I have enough Qture Ripka jewelry to open an outlet and not has tarnished nor diminished the color of the metal. However, I care for my jewelry too. I make sure that the YGclad isn't constantly being rubbed, for the friction might cause problems. I also store the jewelry either in the original bags, after wiping clear with an anti-tarnish cloth, or a Lori Grenier box. I do not wear my jewelry into the shower or 24/7. I hope this helps you.
