The overall quality is on the high side, so the market price is relatively higher than other producing areas, especially high-quality sub-materials. Xinjiang white "sub-material" is oval, generally small in size, smooth in shape and dense in texture. White is the best color, and skin is an important appearance feature of the material.
Xinjiang white jade "mountain material" is large in size, irregular in edges and corners, and thicker in texture than sub-material. The colors are mostly blue, white and gray. "Gobi material" varies in size, mostly flaky, with smooth surface, often corrugated surface and Chacon with different sizes, and its texture is fine, dense and hard. "Shanshui" and "Gobi material" are similar in appearance and texture, but slightly larger in size and whiter in color.
Extended data:
According to the national standard GB/T 16552—2003, Hetian jade has no origin meaning, that is, nephrite with tremolite as the main mineral can be called Hetian jade, and Hetian jade can also be called nephrite. ?
In addition to Xinjiang, China, there are more than 20 tremolite jade deposits in the world, which are distributed in more than 20 countries and regions: Russia, the United States, Brazil, Canada, Australia, Poland, New Zealand, South Korea, North Korea and Taiwan Province Province. Among them, Canada's output ranks second in the world. These deposits belong to serpentine tremolite jade, mainly jasper, and white jade is produced in Russia, South Korea and North Korea. Only Hetian jade in Xinjiang belongs to non-serpentine tremolite jade because of its special geological formation.
