Gold jewellery is generally less prone to tarnishing and discoloration than silver jewellery.Silver may require more frequent cleaning since it does tarnish quickly and will tarnish at different rates. In the past, I've seen some clients with a chemical composition such that it tarnished a piece of silver jewellery within a day! The speed at which the piece tarnishes depends on your body chemistry. Understanding the specific properties of the metals in your jewellery can help you develop the best maintenance routine.
