là 925 Gold Pawnable là gì hetian jade “Vật liệu núi”, “Nước chảy trên núi” Và “Vật liệu phụ”?

Đăng trên qua Kingjy

As a characteristic variety in the Chinese jewelry market, Hetian jade occupies a certain market share. According to different production environments, Hetian jade can be divided into “Vật liệu núi”, “Vật liệu phụ” Và “Nước chảy trên núi”, among which “Vật liệu núi” are primary mines, Và “mountain-flowing water” Và “zi materials” are secondary mines. .

“Mountain material” refers to the jade obtained from the primary mine of Hetian jade. Because it is harvested by artificial blasting, the “mountain material” of Hetian jade is of different sizes, irregular shapes, and angular, and the surface is fresh cracked surface, without rounding, and without skin.

“Mountain and Liushui” refers to Hetian jade that is naturally stripped from primary mineral deposits or accumulated by glaciers. They are generally close to the primary ore. Due to their short rolling time and short handling distance, they are usually sub-angular and poorly rounded. The block close to the primary ore is generally larger and usually has a thin crust. There is also a kind of “mountain and flowing water” produced in the Gobi area, gọi điện “Gobi material”. Its surface has special patterns left by wind and sun.

“Sub-material” refers to Hetian jade that is naturally stripped from the primary mineral deposit, weathered, and transported to the river. Generally far away from the primary ore, it is perfectly round, pebble-like, with good roundness, large disparity in size, and skins of different thicknesses on the outside. There are many colors of the husk, most of which are reddish brown, which are subdivided into autumn pear, tiger, and jujube. Sometimes the husk can also be colorless. The Jade Dragon Kashi River in Hotan, Tân Cương, is the main source of white jade, the Karakash River is the main source of black jade, and Russia also produces sub-materials.

The quality of the sub-materials is generally good, and because the surface sometimes has some different color shells, it looks particularly beautiful. Tuy nhiên, the sub-material is not the only criterion for evaluating the quality of Hetian jade, because the quality of Hetian jade is determined by its color, kết cấu, ánh sáng, kích cỡ, clarity and carving work. Due to the poor texture of some sub-materials, no one in the market pays much attention. The price of white jade mountain material with good color, texture and clarity is usually very high. Some people make fake leathers on white jade mountain materials of average quality to impersonate them. When buying Hetian jade, we must comprehensively consider its color and texture.
