Putting the pure silver beads that have begun to oxidize and discolor together with the pure silver beads that have not yet oxidized and discolored will accelerate the oxidation and discoloration of those silver beads that have not yet begun to discolor? It is not contagious. If you want the beads to be equally black, buy a piece of sulphur soap and wash it. When silver sulfide forms on the surface, it will be black.

If you want the silver pearl to be bright and white, you should wash it with toothpaste, but toothpaste will form scratches on the silver surface, because the principle of toothpaste washing silver is that particles grind off the oxide on the silver surface.
