It is a good idea to use a silver polishing cloth. If the jewelry has a smooth surface and small stones, you can use a cotton cloth or silver polishing cloth and then rub the same gently.
However, it is best to avoid using polishing over the stone surface. Also, your hands may blacken, and you may need to clean these up.
Also, it is important to note that silver, silver-plated or silver-filled earrings, etc. need different types of care and maintenance. It is important to seek professional assistance to ensure that you take appropriate care of these metals.
