I got this to replace a cheap chain (that broke twice) for my girlfriend's necklace.  First off, this one appears very durable without looking too thick.  I think it will hold up great.  It is also very beautiful.  It is definitely sterling silver, but it almost has a white/pearl tone to it.  The only thing that is a little misleading is that the lengths run small.  I saw a couple of other people say the same thing.  I got the 18" and it is barely 17" including clasp.  This was not a problem for my girlfriend, and she actually liked it better, but I just wanted to warn people to take that into consideration.  Once again, great product, just rethink lengths if need be.
