This is a lovely chain.  It is very bright and shiny. The pendant i bought this for, is a bit heavy, which is why i got the 1.9mm.  It is perfect.  I was concerned it might be too thick, but it is not.  Works beautifully with the pendant.  I have a nickel allergy, and must have 925 sterling silver.  I have been wearing this 24/7 for almost 2 weeks.  No problems.  It is perfect! I got the rounded box chain for sturdiness and comfort.  I could not be happier! I have shoulder length baby fine hair.  I does not get caught in this chain.  In my opinion this chain is perfect!  I will most definitely buy from this seller again. Service is great! Quality is great! Packaging is great! Price is fabulous!  Thank you Bling Factory!
