Problems solved by technology

For example: use the impurity and decontamination effect of organic solvents such as methanol and acetone to soak pearls to achieve the effect of increasing the pearl's smoothness and gloss, but the disadvantage is that the effect is not very obvious; The decontamination effect is used to soak pearls, especially the complexation and removal of non-ferrous metal ions in pearls, and also achieve the effect of fading and enhancing luster, but the disadvantage is that the effect is not very obvious, the action time is too long, and due to the strong alkali of ammonia water Sex, too long time will cause the luster and permeability of pearls to decrease

Description

(1) Technical field [0001] The invention relates to a pearl and a preparation method thereof. (2) Background technology [0002] In recent years, many workers have carried out research on pearl enhancement treatment technology. For example: use the impurity and decontamination effect of organic solvents such as methanol and acetone to soak pearls to achieve the effect of increasing the pearl's smoothness and gloss, but the disadvantage is that the effect is not very obvious; The decontamination effect is used to soak pearls, especially the complexation and removal of non-ferrous metal ions in pearls, and also achieve the effect of fading and enhancing luster, but the disadvantage is that the effect is not very obvious, the action time is too long, and due to the strong alkali of ammonia water If the time is too long, the luster and permeability of pearls will be reduced. (3) Contents of the invention [0003] The purpose of the present invention is to provide a pearl wit...
