Can Silver give you a "green thumb" ?
Having a green thumb might be great for your vegetable garden, but its not much fun when it was caused by your beloved new Silver thumb ring! So why does Silver sometimes turn some people's skin green?
Well, it's quite rare, but some people are allergic. But not to silver, instead they are allergic to Nickel. So why is there Nickle in your Silver jewelry???
Pure Silver is way too soft and malleable to be used for jewelry. Almost all the jewelry available anywhere is made of Sterling Silver. Sterling Silver is defined, by law, as 92.5% pure silver, and 7.5% other metals. The other metals harden the silver and give it strength. The most commonly used "other metal" is copper. However, nickel and/or other metals are sometimes used, and it's the nickel that can cause one's skin to turn green.
So if you've ever had Sterling Silver jewelry turn your skin green, then you know you are one of 2% to3% of the population that's allergic to nickel.
