Jade snail fossil is a natural fossil. The Paleozoic ocean, which was formed 400-600 million years ago, gradually experienced the process of crystallization and silicification after a long time and the role of natural environment. This fossil is a non-renewable natural heritage with high historical and scientific value. Jade snail fossils have beautiful colors and textures, and also have certain applications in the production of jewelry and decorations. With the increasing scarcity and awareness of protection, new jade snail fossils have been rarely exploited. Most of the jade snail fossils sold in the market come from early discovery and mining.
