It is very important to avoid that your jewelry does not get scratched when in contact with other items such as: clothes, desks, screens, couches etc.. they should be protected individually. But also you should always keep it in a safe place once you take it off from your body as it tends to get dusty.
Each piece should be placed in its case or its individually wrapped or in a separate compartment of the jewelry box. Chains and necklaces must be closed, laid flat and wrapped. Never put more jewels all unprotected. When traveling, a simple piece of tissue paper to wrap them enough.
