Expensive. Jade used in jewelry in Bi Hui, Yunnan Province is relatively scarce, because the formation of jade requires specific geological conditions and long-term natural action. Jade resources in Yunnan are relatively limited and have unique origin characteristics, so the rarity is relatively high and the supply is relatively small, thus pushing up the price. Yunnan Bi Hui Jewelry pays attention to the selection of high-quality jade raw materials, fine processing and carving. High-quality jade has good texture, color and transparency, and there are no obvious flaws.
