*Jewelry is not indestructible. Take care to avoid sleeping in your jewelry, and avoid exposing it to harsh chemicals.
*store earrings in a zip top baggie . The baggies will prevent tarnishing.
*Storing jewelry in a humid space will accelerate tarnish, but it is easily to clean them.
*Do not use polishing cloths or any chemicals on the surface of stones. Instead, wipe them with a soft cloth.
