The present invention provides a method for separating or concentrating nanodiamond (ND) particles containing a group-14 color center, the method including: irradiating a dispersion containing mixed particles of ND particles containing a color center of any one group 14 element selected from the group consisting of Si, Ge, Sn, and Pb (a group-14 color center) and ND particles not containing the group-14 color center with laser light having an energy equal to or higher than the resonance absorption energy of the group-14 color center; and selectively moving the ND particles containing the group-14 color center using a optical pressure generated by resonance absorption of the laser light.
