The six-ring stone is produced in the Yellow River Basin of Baotou City, Inner Mongolia. It was formed in the Ordovician System (240 million years ago) and is a sedimentary rock. It is cut into regular blocks by calcite, and the current "ring" is formed by periodic precipitation of limonite in the center of the block. This stone has a simple and elegant color, complete and peculiar texture, and is very similar to the annual rings of ancient trees. The patterns are of different shapes and colors. It is a rare natural stone in the world. The surface of the ore body is slate-like, and each plate has its own complete shape and color ring. There are triangles, trapezoids, squares, parallelograms, etc. The smallest complete triangle pattern has a side length of only 3cm, and the largest side length is about 1.5m. The lower layer is the original rock layer, the thickest part is 1.7m, the largest block size is 3.8*1.7*0.8m, and it is a cuboid with complete color rings. Products processed with natural six-ring stone have special functions.
