It is normal that there are cracks under the ancient jade people. The "ten treasures and nine cracks" mentioned in the industry means that natural gems have cracks or flaws. The cracks in jade are caused by geological action or external force, and there is a stone pattern formed after the cracks heal, which has no effect on the texture of jade. There has always been a saying in the jewelry industry that there are nine cracks in ten treasures, which means that it is very rare for natural jewelry and jade to have no cracks at all, and there will be certain flaws, cracks, stone lines or cracks.
