Similar to BlueNile, I used Since1910: http://www.since1910.com/create-your-own-engagement-ring.aspx http://www.since1910.com/create-your-own-engagement-ring.asp... It appealed to me mainly because it was very entertaining to be able to go through pages of raw diamonds and view their exact characteristics (measurements and all) and compare different ones. It's easy to drill down based on certain criteria. I did call them after narrowing down to a few and talked about the different options. I learned that there are non-continuous price steps as you approach certain round carat sizes (0.5, 1.0, 2.0, etc) and so it can save you some money if you go slightly below a round-number size. I got a 0.94 carat diamond with excellent characteristics for significantly cheaper than anything I found at $JEWELRY_STORE. They ship free, and if you're not in NY, no tax, which will save you hundreds right off the top.
