An alcohol-free aqueous pearl treatment composition that includes a water-based emulsion of particle size less than 1.0 microns, wherein, in use, the alcohol-free aqueous pearl treatment composition infuses into pearls to inhibit ageing of the pearls. This disclosure describes a method for the treatment of pearls including the steps of: a) introducing into a bath an alcohol-free aqueous composition, the composition comprising a water-based emulsion of particle size less than 1.0 microns; b) introducing one or more pearls into the bath; and c) operating the bath for a prescribed period to allow the alcohol-free aqueous composition to infuse into the one or more pearls in a first treatment step; wherein, in use, the alcohol-free aqueous composition inhibits ageing of the one or more pearls. |
