re: Engagement ring shopping/valuation

Final update for this thread. Got the ring in the mail about 3 weeks after ordering it (got it from James Allen online). It came in a nice package with its diamond certificate. It's very nice quality, looks just like it did on the website. The .46 carat diamond is perfect. Big enough to grab your attention but not over the top; modest and elegant. Don't let anyone tell you you need a .75 or 1 carat diamond. You can in fact get a very nice engagement ring for under $2k. Thanks to all who provided advice. I proposed and she said yes.
