Abstract
Process for the treatment of pearls. Comprises the stages of: a) preparing a solution which comprises the following components: silver nitrate solution having a silver nitrate concentration of between 0.48 M and 0.72 M, water-based wood dye having a yellow colour, and alcohol, the percentage by volume of the solution being between 70% and 90%, and the percentage by volume of the dye and the alcohol being between 5% and 20%, b) heating the solution, c) placing the pearls in the solution when it boils, d) washing the pearls, and, optionally, e) passing the pearls through hot oil. In this way the pearls are given the appearance of a noble metal, the cost of this treatment being substantially less than that of the treatments currently in use.
