Jade is a mineral. There are two kinds of jade: soft and hard. Usually, jade refers to nephrite. It belongs to one of the most common jewels. According to the local chronicles of Tengyue written by Qing Jinshi Cun Kaitai, "Tengyue was collected by jade workers, made into utensils and sold in Yunnan provinces. Top grade jadeite is mostly sent to eastern Guangdong, Shanghai, Fujian, Zhejiang, Kyoto and other places. "
Basic introduction:
China is the earliest and most extensive country in the world to exploit and utilize jade. There are many records and names in ancient books, such as Shuiyu, Heritage Jade, Peiyu, Xiangyu, Nephrite and so on. Tremolite nephrite unearthed from Chahai site in Fuxin city, Liaoning province is about 8000 years ago (early Neolithic age), which is the earliest known real jade in the world.
The most famous jade in China is Hetian jade in Xinjiang, which, together with dushan jade in Henan, xiuyan jade in Liaoning and lantian jade in Shaanxi, is called the four famous jade in China. Jade is one of the noblest minerals. Emerald is rich in many elements, such as zinc, iron, copper, manganese, magnesium, cobalt, selenium, chromium, titanium, lithium, calcium, potassium and sodium. The embellishment of jade can eliminate impetuous hearts, and the color of jade can delight bored hearts.
The purity of jade can purify a dirty heart. Therefore, a gentleman loves jade and hopes to find natural aura in the jade body. Jade is the beauty of stone, with positive, moist and pure color. The same is true of precious stones. Its value does not depend entirely on the ingredients, but color, texture and sculpture are often its value.
