So, FI got my ring from a very reputable and well known local jeweler. We've been engaged since May of 2010 and in the past few months, my diamonds keep getting loose- especially my center one.
Thanks to my jeweler's lifetime warranty that covers pretty much everything, FI and I haven't had to pay a dime and they've redipped my ring every time. I had to have my ring sent out again since my center diamond was loose, again. They think I might have to have a new setting- and I won't have to pay for it.
That lifetime warranty is saving us right now :-)
