Price of Guangdong Green Jade
As one of the five famous stones in China, Guangdong green jade stone, the current market price is generally undervalued. It is revealed that the "Guangdong Local Standard (Guangdong Green Jade)" and "Guangdong Green Jade Geographical Indication Product Protection" will be introduced soon, and the market price of Guangdong Green Jade is expected to double in the next two years.
Ancient seals and new frozen stones are hot spots for collection
Guangdong green jade stone is produced in Guangning County, Guangdong, and the collection is concentrated in two categories: ancient seals and new modern products. Among them, Guangdong green ancient seals of the Qing Dynasty are the most valuable, and the Guang green jade seals engraved by famous artists from the Qianlong to the Republic of China are sought after by collectors, while the Guangdong green seals of Qi Baishi and the famous artists of the Xiling Printing Society are hot spots for collection.
The new collection has a wide range of categories. Currently, there are 60-70 varieties of green jade, with frozen stone as the top quality, of which "green jelly of Venus" and "blue sky jelly" have been extinct, and are hot spots for collection. "Although green jade is characterized by its green color, the red jelly stone (i.e. Guangdong red) is more rare and precious." said Lin Qiang, director of the Guang green jade culture research center at Guangdong University of Finance and Economics.
"Top quality jadeite and Hetian jade are mostly used for jewelry, with diverse levels of consumption. Guangdong green jade is not suitable for jewelry, should be based on the performance of elegant cultural connotation, aimed at high-end art market. Guang green jade is not well known, the current market price is difficult to compare with topaz, jadeite and other jade species, but its upside is huge." Lin Qiang believes.
Guangdong green jade is still a blind spot for collection
As far as the current market situation is concerned, the price of Guangdong green jade raw materials has increased significantly. It is understood that before 1984, most jade resources are used by miners to make "talcum powder" and other industrial raw materials, when the raw material price of 1.7 yuan / 100 kg. 1984, after the establishment of jade carving factory in Guangning County, jade raw material prices are gradually rising. For example, the above "white eye stone" varieties, its price rose from 12 yuan / 100 kg to the current 150 yuan / kg.
"For example, a small carving of Ouyang Liangmu, a master of arts and crafts and a titan of Chinese jade carving, sold for only 1,000 yuan in 1985, and was sold for 380,000 yuan at the end of last year." Lin Qiang revealed, "At present, the collection of wide green jade is still a blind spot, and the domestic market is circulating a number of wide green jade Qing Dynasty seals returned from Japan, which are seriously undervalued, with auction estimates mostly in the range of 10,000-20,000 $."
Lin Qiang also said that many collectors are still in a wait-and-see situation, waiting for the "Guangdong Provincial Local Standard (Guang green jade)" and "Guang green jade geographical indication product protection" two regulatory documents, with a view to issuing quality testing certificates for Guang green jade collections, as well as the origin of the logo. "If these two documents can be successfully introduced, the quality, credibility and industrial development of Guanglv jade will be regulated and guaranteed, and the confidence and recognition of collectors will be significantly increased. It is expected that the price of Guang green jade collections is expected to double in the next two years."

Mr. Cheng Dajun, a famous Chinese jade expert, GAC jade appraiser, vice president of Guangdong Provincial Jade Association, and first vice president of Asian Jewelry Federation, wrote an article "Guangdong Green, one of the "Five Great Stones" of China" more than 20 years ago. He gave a detailed description of the stone and compared it with Tian Huang and Chicken Blood Stone, giving it a very high evaluation. The former president of the Buddhist Association of China and the late famous calligrapher Mr. Zhao Puchu was pleased to inscribe the stone with the words "Guangdong Green, the treasure of stone".
According to the Guangning County Records of the Qing Dynasty, "The stone of Yun Chaoshan (now Mugwai Mountain) is colorful, warm and chestnut, and is sold by merchants for carving seal heads. Guangdong green stone is delicate, warm and moist like jade, with few impurities, moderate hardness and easy to process, and is a rare gemstone. It is also a precious material for making arts and crafts and seals.
