Which of the following natural minerals has the strongest magnetic field on the earth today? A diamond B nine-eye stone shale (dzi beads) C crystal

From the perspective of materials science and mineralogy, the magnetism of crystals is determined by the magnetic domains of the crystal. Diamonds and Dzi beads cannot have magnetic domains due to their crystal structure. Crystals will exhibit piezoelectricity. Electric domains, but not magnetism. . . This is scientifically speaking. In terms of Feng Shui, Feng Shui comes from ancient cultural legends. At that time, there was no such thing as diamond (diamond), so there was no need to consider it. Dzi beads are an evil-proofing ornament in Tibetan Buddhism. Mineralogy only recognizes them as polycrystalline agate. They are valuable in Feng Shui. However, there are many fakes nowadays. The so-called old Dzi beads are also fake. I hope to learn from them. Get started. Crystal does have piezoelectric properties, and other properties are just legends. Jewelry is something that gives people psychological comfort, just like it. The thing above about hardness and magnetism has nothing to do with it, it’s even more nonsense
