60 million to 300 million years ago, this leafy tree was buried in the earth-shaking prehistoric upheaval, preserved in an oxygen-free environment, and replaced by a saturated aqueous solution of SiO2. The carbon element in the fiber structure of the tree itself was replaced by SiO2, which kept the original fiber structure of the tree and formed silicified wood. After that, it was kept at low temperature and high pressure (dynamic metamorphism), and SiO2 _ 2 hydrate was recrystallized and gradually arranged to form Yushu. The main component of Shuhua jade is hydrated silica, and its friction hardness is about 7.0, which is slightly lower than that of jadeite.

First, the rarity of tree-shaped jade: the number of silicified wood is less than one millionth of the buried amount of ancient wood, and there are very few silicified wood that can become tree-shaped jade. So far, it is unique to Myanmar, and it quickly dried up in the mining of 1978.

Second, the ornamental value of Shuhua jade: hydrated silica maintains the characteristics of silica in transparency, and the high transparency in underground environment and the impregnation of various minerals in surrounding rocks make Shuhua jade unique and colorful. It is not only transparent, but also brightly colored. If silicified wood is the inheritor of geological and historical values, then tree-shaped jade is the challenger of modern aesthetics. Tree jade not only has geographical and historical value, but also is compatible with modern people's aesthetic values. It is far superior to ordinary ornamental stones in ornamental value and has unparalleled advantages in a market with a history of stone culture of more than 2,000 years.

3. Durability of Shuhua jade: its structure is compact, its fiber skeleton conforms to the natural mechanical structure, and the hardness of silica makes it compatible with the toughness of wood and rock, which is beneficial to long-term preservation. The inherent high hardness can be compared with jadeite. Compared with other fragile fossils, Shuhuayu has its own incomparable advantages.

It has the above three characteristics, but it is absolutely unsafe to attribute tree-shaped jade to jade blindly. In the final analysis, tree jade is a fossil, a kind of tree fossil, and a fossil with jade performance characteristics. It is even more absurd to rashly attribute tree-shaped jade to ornamental stones. Tree-shaped jade inherits the living space of primitive ancient trees and is a living creation, not an inanimate one. Tree-shaped jade has both the characteristics of jade and the ornamental value of ornamental stones. It is a kind of fossil collection expressed by jade.
