I wear a lot of necklaces and other jewelry. I've noticed that once I've worn a pair of earrings or a necklace, it develops this really gross smell - kind of like onions, but more unpleasant - that comes off on my fingers when I touch the jewelry. It gets worse over time, especially when the jewelry discolors. I mostly wear costume jewelry made of steel or pewter (I'm allergic to nickel), but I have a high-school ring (I don't know what material it's made of, maybe low-caret gold or a gold blend), and it doesn't smell. I feel like I'm going crazy, since I'm the only one who seems to notice the smell, and when I've asked jewelry vendors for help, they just stare at me and say no one has ever complained about their jewelry having a weird smell. I'm paranoid that somehow my own body chemistry reacts with metal and makes it smell bad and discolor. Is it normal that i think my jewelry smells?
