Qinghai material is not as good as authentic Xinjiang Hetian jade material. The quality of Laojiao Qinghai material with better quality is also very close to that of Bai Yushan material produced in Xinjiang and abroad.
The new pit of Qinghai white jade is slightly immature. The finished products carved from Qinghai white jade will generally have glass luster if polished, but the greasy feeling is not strong. At the same time, it has high transparency and big sensory head. The polished jade looks watertight, but it looks dry and oily. Because most mining methods are explosive blasting, materials generally have hidden cracks, so you can play if you like.
Brief introduction of Qinghai materials:
Qinghai has gray wax white, yellow gray white jade, distinctive turquoise and smoked jade, and Qinghai has nephrite, especially white jade. In recent years, the price of jewelry market has been rising all the way, with an increase of 300% to 500% in four years, which has high investment and collection value.
Therefore, whether it is Qinghai, Russian or seed material, as long as it is good, it can be called first-class. All jade will have three or six grades, and no matter what kind of jade, there will be good and bad.
