Ambidextrous magnetic circularly polarized luminescence (MCPL) and redshift in photoluminescence (PL) spectra are observed from two types of achiral soluble diamagnetic perovskite‐Pb‐quantum dots in toluene solution at room temperature, when subjected to external north‐up and south‐up magnetic fields of 1.7 T. The magnitude of the MCPL,gMCPL, is in the order of |gMCPL|=10−3within a wavelength range of 480–580 nm. The wavelength and the sign of the MCPL spectra can be controlled by the types of perovskite constituent atom and the direction of the magnetic field, respectively.
