Introduction to petrified wood: The Xianyu Mountain area was a marine environment 10,000 years ago, but there were large areas of virgin forest on the top of the mountain. Due to the movement of the earth's crust, the ocean turned into land, the mountain peaks sank into the abyss, and a large number of trees were buried underground. After thousands of years of silicification, the wood becomes petrified wood. Western mystics believe that the originally rotten wood turns into an immortal gemstone after being replaced by quartz. Therefore, petrified wood has the energy properties of eternity, longevity, and immortality.
