There are a number of reasons for silver to suddenly begin to tarnish. Unworn silver will often tarnish much more than worn, so one day you open a drawer or box and BAM! it's black as coal. Also, changes in your diet and/or body chemistry can allow for sudden tarnish. It's the same reason that I can rub a highly tarnished object in my hands and it comes clean and shiny. I have a high acidity level in my skin. lower acidity, more tarnish. Some silver jewelry is given a clear coating or a rhodium plating to prevent tarnish. when these wear off through normal use, tarnish city. Lucky for us, tarnish is more of an annoyance than a real issue. anything from a polishing cloth to vinegar and a rag can be used to remove the unsightly black oxidization we call tarnish. take care and good luck.

Yes! Let me explain: I bought a set of three stack rings at Target in California (not recently...this was awhile back, so I don't want to bag on whoever owns the jewelry counter there now). These rings were on a card that said "Sterling Silver". I was thrilled with them and wore them every day for the next few years. Then I began to notice that they weren't looking shiny and silvery like the rest of my .925 sterling silver and tried to polish them. It didn't help. It became obvious to me that the silver was wearing off and that another metal was underneath. When I tried to return them at the store, they told me too much time had elapsed and additionally, that the jewelry department was leased by a third party, so I'd have to take it up with them. Since then I'm very careful about the "Sterling Silver" I buy! I want to pass my jewelry on to my kids, not some junk someone else passed off as genuine!
I think it was in 1906 Gold and Silver began stamping, as required. Later the law was amended to add Gold and Silver would now have to show its content, i.e.: 10kt, 14kt, 18kt, etc. or .925, .800, etc.

Electroplating was first discovered in 1805 but was not used commercially until 1840. By 1857 a cheaper process was found and it began to be used on inexpensive items like costume jewelry. It was about this same time that EPNS (electro plated nickel silver) was marked on pieces to indicate electroplating.

The notion of silver harming vampires comes from Marvel Comics. From there, it made it's way into popular culture in movies and television. Silver does not affect vampires in the folklore. It doesn't even harm werewolves either for that matter. The use of silver as a weapon against monsters began with the Wolfman film of the early 1940's. Sunlight does not traditionally harm vampires either. That began with Nosferatu (the 1922 silent film).
