Pearl whitening treatment technique

The invention relates to a whitening treatment process used for pearls. Pearls whitened in hydrogen peroxide solution are immersed in an organic solution A for a pre-treatment and then vacuumizing is carried out. Then the pearls are immersed under pressure in a fluorescence whitening liquid 1 formed by an organic solution B in which a bluing fluorescence whitening agent 1 is dissolved by 12 to 48hours under a temperature from 20 to 60 DEG C, then the pearls are cleaned and dried, then the vacuumizing is carried out again. Then the pearls are immersed under pressure in a fluorescence whitening liquid 2 formed by an organic solution C in which a reddening fluorescence whitening agent 2 is dissolved by 12 to 48 hours under a temperature from 20 to 60 DEG C, and then the pearls are cleaned and dried, then the process is finished. The whiteness of the pearl treated by the process can be greatly enhanced, and redness can be seen through the whiteness, and the brightness is brilliant and the value of the pearl can b
