I purchased a blue nile wedding band and everything went well until a few weeks in when it got scratched. It's a tungsten band, but I figured I'd live with it. Then after only having the ring for three years it has cracked. There was a lifetime guarantee when I bought the band and free repairs. Blue Nile is unable to honor either of those commitments. I am severely disappointed in their customer service and the quality of the ring. They no longer sell the particular band on the website, so I assume they realized it was a flawed product—which I hate to say because it's my wedding band and has a great deal of sentimental value for me.
