Description Neck Chain made of Silver 925o A simple and elegant neck chain made of pure silver 925o. You can find it in two sizes, 50 and 60 cm, and in combination with a cross or an amulet, it is an excellent gift for our loved ones. How do we clean the neck chain if it turns black? These neck chains consist of pure silver 925o, which blackens, i.e. oxidizes, but can easily return to its original state. With a damp cloth or toothbrush and a little white toothpaste, rub gently and rinse. Another alternative is to put half a cup of hot vinegar and two teaspoons of baking soda in a bowl. Add the silver object you want and after leaving it for two to three hours then rinse well. Finally, in a container with hot water pour an effervescent Panadol tablet and put the silver jewelry inside.
