As a special kind of nephrite, Jadeite is deeply loved by consumers, and its market price far exceeds that of ordinary white jade.
Jade green jade, light green, its green features like tender green jade, and the green color of sapphire and jasper is obviously different. This part of green nephrite is rarely produced separately, but attached to one side of white jade and white jade raw materials or forms a sandwich and agglomerate. The distribution is often related to flocculent and spotted stone flowers.
Among the finished products, there are all green (green), but also in the white jade, blue and white jade carving ornaments constitute a pretty color, which is rare in the previous Hetian jade products. Its full-color and pretty-colored products have become a hot spot for jade collection. Some people in the industry call it Qinghai Jade, Kunlun Jade, so the name does not meet the national gemstone name standards, easy to cause confusion.

In the ore belt, the emerald color is often distributed along the cracks, so the jade material is more gambling. This distribution characteristic also determines the low yield of the bracelet with green color, which is one of the reasons why the value of the jade carving is more valuable. In addition, the emerald color is occasionally distributed in other jade species of Kunlun jade, and its finished products tend to have a variety of pretty color combinations, so it is extremely precious.
The jade in the nephrite is extremely rare. There is a small amount of output in Russian nephrite, but most of its emerald color is more boring, and the color of the green color is not enough. In the many mines affiliated to Xinjiang, the jadeite with jade has not yet been discovered.
