So far so good with the jewelry I’ve been wearing it pretty much since the day I got it now I haven’t took any showers in my jewelry, but I do know that it is waterproof if I happen to get wet or sweat I did wear one necklace while I was sweating doing an activity outside and it did not tarnish or change color or anything so I’m happy about that. Hopefully this jewelry stays the same color for a long while I love how it looks on my body.
