Review on 925 Sterling Silver Cable Chain Necklace, Italian Solid Nickel-Free Lobster Claw Clasp - 1Mm/1.5Mm Thickness, Available In 14-30 Inches by Zoey Vaughn

Got it as a gift. New one looks beautiful.I see a lot of complains about those chains turning black or green, leaving marks.Guys, you need to know if you buy silver - you agree to that from very beginning.Silver does oxidize! It's NORMAL! (especially when we sweat a lot in the summer) It does turn black, that's why for centuries people were cleaning / shining silver. If you get green marks from silver - then it probably had copper added to that fro sturdiness (100% silver is very soft). Usually silver you buy in the store is 925, means 92.5% of silver, the rest 7.5% is - added metal for sturdiness.If it's pretreated - it might help for a while, but it's a chain, links rub on each other, so eventually this treatment will wear off (my sister actually was allergic to rhodium - commonly used to treat silver - so think about that too).I love silver (untreated), because it also has healing properties - used as my very first ear-rings - freshly pierced ears healed very fast!My way to go with it - when you chain (or any other silver piece of jewelry) lost it's shine - take an old tooth brush, toothpaste (any, doesn't need to be some special one) and rub it for a bit on the palm of your hand (usually minute is more than enough), rinse, wipe dry.You're welcome!
