Introduction to natural elements: In nature, it is very rare for natural elements to form single crystals. There are only 40 known natural element elemental minerals, which are extremely unevenly distributed, and only a few can form minerals. The natural elements area displays flake natural gold from the Xiaoqinling Mountains in Henan Province, natural silver from the Tongbai Poshan Silver Mine, Anhui, natural sulfur from Guizhou, and diamonds from Shandong, all of which are relatively rare mineral specimens.
