Product Care

Product Care

Metallic plating can tarnish depending on the environment it is kept in but tarnish remover can be used to clean and remove tarnish from jewelry. Unfortunately plating will wear off after a while but here are some recommendations you can take to make it last as long as possible!

Tips

Avoid rubbing plating.

Always take off your jewelry when dealing with cosmetics and chemicals, such as soaps, shampoos and perfumes.

Do not expose to high temperatures.

Remove jewelry when swimming in salt water or heavily chlorinated pools as they can damage the plating.
