Silver jewelry needs care if you want them to last for a long time. Not caring for them would only make them tarnish.
Keep silver jewelry away from direct sunlight. Keep them in a tarnish-proof material lined jewelry box which you can keep where sunlight won’t reach them directly. Make sure you arrange them properly so that they wont clump with each other.
When cleaning silver, use a polishing cloth. Do not use bleach or chlorine when cleaning silver. Even dips should be avoided as much as possible. Use mild dish-washing liquid diluted in water. Dry them well on a soft tarnish-proof cloth before storing them.
