We talk about this every couple of weeks. You should search for diamond and/or ring to see what we all said last week.
I have a 10% discount code for Bluenile that expires on the 24th if you're looking to buy. PM me if interested.
Ed - ...and to answer your question; yes, I bought a GIA certified, 1.02 carat, E color, VVS2 clarity diamond from Bluenile a few months ago. I researched this diamond hunt for months and think I got the best deal possible.
