I have an old friend who is a Lingbi person and knows Lingbi stone very well. As far as I know, Lingbi has produced strange stones since ancient times and was presented to the court as a tribute in the Ming Dynasty. There are many Lingbi stones, but I have never seen them as jewelry. Lingbi stone, big or small, is in a strange word. Lingbi stone is also a good stone. Lingbi stone contains a lot of trace elements, which can emit ultrasonic and infrared rays, and can be used for scraping and jewelry. Scraping board, bian stone stick, bian stone bracelet, etc. It is processed from Lingbi Bian Shi and used for adjuvant treatment of various diseases. Very beneficial to the human body.
