Bracelet with natural stones, stainless steel
Stainless steel is hypoallergenic— it doesn't react with your skin, wet or not. So you don't need to worry about stainless steel jewelry if your skin reacts to metals. And yes, you can shower wearing your stainless steel jewelry and exposing it to water won't cause it to rust.
Hypoallergenic stainless steel: waterproof and does not stain.
