short and tight, and the oil wax is strong. The interior texture is gentle and delicate, and the jade feels excellent. The market's heavy skin seems to have become an epidemic, and loves the skin to pay more attention to jade, even a skin cover. It is bound to do the stupid thing of "buying a beggar." This also gave birth to the phenomenon of fake skin.

It is also common in many award-winning works. The skin of the jade jade is filled with tiny blisters like skin pores. The entire epidermis is the surface of the hemp pit that is moist and uneven. 20 times magnifying glass to see the surface of the seed material as a slow-moving bump, the surface layer and the shallow jade have erosion difference). Gently play with your hands and the gloss of the wax is revealed. And the better the better, the better the better.

Russian material:

Russian material is called “Russian material”. It is produced in the Baikal area. Although it is far from Kunlun Mountain, it is a typical nephrite system with Hetian jade. Russian white jade, jasper, and sugar are common in the market. Russian seed material (The market is commonly known as the majority of Russian seed material is stone leather), Russian topaz, Russian ink market is rare. Its: whiteness is superior to most of Hetian jade, the oily feeling is lower than that of Hetian jade, and the toughness is lower than that of Hetian jade. Grease-like glass luster, slightly transparent throughout, hardness between 5.2 and 5.4.

From the gloss point of view, although the Russian jade is glass luster, it has a slightly porcelain feel and is dry. After the grinding, it became dry from the deep white, and it was placed on the white cloth. It was dry in the hands. In terms of transparency, the Russian jade was brighter than Hetian jade, but due to the coarser structure and lighter feel, When worn for a long time, it will turn yellow and black. Part of the oil is still very good to get started. It has to be worn for a long time. It will be dry for a while, and Hetian jade will not be like this. Seemingly impervious but transillumination is superior to Hetian jade translucent (often said the illusory feeling).

Most of the materials are mostly agglomerate (that is, rice porridge), and the boundaries between the crystals are clear (there are spots, porridge, ice-like sensation), and some of them are visually unstructured, similar to the feeling of white marble. It is often said that the sense of stasis), some of the white material light angles appear to have a significant color cast (mostly yellow-green).

Korean material:

Korean materials are mostly blue, blue and gray. The structural state has many similarities with Russian materials. However, the difference in hardness is very large, 4-5.5 is lower than Russian. There is also a hardness of 3.5 or less, and the material quality is also very different.

(The market is mostly made up of gray and Korean materials to make Hetian jade and make seed material. The finished parts are made of wax, smoked wax, and the fake oil needs to be carefully identified.) The waxy texture is strong, and the disk is long-lasting for water-based gloss and glass. Gloss (no grease luster)

Qinghai material:

Gives a strong water-permeability feeling, white-green, light green, duck egg blue is a common variety. The shades are slightly bluish and pink. Translucent point-like fine loose cloud-like texture is a typical feature of its structure in a point-like shape, like a small grain of sand dense, sometimes there are several water lines around with "flowers." Some Golmud alpine materials are similar to Xinjiang's materials (but the blue-toned and gray-like texture at first glance is the main source of Hetian seed).

Jade species are common white jade, sapphire, tobacco, blue and white, green and white with green color. Green white jade, sapphire: green gray - dark gray green, darker and darker, partially mixed with brown spots (now part of the market is called Qinghai jasper called Qinghai jasper). Smoke: The material is fine and has no obvious structure, clear and transparent, and the jade is mixed with ink. Blue and white, similar to Hetian blue and white (Hetian blue and white are mostly seed), light black aggregates scattered in jade.
