Jade is the eternal theme of Chinese jewellery culture, and has been loved by Chinese people since ancient times. The so-called gentleman is like jade, therefore, wearing jewelry made of jade has become a symbol of identity and status. The research and excavation of jade also keep pace with the times and keep innovating. Ular orasida, nephrite has the reputation of China’s national stone, which shows its high status.

Nephrite jade is referred to as “Jade”, or Hetian jade. The world’s nephrite production area is not unavailable in foreign countries, but nephrite produced in Hotan, Xinjiang, China has the longest application history and the best quality. Shu sababli, the famous geological and mineralogist Felsman of the former Soviet Union called nephrite the “national stone” of China. “.

Nephrite is a special aggregate composed of amphibole minerals. It is the main material of ancient jade products in my country. The chemical composition of nephrite is calcium silicate, magnesium, iron, Mohs hardness of 6 ga 6.5, uneven fracture, grease luster, translucent to opaque, oq, blue, sariq, black, qizil, va hokazo. It is chemically stable, and can withstand strong acids and alkalis except hydrofluoric acid. Chinese nephrite is mainly produced in the three regions of Kunlun Mountain, Tianshan Mountain and Altun Mountain in Xinjiang.

What kinds of nephrite can be divided by color?

Nephrite jade can be divided into five categories according to color: white jade, sapfir, topaz, jasper and black jade, and other colors can be appropriately classified into these five categories.

(1) White Jade: White jade with extremely fine and flawless texture. It has sufficient water head and few cracks. It is the most precious variety in nephrite. Its top grade is called “mutton white”, which is the “king of nephrite”.

(2) Sapphire: Dark green nephrite, because the color is not as good as white jade, so the quality is one level lower than white jade, and it is still a high-grade jade material.

(3) Topaz: from light yellow to yellow-green, the one with good color is no less than white jade, so it is high-grade jade.

(4) Jasper: From dark green to dark green, the texture is not uniform and clean, and there are many dark spots and jade tendons. It is a mid-range jade material.

(5) Black jade: from ink color to light black, fine texture, lower value than white jade.
